1995年9月28日7:40分左右,我厂某车间山梨醇生产线上的氢气循环压缩机突然停机、损坏并造成全线停车。该循环压缩机属卧式单级活塞往复式压缩机,型号为PH3000/1,它与五台氢化反应器串联成一个小循环系统。带夹套的氢化反应器内的物料主要有葡萄糖、碱液(碳酸钠)、氢气、镍催化剂和山梨醇。其中过量氢气经冷却送入循环压缩机,将氢气压力提高到 At about 7:40 on September 28, 1995, the hydrogen cycle compressor on the sorbitol production line of a certain plant in our factory stopped suddenly and damaged and caused a full stoppage. The circulating compressor is a horizontal single-stage piston reciprocating compressor, model PH3000 / 1, it is in series with the five hydrogenation reactor into a small circulation system. Materials in jacketed hydrogenation reactors are mainly dextrose, lye (sodium carbonate), hydrogen, nickel catalyst and sorbitol. The excess hydrogen is fed to the recycle compressor by cooling, raising the hydrogen pressure to
