Research and Development of Liquid Level Identification Device and Algorithm of Condenser in Distillation Column Based on Infrared
摘要
Abstract
In the process of tower pressure control by thermal bypass method in the traditional crude oil rectification process,when the content of non-con-densed gas at the top of the tower is high,there is a certain lag in the control of tower pressure,and in extreme cases,there are risks such as evacuation damage of reflux pump and pressure loss,which seri-ously affect the safe production of the unit.In order to solve the above problems,a design scheme of ther-mal bypass infrared level identification device was proposed.The infrared level identification control process was added to the tower pressure regulation process of thermal bypass method.When a large a-mount of non-condensable gas accumulated and caused large fluctuations in operation,the condensate level identification control loop was automatically trig-gered to accurately adjust the liquid level,thereby reducing the risk of thermal bypass tower pressure control and improving the safety level of the device.The accuracy of the liquid level identification model based on digital image processing algorithm was 97.63%,which can meet the needs of industry.关键词
