proactive and quick maintenance activities." "From these - - - - Plant Operations Management - - 3. Operate & Manage Approved Solve Level Control Loop Problems To Smooth Your Plant Operation Liquid level controls may appear to be “just tank controls” but actually function in key areas such as column feed, column bottoms, inlet separators, reactor volume, or boiler drums.? Level loops often have a surprising impact on plant stability and operator effectiveness.? Properly designed and maintained level loops can absorb variability.? However, many plants encounter level loops that generate variability (by self-cycling), propagate the variability to other vessels, or regularly cause alarms.? We present 10 never-published examples from the oil & gas, LNG, refining, agrichem, and power industries in context of the plant operations.? This presentation will show instrument engineers, process control engineers, and commissioning teams how to rapidly isolate, diagnose, and fix problems. First we need to isolate the problem to a component of the loop, preferably without going to the field for time-consuming (and possibly hazardous) inspection.? Root cause could be in the final control element, control logic, filtering, controller tuning, control strategy, or interactions with other loops.? Level processes have integrating dynamics, so controller tuning may be counter-intuitive. The level loops now perform much better, with less oscillation, reduced disturbance to key flow rates, and greatly diminished alarms.? Benefits include tighter control of product quality, faster startup of units, reduced operator distraction with loops staying in AUTO/CAS, enabling of APC projects, reduced wear on control valves.? The results shown here are typical of all process industries. Measuring the process dynamics with DeltaV Insight, EnTech Toolkit or other method helps to isolate the problem. For problems in the controller, Lambda Tuning gives non-oscillatory response; details of that are in the Short Course. For surge vessels, the tuning philosophy is “How slow can we go?”.? Problems in other loop components can be recognized from our symptom-to-diagnosis-to-cure examples.

Operate & Manage Approved Automating Fertilizer Crystallization Process using Remote I/O, Delta V batch-like? Logic AZOMURES fertilizers factory, an Ameropa company, in order to improve reliability and product variance, it revamped NPK crystallizing plant composed of 20 units - 102 remote operated valves in a cycle of seven hours. Low reliable, old automation based on hundreds electromagnetic relays, operated for years only in remote manual mode, it has been replaced by a new one integrated in Delta V DCS. Field interface is made by Profibus DP network of SIEMENS remote I/O modules: ET200X. Logic has been created in Delta V to solve the interlocks and the operation of units in automatic mode, manual mode and out of service/ test mode. Units work synchronized between them during crystallizing phase and synchronized with filling/collecting units after attaching them during filling/dumping phases. Including all process phases: filling, crystallizing, dumping, operation is now full automatic, crystallization units are synchronized in ring even some of them are out of service or in manual mode. Start-up of crystallization plant has been performed without to stop the fertilizer production during site works: the revamped units has been operated in ring together with not revamped ones. Now, the NPK crystallization plant is operating almost 99% in full automatic mode. Manual mode is used only for equipment failure situation. Operational costs have decreased: 10% for pumps mechanical maintenance and 30% for instrumentation maintenance. Plant throughput in crystallization phase has increased with 3-5 %. Product quality has increased due to strictly temperature operation As the crystallization process involves only one recipe, Delta V Batch executive and advanced unit modules have not been used; these has been replaced in Control Studio strategies by independent working equipment modules based on advanced classes and synchronized between them by messages, with dynamic references and using limiting allocation parameters for common units like in Delta V Batch logic.

Operate & Manage Approved Do you know if your system is healthy? System Health Monitoring dashboard has the answer! Even a small DeltaV System has hundreds of diagnostic parameters relating to individual components, software and hardware. Additionally, these diagnostics come from disparate sources and require various applications and interfaces. Imagine driving a car with hundreds of speedometers! Consolidating these diagnostics into a single dashboard allows the DeltaV System administrator to "keep his eyes on the road." This session details how Pfizer's batch manufacturing facility in Sanford, NC, utilizes IIoT technology to centralize system diagnostics and enable Connected Services to drive proactive system maintenance. A novel approach was implemented, leveraging virtualization and blending Emerson solutions and custom tools to proactively monitor, trend and stay alert in real-time. Historically, monitoring DeltaV components has been resource intensive, requiring detailed system knowledge. Additionally, there has been no centralized dashboard for monitoring system components and security functions. By deploying virtual SHM, the Sanford site consolidated monitoring into one dashboard that automatically analyzes system health, eliminating the manual monitoring process. System components are continuously monitored using virtualized servers, gaining the productivity of a full-time resource. Diagnostics are locally presented in a centralized dashboard. Data is trended and can be exported into custom graphs for tracking and reporting. Emerson’s Connected Services has provided several proactive alerts, enabling local response to prevent a system disruption. To reduce resources needed for manual system monitoring, the Sanford site implemented virtual SHM. The service was installed on all four production systems and configured to automatically notify the system administrator and Emerson when system parameters reached a defined alert limit. A centralized dashboard was implemented to consolidate all system data into one location.

Operate & Manage Approved Implementing ValveLink and Asset Management Solutions on a non-AMS Platform "Instrumentation asset management is continuing to gain momentum in many industries.? A major challenge is to integrate the device information via the control system into an asset management platform.? This is especially challenging when HART has not always been embraced as the control systems main communication protocol. This workshop will detail steps taken to launch device monitoring/asset management on a non-AMS platform at the CHS Refinery at McPherson.? The primary focus will be monitoring the Fisher control valve asset via ValveLink but also other Emerson/Non-Emerson devices via DD’s and DTM’s." Previous to ValveLink no predictive maintenance activities were in place for Fisher control valves at the refinery.? Through the use of ValveLink a window into the process and the health of field devices has been accessed. Early results are good.? Work orders have been generated against problem devices.? It is difficult at this point to put a monetary value on the success but this will be evaluated. Staring up a non-AMS asset management platform and implementing ValveLink.

Operate & Manage Approved Gas Lift Optimization Application Increases Crude Oil Production Gas lift is a common method of artificial lift for crude production and deliquification of gas wells. The optimization of the process in order to minimize lift costs versus production gains is an ever present concern to all operators. Automated applications can achieve significant improvements? by offering injection alternatives, and by placing the equivalent of a seasoned lease operator, at every wellhead, 24/7 in order to make lift gas adjustments. Due to the relatively low price received for produced natural gas relative to a much greater return for crude oil, there is a tendency for an operator to inject as much gas as possible with the idea to obtain the most oil possible. This is not always the most optimal approach. In addition, manual operations are inherently? slow to react to production changes. One producer? performed a 22 well pilot. The total investment was approximately $45,000.00 per site to add additional equipment. The resulting crude production increased by 40% with a 50% reduction of injection gas required. Economic analysis indicated an average three day payback period, and an overall project ROI greater than 300%. A flow computer/controller installed at the wellhead running a SmartProcess application continually adjusts PID loop parameters in order to optimize the amount gas injection versus liquid production.
