PSA Equipment Set
Technology Overview
1. PSA is a gas separation technology with low energy consumption. PSA technology requires pressure to be within 0.1~2.5MPa, allowing a wide range of pressure changes. Some source gas with pressures such as shift gas and released gas from synthetic ammonia can satisfy PSA requirements without being repressurized. To process such source gas, consumption is low and only includes lighting, power and air supply of instrumentations. Pressure loss of such PSA plant is very small, usually no more than 0.05MPa;
2. PSA plant can produce high purity gas product, e.g.: PSA hydrogen production plant can purify 98.0~99.999% hydrogen;
3. The process of PSA technology is very simple, without preprocessing system. One or two steps can achieve separation of a variety of gas, and can separate various source gas of complex components. PSA has strong adsorptive capacity of water, sulfide, ammonia, hydrocarbon, etc.;
4. PSA plant is highly automated and is controlled by computers, and is easy to operate. PSA plant can be put into operation in a very short period of time after it starts, and yield qualified products.
