Abstract:

 In view of the surplus low-pressure saturated steam in a newly-built aromatics complex, a steam compressor is used to solve the problem of poor utilization of low-pressure steam. By comparing the characteristics of low-pressure steam power generation, refrigeration, heat pump and compression, the steam compression technology is selected to recycle the low-pressure steam. With good economic benefits and short payback period, this technology is expected to be further promoted in the future. It also provides a new way of thinking for the steam balance optimization, energy saving and consumption reduction of refining and petrochemical enterprises.
