摘要:

通过动态仿真技术分别模拟了大回流、逐级回流和末级回流三种回流方式应用在C3/MRC液化工艺中丙烷压缩机的适应性。在此基础上分别添加高压处控制和低压处控制,比较了当改变控制器的设定值时丙烷系统所受到的影响以及控制器的响应速度。结果表明:丙烷压缩机采用逐级回流高压处控制的方式可以满足液化工艺所要求的良好的稳定性与较快的响应速度。

Abstract:

The flexibility of three reflux modes including overall reflux, gradual reflux and last stage reflux for propane compressor in C3/MRC liquefaction process is simulated respectively by dynamic simulation, on which basis high pressure control and low pressure control are added, respectively. In this way, the influence on liquefaction process and the response speed of the controller by changing the settings of controller can be analyzed. It is indicated that the high pressure control of gradual reflux can meet the demand of better stability and faster response in liquefaction process.

Key words: liquefaction process, C3/MRC, compressor, control mode, dynamic simulation
