Development and application of advanced process control system for ethylene cracking heaters
摘要
Abstract
The advanced process control systems for the SC-1 type ethylene cracking heaters at Lanzhou Petrochemical Company 460KTA Ethylene Plant were designed, including the average coil outlet temperature controllers, the pass outlet temperature balance controllers, the total throughout controllers. The software and hardware structure of the control systems, the switching logic between advanced control and DCS regular control, the DCS operation interface for advanced control were introduced. The control steadiness and control accuracy for cracking heaters are greatly improved by using the advanced process control systems, and remarkable economic benefit is obtained.关键词
