摘要
采用原油处理站现有锅炉提供的蒸汽,进行掺蒸汽直接加热稠油处理的新工艺,整个流程掺蒸汽量的大小采用可编程控制器(PLC)控制系统发出指令自动控制,可使蒸汽与原油达到最佳混合,同时降低成本,提高可靠性和安全性。本文介绍该装置的可编程控制器(PLC)控制系统I/O接线图、梯形图。
This article introduces a scheme that includes the stream Injecting heating Device and the device of auto control system,and application of PLC in the system,and gives I/O distribution,ladder programming according to technology procedure.there will be a cut on the cost of the producion so as to improve the safety and make the heavy oil and stream mix most completely.
