What are the Advantages of VPSA Oxygen Generation Technology Compared with Cryogenic Process?
For small to medium-sized plants (<20,000 Nm3/h), VPSA oxygen generation technology has the following advantages over conventional cryogenic air separation process:
1) Economically, VPSA oxygen-generating equipment has smaller investments and lower operation costs.
2) The VPSA oxygen generation process is simpler, with fewer equipment components and precision, higher degree of automation, and lower requirements for the operators.
3) In terms of operating conditions, the VPSA oxygen plant is operated under normal temperature and pressure, the time required for start-up and shut-down is shorter (≤30 minutes). The unit can be operated either intermittently or continuously, with a wider range of load regulation.
4) In operation and maintenance, no hydrocarbons are accumulated in the VPSA oxygen-generating process, with no possibility of explosion. The low precision of the mainframe makes it simple to maintain, and the requirements for valve sealing are not harsh, so the failure rate is lower and easier to deal with timely.
