One company has built a 500 kt·a-1 light hydrocarbon aromatization unit,which has been affected by low self-control rate and unstable product income since its commencement.The automatic control rate of instruments is an important production indicator for refining and chemical equipments,which has an impact on energy consumption and product quality.The correct setting of PID parameters in the control circuit determines whether the control circuit can be put into use normally.In order to improve the automatic control level,a company carried out DCS automatic control system optimization and PID parameter tuning of light hydrocarbon aromatization plant to improve the automatic control rate and stability rate of the plant,so as to achieve the automation of the whole process,reduce the operating intensity of operators,improve the safety factor of normal production of light hydrocarbon aromatization unit,reduce the comprehensive energy consumption of the unit,increase the output of the unit,and increase the efficiency of the enterprise.
