万立制氧机组增加氮气产量实践

在分子筛流程中,为了将制氧机组中空气预冷系统水冷塔的氮气替换出来并送入管网,采取了增设水冷机组冷却经污氮冷却的低温水的措施。采取措施后,出塔水温在不使用氮气的条件下达到了设计要求,满足了生产工艺条件,从而增加了氮气产量。

Practice of Increasing Nitrogen-manufacturing Capacity by 10 000 m3/h Oxygen Making Machine Unit

In order to substitute for the nitrogen in water-cooling tower to the air precooling system in oxygen making machine unit based on the molecular sieve process and then supply the nitrogen into the pipe network, the measure of additionally installing the water cooling machine unit for cooling the low temperature water cooled by the crude nitrogen was taken. After the measure was taken, the temperature of the water drained out of the tower without needing the nitrogen for cooling can meet design requirements and satisfy the conditions for productive technology. And therefore the capacity for manufacturing nitrogen was increased.
