As title……
Strictly control the effect of the rough separation process and maintain a stable flow rate of gas entering the fine separation stage; the key is to manage the moisture content in the gas
We require that the sulfur content in the dew point remover be less than 0.1 ppm; strict control is applied to this parameter, and the gas supply is immediately cut off if the limit is exceeded. There is online analysis at the low-temperature methanol washing outlet. The sulfur capacity of the absorbent in the distillation tower should be tested regularly. The amount of high-pressure steam added should be appropriate
In addition to the regular regeneration of the degreasing tank, pre-hydrogenation can be regenerated using high-temperature steam, with strict control over the amount of hydrogen sulfide entering and the ammonia content
