这里介绍的是多级往复式压缩机的一种实用控制方案,使用在我厂煤油加氢装置的氢气压缩机上。为便于系统分析,先简单说明一下工艺过程与要求。整个系统如图所示(图中各段的冷却器未画出)。该氢压机为五级,其任务是将送到加氢反应系统的氢气压缩到加氢反应所需压力63kg/cm~2。进入压缩机的氢气有三路:一路为高压分离出来的循环氢;一路为脱氢装置产生的氢气;一路为制氢车间的电解氢。由于三路氢气源的压
Here is a practical multi-stage reciprocating compressor control program used in our hydrogenation plant kerosene hydrogen compressor. For the convenience of system analysis, a brief description of the process and requirements. The whole system as shown (the figure of the cooler section is not shown). The hydrogen press is five-stage, the task of which is to compress the hydrogen supplied to the hydrogenation reaction system to the pressure 63 kg / cm ~ 2 required for the hydrogenation reaction. Hydrogen into the compressor has three ways: all the way to high-pressure separation of the recycled hydrogen; all the way for hydrogen dehydrogenation device generated; all the way for the hydrogen production plant hydrogen. Due to the pressure of the three hydrogen source
