Oxygen Plant is one kind of oxygen generation system producing oxygen. There are several types, one is small Oxygen Concentrator, producing small flow rate oxygen up to 20 liter per minute, it is mainly used at home. Another type is bigger flow rate oxygen plant, also using pressure swing adsorption technology. With this technology, oxygen with flow rate up to 200 Nm3/hr is suitable. For oxygen production flow rate from 200 to 3000 Nm3/hr, more suitable solution is using vacuum pressure swing adsorption technology. Its operation cost is more lower than PSA for this big flow rate oxygen production. For oxyen production bigger than 3000 Nm3/hr, normally use cryogenic technology. With this technology, oxygen production capacity can be 100000 Nm3/hr.
