Improving Polymer Reactor Control Performance
Emerson’s James Beall presented Novel Techniques to Improve Polymer Reactor Tuning at AIChE virtual conference based on a project he worked on. Reactor control is complex with many interactions between control loops. The way to tackle this challenge is to start by identifying the process dynamics and create a realistic process simulation to identify improvements in the control strategy to address the complexities.
Distillation Column Automation Control and Optimization
The cold section of an ethylene plant is responsible for cooling and purifying the product-grade ethylene, propylene and other bi-products from the cracking furnaces. Cracked gas is cooled in transfer-line exchangers which produce steam from the effluent gas energy. Gas is further cooled with water in the quench column, scrubbed and dried before being compressed in the cracked gas compressor and fed to the cold box.
