Statistics at the end of May showed that the industrial water plant at the Dushanzi Petrochemical Company's ethylene plant recovered more than 5,200 cubic meters of sewage per day. After the deep water treatment, it became desalinated water and was sent to the power station and water vapor device instead of new water, which saved water and protected the environment.
This plant utilizes advanced energy-saving equipment to promote clean production, recycle resources and reuse resources, reduce the proportion of high-energy-consumption and high-emission devices through technological innovation, and build a number of low-energy and low-emission devices to effectively save energy. Emission reduction laid the foundation.
According to statistics, this plant will send the recovered excess low-pressure methane, analytical gas, carbon dioxide and other waste gas to the methanol plant, so that the raw materials used in the methanol plant production are all recycled exhaust gas, saving 2.4 million cubic meters of natural gas per month and saving costs 250 More than ten thousand yuan. Compared with the same period of last year, the ethylene burning energy consumption, ethylene processing loss rate, polypropylene consumption of propylene, polyethylene consumption of ethylene, ethylene glycol consumption, ethylene consumption of new water, and other indicators have been significantly reduced, compared with similar devices in the country The level achieved the dream of creating a modern "new factory".
At present, this plant has made clear the "Twelfth Five-Year Plan" energy-saving emission reduction work plan and ethylene plant low-carbon circular economy work implementation plan, and put forward specific measures and key projects. A batch of energy-saving and water-saving measures such as reformation of cold feeds in cracking furnaces, recovery and utilization of surplus methane gas, recovery of condensate, and reuse of wastewater will be implemented to organize and coordinate the improvement of industrial water No. 2 plant, incinerator engineering and construction projects. Implementation.
