原油蒸馏塔汽液负荷软仪表的开发及应用

Development and Applications of Soft-Instruments for Vapor-Liqid Load in Crude Oil Distillation Tower

开发了原油蒸馏塔内部汽液负荷软测量的通用软件。在软件的开发过程中，重点考虑了原油蒸馏塔的一般性特点和工程实用性，并采用了模块化结构，因而所开发的软仪表对这一类塔的计算具有很大的通用性和可移植性。该软件已在一个复杂的常压塔上进行了实施，在线结果满足工业控制的要求。

The universal software for vapor-liquid load softmeasuring in crude oil distillation tower is developed.In the process,the general features and practicalities of crude oil disillation tower are focused discussion.Because of using modular structure,the soft-instrument has large universality and transportability.The software has been put into effect normal pressure tower and be satisfied for the requirment of industry control.
