Oxygen Station for Oxygen-enriched Top-blowing Project of Jinchuan Group Co., Ltd.
Design project, located in Jinchang City, Gansu Province, which is under design.
Two sets of 30000 Nm3/h air separation oxygen generating facilities will be constructed in two phases: one set of oxygen generating unit with the oxygen pressure of 1.4 MPa and flow rate of 30000 Nm3/h in the first phase; and one set of oxygen generating unit with the oxygen pressure of 0.05 MPa and flow rate of 30000 Nm3/h in due time of second phase as required by the oxygen consumption schedule.
The scope of process design includes: main plant building of oxygen station within the enclosure wall; outdoor air separation area, molecular sieve purification area, liquid storage area; perlite storehouse, circulating cooling water plant building, as well as pipeline network and support of corresponding input and output products, etc.
Oxygen generating process (first phase): it is a process adopting the full-packed tower technology and full-rectification hydrogen-free argon-generating, which achieves the adsorption by full low-pressure molecular sieve, internal compression of oxygen, middle-pressure expansion of air and entry of expanded air into lower tower, with advantages of reliable technology, advanced process, easy operation, safety and low consumption.
Oxygen generating process (second phase): it is an external compression process adopting the structured packing and full-rectification hydrogen-free argon-generating, with the device purifying air by molecular sieve and equipped with the supercharged expander.
