【Learning from Others: Haichuan】A key project in energy recycling and precise management – the condensate recovery system at Jilin Petrochemical’s ethylene plant

Thread Content

On December 16, after half a month of trial operation, the key project related to the condensate recovery system at Jilin Petrochemical’s ethylene plant proved to be stable and reliable, capable of recovering 9 tons of condensate per hour. This achievement marks another step forward for the plant in terms of energy recycling and precise management. This system is designed for the systematic recovery of steam condensate generated by the plant’s processes and thermal piping networks; it covers an area of approximately 2.9 kilometers, with a total of 4 recovery units installed. By cooling the originally discharged steam condensate and feeding it into the heating water system, the original heating source is effectively replaced, thereby achieving a closed-loop utilization of energy. Calculations show that this project can generate over 200,000 yuan in annual benefits; by reducing energy consumption in production, it also cuts down on the use of fresh water for heat tracing, thereby improving both economic and environmental outcomes. To ensure the high-quality and efficient completion of the project, the factory organizes its operations scientifically and implements strict management. Since work began on October 10, taking advantage of the optimal period for construction, a 24-hour duty system and a leadership oversight system have been strictly implemented, with dual supervision by local authorities and the construction contractors. Through daily on-site inspections, close monitoring of key stages, and a weekly coordination meeting mechanism, risk prevention and control as well as process management are strengthened. The principle of \"no construction without safety guarantees, no operations without proper control\" is always adhered to, ensuring that the safety, quality, and progress of the project are all under effective control. The successful commissioning of this project is a concrete manifestation of the factory’s commitment to practicing the principles of ecological civilization and pursuing high-quality development. It not only optimizes the structure of energy utilization but also provides strong support for achieving the annual goals for energy savings and consumption reduction, as well as for continuously enhancing the company’s core competitiveness.
