Implementation of Zone Transition Control ( ZTC) algorithms for Pumparound, Pusharound, and Raffinate control loops. 对循环回流量、排出量、残液量控制回路ZTC运算法的执行。
Packed tower was suitable for the distillation, horizontal partial condenser was used as top condenser, and pumparound may also be used for triethanolamine tower, which helps to reduce the pressure drop; 精馏塔适合采用填料塔,塔顶冷凝器宜采用卧置部分冷凝器,TEA塔也可采用塔顶泵循方式取热,这些措施利于减小压降;
