Abstract:

Due to the special characteristics of the medium in cracking gas compressor, coking and fouling will occur inside the compressor, so that the compressor cannot be operated with design conditions, the compressor load will decrease, and the ethylene plant will shut down in case of severe fouling. This paper presents the phenomenon, causes and mechanism of coking, illustrates the hazards of fouling in cracking gas compressor with examples, introduces the monitoring and evaluation methods for coking during the operation of compressor, and analyzes a series of physical and chemical countermeasures for coking and fouling in cracking gas compressor.

Key words:  , cracking gas compressor, coking, vibration analysis, oil injection and water injection
