Applications of pressure swing adsorption technology

Pressure Swing Adsorption (PSA) technology represents an important separation process for gases. In addition to typical integration of PSA units in the plant structures (e.g. combination of steam reformer and H-2-PSA) more complex combinations are possible to optimise the overall process performance. The PSA process itself is strongly influenced by certain process parameters like tail gas pressure, number of pressure equalisation steps etc. PSA units can handle growing throughputs meanwhile they are getting specifically smaller. Sophisticated control systems enhance the performance, flexibility and automation.
