AIR ADSORPTIVE SEPARATION PROCESS

摘要

The invention concerns an improved method for the separation of oxygen or nitrogen from air according to the vacuum swing adsorption (VSA) process or pressure vacuum swing adsorption (PVSA) process using a vacuum pump system optimized for the desorption of the adsorbed air component. This system comprises a radial flow compressor and a vacuum pump operating according to the displacement principle, in particular a rotary piston compressor.
