Qinghai Hongyuan Gas 8200 air separation project was put into operation

On March 20, 2021, through the joint efforts of all the contractors all staff, by my company for the qinghai hongyuan gas co., LTD., provide KDONAr - 8200/14000/280 type air separation unit smoothly success, for the industrial park in ganhe of qinghai province multiple chemical users with oxygen and nitrogen The set of device USES is the normal temperature molecular sieve adsorption purification air pressurization pressurization turbine expansion mechanism of cold internal compression process of oxygen, is my company independent research and development of the first set of 8.2 MPA grade of liquid oxygen compression device.

Due to the high pressure and low flow of oxygen products in this set of air separation device, which is rare in China, it is difficult to select the type of air supercharger and the organization of air separation process. After our company's analysis and calculation of various processes and in-depth communication with the supercharger manufacturer, both sides finally decided to adopt the six-level compressed air supercharger, which has small flow and high exhaust pressure.After single test run, combined test run and stable production, it is proved that the type selection and design of the supercharger are successful.Since stable production, the supercharger is suitable for a variety of operating conditions, and the energy consumption is low.
