Sinopec Changling Refinery: Production equipment "drank" mountain spring water 4 days ago Original title of Xinhuanet: Sinopec Changling Refinery: The production device "drinks" mountain spring water and starts the low-power transmission equipment. The 700,000 tons/year reforming unit of Sinopec Changling Refining and Chemical Company can "drink" more than 20 tons of mountain spring water per hour. Up to now, the company's production system has used more than 10 million tons of mountain spring water, which has played a positive role in reducing production water consumption and protecting water resources. Changling Refining and Chemical, located on the bank of the Yangtze River and in the mountainous area of ​​northern Hunan, has always regarded protecting the ecological environment as the prerequisite and foundation for enterprise development and construction. The company's refining operation area is surrounded by more than 1,000 acres of mountain forests that are more than 50 years old. In order to keep the mountains and forests evergreen, the company has increased its efforts in environmental governance year by year, insisting that when profits, output, progress, costs, etc. conflict with environmental protection requirements, they must give way to environmental protection. Any investment required for environmental protection will not be done, and anything that does not meet the requirements of environmental protection will not be done. Anything that is at the expense of environmental protection, pollution and damage to the environment will not benefit at all. “An acre of forested land can store 20 tons more water than an acre of non-forested land. The company has made thousands of acres of mountain forest evergreen all year round, and nature will definitely feed the company back. ”Said He Zhixin, Greening Department of Changling Refining and Chemical Public Service Center. The company's 8-million-ton refining projects are all built against mountains. There is a small flood drainage ditch not far from the boundary of each device. The mountain spring water in the ditch flows continuously all year round. After multiple batches of laboratory tests and data theoretical research and demonstration, the mountain spring water in the ditch of the installation is cool, transparent and has no impurities. The water quality is better than the fresh water in the installation pipe network, and it can be used as production water for the installation. To this end, Changling Refining and Chemical has set up a technical team to initiate projects, organize processes, equipment and other majors to tackle technical issues in all aspects of mountain spring water recycling. They collaborated with many parties, and after on-site investigation, technical demonstration, and feasibility analysis, they built a large-scale clean mountain water recovery device in the middle and lower reaches of the main flood drainage ditch in the refining operation area to timely recycle the mountain spring water in the drainage ditch. After completing basic purification, they transported the cooling water system of the production unit for comprehensive utilization. At the same time, the company designed and built a micro overflow dam in the flat area of ​​some installations to intercept or reduce the overflow of mountain water to downstream installations, reduce the "washing" of the installation area by mountain water, reduce the pollution of downstream water bodies by various toxic and harmful substances such as oil and alkali, and improve the cleanliness of the clean water in the main drainage ditch. The micro overflow dam is equipped with a multi-layer filter. By turning on the small pump, the clear mountain spring water can be directly injected into the production device, allowing the device to taste the sweet mountain spring water given by nature. Changling Refinery has also increased the construction of "rainwater-sewage separation" projects in various production areas, implemented "cleaning and sewage diversion" responsibility management at the installation site in a grid-connected format, strictly divided oily and salty sewage and clean rainwater, and entered the water treatment device through different channels to ensure that slightly contaminated rainwater falling into the device during rainy periods does not enter the device side ditch, thereby improving the operating efficiency of the mountain water recovery device in the main drainage ditch and the total amount of clean water recovered. At present, Changling Refining and Chemical's general drainage ditch clean water recovery device recovers about 1 million tons of clean water every year. A single device's side ditch micro-overflow dam recovers more than 20 tons of mountain spring water per hour, which reduces the overall operating cost of the company and forms a water resource recycling protection system of "comprehensive utilization-reduced water extraction-nature feeds back", and the ecological environment of the company's location has been effectively managed.
