Abstract:

In view of the shortage of ultra-high pressure steam driven by the turbine of cracking gas compressor in the No. 2 ethylene plant in Dushanzi, the ultra-high pressure steam generation system, the ultra-high pressure steam transmission and distribution system and the ultra-high pressure steam users were investigated, and some optimization measures were put forward and implemented during the overhaul in 2019. These measures not only reduced the loss of ultra-high pressure steam and the consumption of medium pressure steam, but also reduced the consumption of fuel gas and improved the thermal efficiency of cracking furnace.

Key words: ultra-high pressure steam, insulation and valve internal leakage loss, optimization
