Optimization and Application of Extraction System Cold Water Circulation Process

LI Jin-feng;CHAI Feng-yun;HU Long-xiang;SUN Wu;ZHANG Chen;YANG Meng;Natural Gas Processing Plant of Zhongyuan Oilfield Puyang;  
Aiming at the high energy consumption of the cooling system of the production process of the second gas treatment plant of the natural gas processing plant. By analyzing the production process status of the extractive distillation system, combining the actual field production with the theory, the possibility of replacing the cold water of the chiller with circulating water was determined, and the optimization process of the cold water cycle was proposed, and the existing process was modified.The application shows that through the process transformation, the treatment plant stops the chiller throughout the year, and uses the circulating water instead of the cold water to provide cold water for the T-308 overhead condenser. The annual electricity consumption is 242,400 kWh, and the electricity cost is 145,440 yuan.The original intention of saving energy and reducing consumption was realized, and the efficiency of resource utilization was improved.
