| Abstract: | The refrigerating energy of ethylene cracking unit mainly consumes in former cold and demethanizer system.Through the analysis of the old separation device of Daqing ethylene cracking process,without changing the old separation feed quantity on the premise,we will optimize some of the former cold process,update the existing EC-401/402 expander and compressor units to recycle cold quantity,and then reach the purpose of saving energy and reducing consumption. |
