Method for optimizing cold box and demethanizer system in sequential separation flow of cracked gas

Номер: CN0102175069A
Принадлежит:

The invention provides a method for optimizing a cold box and a demethanizer system in a sequential separation flow of cracked gas. The method solves the problem that the consumption of refrigerants of different temperature levels cannot be correspondingly adjusted together with the load change of cracked raw materials and the cracked gas in the prior art. Reasonable matching of the refrigerants of different temperature levels in the cold box and the demethanizer system according to the real-time and historical running data of an industrial device is realized, and ethylene loss of the cracked gas in the system is further reduced. The optimizing method can be universally applied to the refrigerant matching problem of the cold box and the demethanizer system in the deep cold separation flow of an ethylene device.
