基于DCS的汽油在线调合系统的设计与实现

Design and realization of on-line gasoline blending system based on DCS

针对罐区无控制系统,所有工作手动完成,基础条件较差以及原始调和方式存在诸多问题,提出了一种基于DCS的汽油在线调合系统的设计方法,详细介绍了系统的选型方案、调和技术方案以及软件设计,阐述了汽油在线调合控制系统的原理特点和实现过程,系统经投用后,极大地提高了油品调合的自动化程度,取得了很好的经济效益。

Aiming at the problems that there is no control system in tank field,all the works need manual operation,the basic condition is poor,and conventional blending method is not good,a design method of on-line gasoline blending system based on DCS is proposed,the scheme of model selection,blending technology and software design are expounded in detail.After the system puts into practice,it improves the degree of automation greatly,and gains the good economic benefits.
