摘要
本文简单介绍了DCS顺控程序特点和聚乙烯装置生产双峰产品时的催化剂工艺流程、催化剂进料的顺控程序;重点阐述生产双峰产品时使用国产催化剂在工艺生产过程中遇到的问题,通过对这些问题分析和对比原催化剂进料程序、工艺流程,做出对现有顺控程序的修改,满足了国产化催化剂进料工艺要求,保证了国产化催化剂的量产应用。
Abstract
This article briefly introduces the characteristics of DCS sequential control programs and the catalyst process flow, as well as the sequential control program for catalyst feeding in polyethylene units producing bimodal products. It focuses on the issues encountered when using domestic catalysts in the production of bimodal products. Through analysis of these problems and comparison with the original catalyst feeding program and process flow, modifications were made to the existing sequential control program. These changes meet the process requirements for domestic catalyst feeding and ensure the successful mass production application of domestic catalysts.
