The constant evolution of the energy industry requires frequent innovation and quick responses to meet the inherent challenges and changes. In the coming months and years, certain trends stand out as significant threats to the power grid. Only by anticipating and preparing for each of these can we help you to ensure stability and continue to thrive. Here are some imminent risks that companies in the energy industry will face and how to begin solving for them: 1. Threat: The necessity of increased cycling will also, unfortunately, put added strain on your operations and can result in stressed equipment, even to the point of complete breakdown. Solution: Implement diagnostic solutions that can predict danger zones before they worsen by carefully monitoring system performances. Ensure sufficient equipment maintenance and give your teams ample time to react, rather than waiting for dangerous situations and forcing them into panic mode. Not only can you manage cycling through these adjustments to your power plant, you will see clear boosts in operational agility, without losing productivity or putting excessive wear on machinery. 2. Threat: Increased use of renewable energy sources coupled with their unpredictable nature causes spikes in demand that are difficult to anticipate and compensate for during production. Solution: Certain technologies can optimize flow and performance to respond to whatever the current demand requires, even as it fluctuates. To circumvent surprise, carefully schedule downtime and establish maintenance routines that assure you your products are performing optimally. This will build on your own sureties, regardless of the rise and fall of energy needs. 3. Threat: Half of the electric utility workforce will retire within the next ten years, as predicted by the U.S. Bureau of Labor and Statistics, and this disappearing workforce means fewer resources and added stress on remaining staff. Solution: People are now an invaluable resource—and in order to compensate for the decrease in numbers, it’s important to enhance current staff effectiveness and offset for the coming losses. Through extensive training and implementation of new systems, you can maximize the talent that remains while utilizing the full capabilities of machinery automation. 4. Threat: Shifting EPA regulations will continue to complicate the way you determine costs and hiring needs. Solution: As research continues to shed light on energy questions, your challenge will be to meet this new information and rise to each occasion. Just visible on the horizon is an inevitable transition to natural gas. And with that must come an adjustment to your operations. Partner with experts who can navigate the logistics of the change while advising and guiding in the implementation of each new reality. Your business is too important to leave it vulnerable to changing threats and constantly emerging challenges. Prepare to meet every energy-related difficulty by partnering with Micro Motion and taking advantage of all of the experience we have to offer.

Forum Post: A Solution for High Turndown Applications
Process control applications with high turndown requirements can be difficult when using a pressure regulator or a control valve. For those of you who are not familiar the concept of turndown ratio it is simply the ratio between the maximum flow requirements and the minimum flow requirements for an application. Pressure regulators tend to have very large turndown capabilities and depending on the type of regulator and the application the turndown can be appear almost infinite. However, there are applications where a single control device cannot meet the turndown requirements. When a pressure regulator or control valve reaches its turndown limit, the result can be instability or even excessive wear on internal components leading to a lower mean time between repair (MTBR). A common solution for applications with high turndown ratios is the installation of a minimum flow regulator. The minimum flow regulator is installed in parallel with a larger pressure regulator or control valve and sized to handle the low flow process conditions. When using two regulators in parallel, the minimum flow regulator will have a higher setpoint than the larger regulator and as demand increases, the downstream pressure will droop allowing the larger regulator to open. When in parallel with a control valve, the minimum flow regulator is typically set to achieve a minimum flow rate at the required pressure setpoint. Minimum flow regulators can be found in a variety of applications including steam systems with winter and summer loading requirements, fired heater fuel gas systems that require a small amount of start-up fuel gas, or even tank blanketing applications where pump-in and pump-out rates are dramatically different. If you have other applications where you use minimum flow regulators, please share below.

Blog Post: How to Optimize Cascade Control Systems in Vessel Heating and Cooling
The post How to Optimize Cascade Control Systems in Vessel Heating and Cooling first appeared on the ISA Interchange blog site. The following insights are part of an occasional series authored by Greg McMillan , industry consultant, author of numerous process control books and a retired Senior Fellow from Monsanto. Editor’s Note : This is Part 2 of a four-part blog series on smart automation of vessel heating and cooling. Click here to read Part 1 , on critical aspects of jacket and coil design in vessel heating and cooling. In this post, I look at how to make sure the cascade control system is intelligently designed to meet process requirements in terms of vessel and heat transfer surface temperatures. Whether inlet temperature or outlet temperature is used depends upon the source of upsets and constraints on heat transfer surface temperature. In either case the jacket or coil temperature control loop must be fast. Cascade temperature control is the most prevalent strategy applied where the primary vessel temperature PID provides a setpoint to a secondary jacket temperature PID for the throttling of hot and cold fluids (Figures 1 and 2). The use of cascade control offers considerable performance improvements in terms of reducing the peak and integrated absolute error (IAE) from disturbances. The jacket or coil temperature controller can correct for disturbances to the jacket before they affect the vessel temperature. The jacket or coil temperature loop also isolates process and valve gain nonlinearity from the vessel loop. For a negligible increase in the heat of reaction compared to the heat transfer capability, the process gain for the vessel temperature loop approaches unity. Insight: Jacket or coil temperature loops prevent the vessel temperature loop from seeing utility system and valve nonlinearities and disturbances. Figure 1: Control of Jacket Inlet Temperature Figure 2: Control of Jacket Outlet Temperature A jacket or coil temperature loop can isolate the effects of process and valve gain nonlinearity from the vessel temperature loop. Jacket or coil inlet temperature control provides quicker correction of utility disturbances and better prevention of cold and hot spots. Outlet temperature control offers a smoother response by attenuation of mixing disturbances and phase discontinuities. A change in outlet jacket or coil temperature for the same production rate or batch cycle time and same vessel temperature can provide a warning of an increase in heat transfer surface coating or fouling. The jacket or coil temperature control must be fast and responsive to the demands of the vessel temperature controller. See Greg McMillan’s new ISA book Advances in Reactor Measurement and Control for an extensive view of practical opportunities for designing control strategies to achieve product quality and maximize yield and capacity in different types of fermenters, bioreactors, and chemical reactors. For a faster and more uniform measurement the temperature sensor should be in the pipeline about 20 pipe diameters downstream of the outlet of an exchanger or jacket rather than in the equipment for a faster and more uniform measurement of the heat transfer fluid. Pipeline velocity and turbulence reduce the sensor time constant and process noise from the splashing of level, hot and cold spots, and mixed phases. The sensor tip should be near the centerline of the pipe with a sufficient immersion length to make conductive heat loss negligible. For highly exothermic fluidized reactors boiler feed water (BFW) is added under level control and the reactor temperature PID output is the jacket outlet steam pressure PID setpoint or coils are switched in and out of service. The jacket temperature control schemes are suitable for batch as well as continuous operation. Coils generally offer a faster temperature response than a jacket by a decrease in the volume of the heat transfer fluid and an increase in the velocity. Both of these work to decrease the process dead time, which is the coil volume divided by the utility flow rate. The increase in velocity increases the heat transfer coefficient but this is partially offset by the decrease in surface area. An increase in the product (UA) of the overall heat transfer coefficient (U) and surface area (A) will decrease secondary process lag in the thermal response. The transition in split range operation is faster with a coil than a jacket which is useful for a valid transition between hot and cold utility streams but can be problematic for unintended transitions from valve stick-slip and an integrating response in the process or controller. Insight: The more aggressive temperature effect and faster transition between heating and cooling by coils help deal with the highly exothermic and fast gas reactions but the switching of coils and split range transitions are more disruptive to vessel temperatures. Whether the secondary loop uses coil or jacket inlet or outlet temperature is often a matter of tradition for a particular company or process industry. The dynamic response of the cascade control system to vessel disturbances such as feed and reaction rate are the same for coil or jacket inlet and outlet temperature control. Coil or jacket inlet temperature control will correct for changes in cooling or heating utility supply temperature and pressure sooner than the transportation delay through the coil or jacket. The coil or jacket loop process dead time is also less by the amount of this delay, allowing a faster reset time setting and faster correction of valve nonlinearities. For crystallizers, cold spots can cause the formation of fine crystals that coat the coiling surface causing an excessive heat transfer lag and an upset to the population balance of desired crystals by not growing into the proper crystal size. For biological operations and sensitive products local hot spots can decrease capacity and quality. At the coil or jacket inlet the mixing of the recirculation with the hot or cold makeup flow may be incomplete and the discontinuity in the transition from hot to cold may be more abrupt. The location of the temperature sensor on the jacket outlet offers time for mixing and volume for smoothing transitions. Less measurement temperature noise can translate to a higher controller gain and less overreaction to the discontinuity at the split range transition. Insight: The use of the jacket inlet for the secondary control loop can correct for utility disturbances more quickly but is more susceptible to noise from mixing and phase changes. The difference between the vessel and the jacket outlet temperature (approach temperature) can provide an inferential measurement of the heat transfer coefficient (U) for a constant jacket circulation flow, a given production rate, and the heat transfer area (A). The approach temperature increases as UA decreases. For residence time control in liquid vessels the increase in level will increase the heat transfer area covered by reactants and product offsetting the increase in heat release with production rate and eliminating the need for production rate and level correction. For fed-batch vessels and continuous vessels without residence time control, a correction for level is needed to compute U from UA. Insight: The difference between vessel temperature and jacket outlet temperature (approach temperature) can be used to compute the heat transfer coefficient for a constant jacket flow. For the coil or jacket temperature control to provide rapid adjustments of cooling and heating for disturbances to the coil or jacket and setpoint changes from the vessel temperature control, the coil or jacket PID response needs to be fast, which may be achieved by a fast sensor and fast tuning. A tight fitting sensor bottomed in a thermowell made from a high thermal conductivity metal with a tapered tip near the pipe center line provides a fast measurement. Spring loading can ensure that the sensor sheath is bottomed. The clearance between the sheath outside diameter and the thermowell inside diameter must be minimized and the fluid velocity must be maximized. While grounded thermocouple sensors are a few seconds faster in responding than resistance temperature detector (RTD) sensors, the difference is insignificant compared to the effects of thermowell design and fluid velocity. The greater sensitivity and lower drift of an RTD is important for jacket as well as vessel temperature measurements. The lower drift reduces maintenance and the higher sensitivity provides faster recognition. The use of RTDs also facilitates more accurate online heat transfer computation for process diagnostics and inferential measurements of reaction rate. Thermocouples are preferred for temperatures above 400 o C where RTD insulation resistance and sensor integrity become problematic. A high PID gain provides a faster setpoint response. The jacket temperature controller has a self-regulating process response with a maximum PID gain that is about half of the open loop time constant divided by the product of the open loop steady state gain and dead time. The minimum reset setting is about 4 times the loop dead time for the jacket temperature PID. The elimination of offset from setpoint in the secondary jacket temperature PID is not as important as an immediate response to setpoint changes from the vessel temperature PID. Consequently, proportional action is more important than integral action and robustness to changes in dynamics is better achieved by increasing the reset time. External reset feedback in the primary vessel temperature PID prevents the manipulated jacket or coil secondary PID setpoint from changing faster than the jacket or coil temperature can respond but a faster secondary PID response dramatically improves the tightness of vessel temperature control. Insight: RTDs with a tight fit in a tapered thermowell at the pipeline centerline and a PID tuned with more proportional action than integral action provide the fastest secondary loop response. Determine whether the major source of jacket or coil temperature disturbances originates from changes in the utility temperature or pressure or from mixing and discontinuities and accordingly choose whether the jacket or coil temperature should be controlled. Make sure the temperature measurement is fast and representative of the true jacket or coil temperature. Tune the jacket or coil temperature controller for a fast setpoint response to immediately start to meet the demands of the vessel temperature controller.

Forum Post: Reverse Generics Wave
Within North America, we are seeing what we at Emerson lightly refer to as a ‘Reverse Generic Wave’ of overseas generics manufacturers building secondary and finishing facilities to sell products in the local market to meet local regulations. This market shift might be accelerated further by a new bipartisan bill introduced late last week in the U.S. The Fair Access for Safe and Timely (FAST) Generics Act aims to close loopholes that allow brand name drug companies to deny their generic rivals access to their formulas for necessary testing and, ultimately, FDA approval. Good news for consumers – More access to affordable, life-saving medications. I’m curious how you think closing the loopholes will affect brand name and generics manufacturers?

Blog Post: Data Integrity for Compliance, Audit Readiness and Performance
Pharmaceutical and biotech manufacturers have stringent regulatory compliance requirements. These requirements must balance with the need for improvement and optimization to run safely, efficiently, profitably and in line with the business and quality objectives. In a Pharma Bio World article, The Crossroads of Compliance, Audit Readiness, Profitability, and Data Integrity , Emerson’s Michalle Adkins opens: True compliance and audit readiness starts with a well thought out, holistic, structured approach that aligns with an organization’s business and quality objectives. Profitably and safely managing a batch production facility while maintaining the compliance and quality of the product and production facility is a challenge that every pharmaceutical and biotech company faces. Michalle notes that the integrity of the data from the manufacturing process and associated business processes are key to understanding and detecting sources of variability to: …prevent deviations…essential to running an operationally excellent facility. There are several ways to reduce variability. Mistakeproofing processes, eliminating sources of controllable variability, and knowing how to respond to the remaining sources of variability are all important methods to consider. Michalle describes several ways to attack variability. Near the top: …is automating production and business processes. Automation is a solution that enables predictability, detection of variability, and the ability to appropriately respond to remaining variability. Compliance ready systems along with a structured project approach are keys to ensuring the data integrity of these types of solutions. Involving experienced people is also important, whether an: …internal resource or an external consultant have a breadth of experience working with many companies in the industry to take advantage of best practices, incorporate a view of where the industry as a whole is heading, and know what automation solutions are available. From a technology perspective, Michalle highlights the importance of the ISA-95 model as guidelines for addressing business and manufacturing needs and integrating automation at all levels. ISA-95 Enterprise/Control System Integration For Layer 1: …the focus is on properly sensing and manipulating the production process. The primary concern for level 1 is standards adherence: equipment must comply with and enforce quality regulations. … It is important to select intelligent sensors that enable prediction of downtime and reduce process variability by keeping devices and instruments performing at their best. Improving data integrity includes smart instrumentation that is: …delivered pre-calibrated with documentation and certification to ensure that regulatory standards are met, building compliance into the architecture. At Layer 2: …the focus shifts to monitoring processes, providing supervisory and automated control of the production process. With proper automation, organizations can limit variability, which means simplifying compliance. Batch manufacturing requires sophisticated sequencing across a plant, while at the same time ensuring that only the correct equipment is used, while in the correct state. Defining the process specific requirements and using best in class process control systems (PCS) are keys to success at this layer. Layer 3: …connects the concepts of the organizational management system (ERP) to the activity taking place on the production floor. Michalle cautions: …operating without a data integrity plan often results in production managers trying to connect isolated islands of process, quality, operations and logistics data by paper, databases, and other mechanisms which may incidentally cause a data integrity issue. … An MES [ manufacturing execution system ] solution can be used to help minimize paper-based traps with electronic verifications of equipment and recipes to reduce variability and deviations, reducing errors associated with these activities. When properly integrated with the PCS and asset and machinery management, the MES provides access at time of use, ensuring all production records can be easily produced, stored, and approved with electronic signatures. Layer 4: …is the layer at which business planning and logistics happen. At this level, planners develop the basic plant schedule, monitor material use, track ordering/delivery, and schedule shipping of product. Business performance is impacted by inventory control and shipping schedules. If production and materials use records don’t correlate with inventory and delivery records, and organization can find itself producing too little product, or having to store excess inventory that simply sits around. Read the article to see specific ways that technologies can address the data integrity and work processes at each layer to improve compliance, audit readiness and overall business performance.

Forum Post: What to do with Controller Peer to Peer Connections?
A logical approach to modernizing a legacy distributed control system is to do it in a phased manner, migrating a controller at a time. However, this creates a situation which must be addressed and planned for in any engineering and cutover strategy. In a recent analysis I performed on a Foxboro I/A system running a power plant, I discovered that 8% of the 11,000 connections in the logic configuration are controller Peer to Peer. How do you deal with these interactions between controllers? Are high level Unit statuses being communicated? Is control being performed peer to peer? Will a phased cutover plan require physical hardwiring between the old and new system to accommodate the peer to peer traffic? Consolidating controls into fewer controllers can help minimize the number of peer to peer connections that must be dealt with. It could be that a phased controller migration may not be possible because the controls are so highly distributed. These are just some of the things to consider when engineering and devising a cutover strategy for the modernization project. Running an analysis and knowing what the peer to peer connections are and planning for them will make for a more successful modernization project.

Blog Post: Optimizing Oil and Gas Well Chemical Injection Processes
Given the presence of water in oil and gas producing wells, corrosion in the piping is a problem that must be mitigated. Producers inject chemicals into the production stream to minimize the oxidation process. The cost of these chemicals can have an impact on the overall performance of the offshore platform or onshore production field, especially in this era of lower oil prices. In this quick 2:18 video, Optimizing Well Chemical Injection through Flow Assurance , Emerson’s Laura Schafer describes how to reduce the cost of the chemicals and overall operating expenses by not injecting more than is required to prevent corrosion. Laura notes that when oil prices were higher, it was not as much of an issue if producers were over-injecting chemicals. Producers over-injected because the cost of under-injecting could be catastrophic in terms of safety, environmental incidents and downtime. This over-injection could be by up to 20% more than is required. One oil and gas producer shared that this over-injection cost them up to $2 million USD per year—for a single well. In this instance, they did not have confidence in the reliability of their measurement and control system. (Please visit the site to view this video) An effective flow control solution relies on three things—monitoring, control and management. To know how much chemical to inject, producers need continuous visibility to changes in the flow production. Laura shares ways to improve monitoring including continuous corrosion monitoring , continuous downhole pressure and temperature measurement , and continuous multiphase measurement of production flow rates and compositions . These continuous measurements provide confidence for how much chemical to inject. Combined with distributed control systems or SCADA systems , the chemical injection process can operate under closed loop control. These systems also provide remote access to effective manage chemical injection across many production areas and geographies.
