| Abstract: | In SINOPEC Anqing Company, the low-temperature waste heat recovery system has been successfully revamped to recovery the low-temperature waste heat from atmospheric-vacuum distillation unit, FCC unit, delayed coker by hot media water so that it can be utilized as the heat source of bottom reboilers of depropanizer and deethanizer of LPG fractionation unit. 28.5 t/h of low-pressure steam is saved and annual e-conomic benefit from saving is 24.42 million Chinese Yuan. |
