Process brief
This process is an internal compression air separation process integrating normal temperature molecular sieve adsorption purification, air pressurization booster, high and low-temperature pressurized turbine expander, full distillation of packed fractionation tower to produce argon. And is one of the most advanced internal compression air separation processes in the world.
Main features :
1. Uses liquid pumps to pressurize liquid oxygen, then converse LOX into GOX in the main heat exchanger.
2. Has a higher outlet pressure at the booster end of the expander so it saves more energy.
3. Has a secondary operating condition so the client has option of more fraction of LOX product.
