| Abstract: | Refrigeration process is applied to the chilled water at the lower stage of COG cooler,and open cycle is switched to closed cycle,so that water temperature is reduced by 10~ 15℃,meeting the process requirement. After comissioning and start-up, cooling water flow reaches 200m3 / h, CO2 emission is reduced by 12 000t / a,steam recovered by 69 120t / a,and water saved by 1 400 000m3 / a. The energy saving and emission reduction effect is remarkable. |
