仪表专业对于切换工艺的设计方案分析

The Instrumentation Design for Swing Process

切换工艺一般是年生产不同化工产品 ,这些产品的生产周期基本是相同的 ,化学特性存在一定的差异。正是这种工艺的特殊性 ,在仪表选型和系统组态方面必须进行综合考虑 :仪表要满足各种工况的要求 ,保证系统运行的连续性和操作的可行性 ,控制费用在合理范围之内。针对这种特殊工艺 ,详细介绍了仪表工程设计中的主要思路。

Within one year a swing process normally produces different kind of products,which have same production circle and not the same chemical characteristic.Therefore it should be taken into account in selection of instrumentation and configuration of control system.The requirements of both of the processes,the continuity of system running,the accessibility of operation,and the cost,especially the special work should be considered thoroughly.The detailed description of the main steps of instrumentation design is presented.
