China Petroleum Network News (special reporter Meng Yan correspondent Tian Dejun) On August 23, after a week of optimization and debugging, the newly built liquid nitrogen tank of the Wanli Air Separation Plant of Liaoyang Petrochemical Company introduced liquid nitrogen and cooled the tank body. The liquid nitrogen tank project was officially completed and put into use.
The new liquid nitrogen tank project is one of the key projects of Liaoyang Petrochemical in 2022 as a safety hazard control project. A 1350 cubic meter storage tank, a liquid nitrogen pump and a supporting liquid nitrogen evaporation system will be added. The commissioning of this project can effectively cope with the abnormal situation of the air separation system and the peak demand of nitrogen for production, and greatly improve the emergency support capability of the device, which is of great significance to the air separation and air compression system.
Since the start of the project, Liaoyang Petrochemical has attached great importance to it and established a leadership and command group. The territorial units have organized professional research and repeated communication with manufacturers to formulate detailed construction plans. In addition, because the temperature of liquid nitrogen is as low as minus 196 degrees Celsius, improper operation can easily cause frostbite, suffocation and equipment damage. Liaoyang Petrochemical organized staff to write regulations and conduct staff operation training in advance to provide personnel guarantee for the stable operation of the system.
