In today's environment, the processing, refining and petrochemical business is becoming more and more competitive and every plant manager is looking for the best quality products at minimum operating and investment costs. The traditional PID loop is used frequently for much of the process control requirements of a typical plant. However there are many drawbacks in using these, including excessive dead time which can make the PID loop very difficult (or indeed impossible) to apply.
Advanced Process Control (APC) is thus essential today in the modern plant. Small differences in process parameters can have large effects on profitability; get it right and profits continue to grow; get it wrong and there are major losses. Many applications of APC have pay back times well below one year. APC does require a detailed knowledge of the plant to design a working system and continual follow up along the life of the plant to ensure it is working optimally. Considerable attention also needs to be given to the interface to the operators to ensure that they can apply these new technologies effectively as well.

Distributed Control System (DCS) Applications, Selection & TroubleshootingpetroEDGE
Since the first Distributed Control System was installed in the late 1970’s, the concept of DCS has swept alternative control technologies from the field. The substantial growth, in the construction of plants in the traditional heavy process industries, such as power generation, refining, oil and gas, water and petrochemicals, is driving significant growth in the utilization of DCS. The broad architecture of a solution involves either a direct connection to physical equipment, such as switches, pumps and valves or connection via a fieldbus communication system.

Aplication of on line data analytics to a continuous process polybetene unitEmerson Exchange
This Emerson Exchange, 2013 presentation summarizes the 2013 field trail results achieved by applying on-line continuous data analytics to Lubrizol’s continuous polybutene process. Continuous data analytics may be used to provide an on-line prediction of quality parameters, and enable on-line detection of fault conditions. Information is provided on improvements made in the model used for quality parameter prediction, and how the field trail platform was integrated into the process unit. Presenters Qiwei Li, production engineer, Efren Hernandez and Robert Wojewodka, Lubrizol Corp., and Terry Blevins, principal technologist at Emerson, won best in conference in the process optimization track for this presentation.
The DeltaV PIDPlus is based on a modification of the PID reset and rate calculation to account for non-periodic measurement updates. An alternate approach is to use PID with a modified Kalman filter or modified Smith Predictor. Test results are presented that compare the PIDPlus to these alternate approaches.
In this presentation we address the implementation of a scalar Kalman Filter for use in closed loop control of industrial process that is characterized by one manipulated input and one controlled parameter. A DeltaV linked composite is described that allows Kalman filtering to be used with the PID block in closed loop control. Also, information is provided on a DeltaV module that may be used to get more familiar with the Kalman filter in a test environment. The Kalman Filter composite and test module may be accessed through application exchange at the DeltaV Interactive Portal
Application of online data analytics to a continuous process polybutene unitEmerson Exchange

The author has received the GSK Excellence Recognition Award in acknowledgement of the importance and success of this project.
Presented by Emerson's Michael Pearson and Roy Gueldenzoph at the 2011 Emerson Exchange in Nashville, TN USA.
Abstract: Many measurement challenges exist when monitoring high temperature assets such as Arc Furnaces, including high temperature, moving platforms, and high EMI. Northstar Bluescope Steel had all of these problems and more. They used these points for control, and their only solution was shutting the furnace down and replacing the wires often. By implementing an Emerson Smart Wireless technology, the customer was able to reduce or eliminate all of these measurement challenges, resulting in greatly reduced maintenance costs, and additional throughput.
Maximizing the return on your control investment meet the experts sessions part2Emerson Exchange
The design and commissioning of the controls associated with a continuous or batch process directly impact plant operating efficiency and production quality and throughput. In this session we review techniques that may be used to identify control opportunities to reduce production costs, minimize variations in product quality and to maximize production within the limits set by market demand. Several common application examples from the process industry will be used to illustrate how plant production rate and product quality are directly influenced by process control variation and constraints in plant operation. Starting with an assessment of control loop utilization and automatic control performance, a step by step process is outlined that may be used to identifying and addressing areas where it is possible to justified the time and material costs required to improve control performance. In particular, information will be provided on how to quickly tune single loop control of self-regulating or integrating process and to recognize when variations in control loop performance are not associated with loop tuning. An overview will be provided of tools and techniques that may be used to achieve best control performance over a wide variety of operating conditions. Also, guidance will be provided on when it is possible to justify the cost associated with the installation and commissioning of multi-loop techniques such as feedforward control, ratio and override control. The steps required to commission multi-loop control strategies will be address along with common mistakes to avoid. Also, input will be provided on how to recognize when advanced control techniques such as Fuzzy logic or MPC are needed to achieve the desired control performance. At the end of this session a drawing will be held to give away 10 copies of “Control Loop Foundation – Batch and Continuous Processes”. Many of the ideas discussed in this session are addressed in this book.

5. Introduction Control Loop Foundation address the concepts and terminology that are needed to work in the field of process control. The material is presented in a manner that is independent of the control system manufacturer. Much of the material on the practical aspects of control design and process applications is typically not included in process control classes taught at the university level. The book is written to act as a guide for engineers who are just starting to work in this field. Experienced control engineers will benefit from the application examples on process control design and implementation of multi-loop control strategies.
8. Plant Organization Common terms used to describe plant organization are introduced. Plant Area – classification by name and area number Units within a process Area
20. Measurement Introduction to devices used for basic measurement Magnetic flow meter Vortex flow meter Differential pressure for flow measurement Corilois flow meter Absolute and gauge pressure Temperature – RTD, thermocouple Level based on pressure/differential pressure Level - Radar
21. Device Calibration Concept of devices calibration and configuration is introduce. Role of hand held devices and EDDL is addressed

28. Fieldbus Installation Special requirements for a fieldbus installation are addressed Common terminology is defined: Multi-drop Power conditioner Terminator
29. Control System Documentation Documentation that is typically generated for a control system installation are addressed. The purpose of each document is explained. Reference provided to ISA-5.4 standard for Instrument Loop Diagrams
38. Display Observing Color Usage Operator Graphics and Metrics An operator interface design is addressed by Alarm Standard EEMUA 191 Advocates that alarms should be in alarm color. Pipes, pumps, valves, etc. should not be in alarm colors, or any other bright color.
39. Display Tools Basic tools for construction a display are discussed Dynamos, dynamic elements, faceplates, links for creating a display hierarchy
40. Performance Metrics Example used to illustrate how operation metrics may be added to an operator display Benefits of integrating this type of information into the operator interface
41.
42. A good understanding of these processes is required to design a control system for the plant.Process Characterization
43. Process Definition Process – Specific equipment configuration (in a manufacturing plant) which acts upon inputs to produce outputs.
44. Process Terminology Controlled output (controlled parameter) – Process output that is to be maintained at a desired value by adjustment of process input(s). Setpoint – Value at which the controlled parameter is to be maintained by the control system. Manipulated input (manipulated parameter) – Process input that is adjusted to maintain the controlled parameter at the setpoint. Disturbance input – Process input, other than the manipulated input, which affects the controlled parameter. Constraint output (constraint parameter) – Process output that must be maintained within an operating range. Constraint limit – Value that a constraint parameter must not exceed for proper operation of the process. Other input – Process input that has no impact on controlled or constraint outputs. Other output – Process output other than controlled or constraint outputs.
49. Pure Gain Process When the process output tracks the process input except for a change in signal amplitude, the process is known as a pure gain. The change in signal amplitude is determined by the process gain. For a step change in process input, the process gain is defined as the change in the process output divided by the change in process input
50. Example – Pure Gain Process An example of a pure gain process is the jack shaft used in some boiler combustion control systems. Gain is determine by the length of the lever arms attached to the jack shaft.
51. Pure Delay Process When the process output tracks the process input except for a delay in the output signal, the process is know as a pure delay process. For a step change in the process input, process deadtime is defined as the time from the input changing until the first affect of the change is seen in the process output.
52. Examples – Pure Delay Process Example of pure delay processes are a conveyor belt and a pipeline. Delay is the result of transport time and will vary with the speed of the belt or the flow rate through the pipe.
53.
54.
55. First Order Plus Deadtime Process Most process in industry may be approximated as first order plus deadtime processes. A first order plus deadtime process exhibits the combined characteristics of the lag and delay process.
67. Workshop - Process Characterization Three example processes are include in workshop First order plus deadtime Integrating Inverse response Web site is accessed to perform step test. Only a web browser is needed – no software to install.
68. Control Objective For the case, production is greatest when the band of variation is reduced to zero and the process parameter is maintained at the value corresponding to maximum production
69. Impact of Operating Target To benefit from improvement in control, the loop must operate at the target that provides maximum production. The plant design conditions may be used as a guide in establishing setpoints for best operation
70. Operating at a Limit For this case, maximum production is obtained by maintaining the process parameter at a limit determined by some plant limitation. How close to the limit you can operate is determined by the quality of the control
71. Impact of Reduced Variability Production improvement is obtained by operating closer to product specification or operating limit.
76. Balancing Control Complexity and Benefits Various techniques may be used to improve the control of a process As the complexity of the control system increases, so does cost for operator training and maintenance The complexity (cost) of the control system should be balanced with the benefits provided The benefits of control improvement may be influenced by market conditions i.e. value of product, cost of feedstock, energy cost
77. Single Loop Control In some cases manual control may be appropriate Manual Loader Block may be used to implement manual control
116. Cascade Control Implementation Selecting FRSI_OPT for dynamic reset in primary loop and CONTROL_OPTS for Use PV for BKCAL_OUT in secondary loop can often improve dynamic response.
133. Example – Ratio Control In this example the ratio setpoint is adjusted using feedback control based on a downstream analysis of the blended material
