Research on Explosion Curve Control Strategy of Acrylic Acid Production Process Based on SIS
In order to control the explosion curve of the acrylic acid reactor,which is a more dangerous process in chemical applications,and to avoid the risks and hazards of explosion accidents caused by operating points touching the explosion curve during its production process,a control strategy with high reliability,fast response time,and high availability has been investigated.Through the dynamic adjustment of environmental conditions and parameters,the explosion curve of this complex process for effective management.According to the range of the explosion curve and the calculation of the operation point,the system monitors the data of the explosion curve and the preset safety limits in real time by establishing a mathematical model and introducing control variables and constraints.The corresponding reaction control strategy is formulated to realize timely intervention and regulation of the explosion process.Simulation test results prove the effectiveness and safety of the control strategy.The safety instrumented system(SIS)can be used to better control the explosion curves in the acrylic acid production process.
