Tianjin Chemical Research and Design Institute "industrial circulating cooling water-saving technology development and application of demonstration devices" project, a few days ago through the China Petroleum and Chemical Industry Association organization of scientific and technological achievements identification. According to the briefing, the project is a national "Tenth Five-Year Plan" major scientific and technological breakthrough plan project. It is a systematic integration of multiple disciplines, such as chemistry, physics, biology, and automation. The device can be widely used in metallurgy, chemical engineering, power generation, petrochemical, textile, and oil fields. Wait for all water departments. The successful implementation of this project has greatly promoted the development of Tianjin Chemical Research and Design Institute itself. At the same time, the results were applied in 34 companies such as Tianjin Petrochemical Company's Ethylene Plant. The results show that in the three years accumulated 120 million tons of water, creating economic benefits of 350 million yuan. At present, this technology has obtained 5 national invention patents, which has opened up new ways for the water-saving work of China's industrial systems.
