The cryogenic oxygen production & oxygen&nitrogen production process introduces a low-pressure process into the air separation equipment, which reduces the energy consumption of the air separation and improves the safety of operation. Corresponding chemical software is used in process calculation and unit equipment design for process distillation calculation and structure calculation to ensure advanced and reliable equipment.

In order to meet the needs of the market, in addition to the production of conventional external compression air separation equipment, the company has also developed a series of internal compression air separation processes, which reduces the installation workload and equipment maintenance of the complete set of equipment.

The company designed and developed a skid-mounted purification system to minimize on-site piping installation time IF YOU HAVE ANY INTERSTS TO KNOW MORE INFORMATION, CONTACT US: 0086-18069835230
