Planning and Justifying Control System Modernization Projects
Author: John Dolenc It is nice to hear from our customers and read in the literature that it has become important to not just replace obsolete control system equipment, but to also provide operational improvement. For the longest time I have been puzzled by the idea...
State-Based Alarm Management
The ISA106 committee on Procedure Automation for Continuous Process Operations is chartered with: …developing standards, recommended practices, and technical reports on the design and implementation of procedures for automating continuous process operations. The...
Natural Gas Liquids Fractionation Optimization
Maximizing the recovery of natural gas liquids from natural gas improves margins for midstream oil & gas producers. In an earlier post, Optimizing the Process of Purifying Natural Gas Liquids we highlighted the role of advanced process controls and expertise in...
Applying Technology to Modernize Control Systems
Those of us in the "baby boomer" generation know how fast time goes by. Children grow up quickly and the control systems running our process manufacturing and production facilities age. There's not much we can do about kids growing up quickly, but we do have ways to...
Optimizing Sugar Mill Boiler Performance
Steam boilers are used in sugar mills to generate electricity and for heat in various stages of production, such as crystallization process. This process converts the sugar syrup into sugar crystals. Optimizing the performance of the boilers improves energy efficiency...
Optimizing the Ammonia Production Process
Author: James Gremillion One of the earliest applications of "computer control", a now archaic term, on an ammonia plant was done in 1969 by Weissenfelder and Shah of Borden Chemical and IBM respectively. They were able to implement advanced control schemes in a...
Learn How Guardian Support Will Improve Decision-Making and Optimize Performance
Author: Bob Cruz Guardian Support has long been known as the core element for Emerson's Lifecycle Services for operations management, control and asset management systems. It is a subscription service designed to help improve process manufacturers and producers'...
Optimizing the Process of Purifying Natural Gas Liquids
Author: Chuck Miller It is no secret that the oil and gas producers attraction to the shale fields has been the high BTU wet gas that contains a significant volume of heavier hydrocarbons known as Natural Gas Liquids or NGLs. The purpose of the Natural Gas / NGL...
Inputs for Developing Control System Migration Strategies
Author: Scott Turner When considering replacing your existing control system with a new control system it is important to plan the project up front. At Emerson on a typical Greenfield project, we would write a Project Execution Strategy. This is pretty standard...
Reducing Risks in Scheduled Shutdowns, Turnarounds and Outages
It would be great if plants could run forever after starting them up, but unfortunately, they slowly degrade as they operate. Equipment and assets foul, corrode, erode, rattles and more. Some can be maintained while the process continues to run, but many require the...
How Does Your Control System Measure Up Against Best Practices?
Author: Jocelyn Sexton When analyzing Best Practices, you want to know if your control system is up to par. Not only do you want to know if you're meeting or exceeding industry standards and benchmarks, but you want to ensure your system is reliable and performing...
