我厂各装置的含硫污水是在压力下直接送往含硫污水双塔汽提装置储罐的。由于压力的降低,溶于水中的烃类气体释放出来,并携带一部份硫化氢气体排入大气,严重地污染了环境。特别是液化气系统操作不稳定时,液化气随污水进入含硫污水储罐,大量气体从罐顶排出,既污染环境又不安全。为解决上述问题,于1985年设计建成了“含硫 The sulfur-containing sewage of each plant in our plant is directly sent to the double-tower stripping device storage tank of sulfur-containing sewage under pressure. As a result of the pressure drop, the hydrocarbon gas dissolved in water is released and carries part of the hydrogen sulfide gas into the atmosphere, seriously contaminating the environment. In particular, when liquefied gas system is not operating smoothly, liquefied gas enters the sulfur-containing sewage storage tank along with the sewage, and a large amount of gas is discharged from the tank top, which is not only polluting the environment but also unsafe. In order to solve the above problems, in 1985, designed and built a "sulfur
