Abstract
A gas concentration method and a gas concentrating plant, especially for the separation of oxygen out of air by means of adsorbtion. According to the invention air is first compressed by means of a compressor (1) and dried by means of a dual tank moisture adsorbing unit (14, 15) in order to achieve for the gas adsorbing unit (34', 35) feed air, dew-point of which is about -40 DEG C. The major part of the oxygen-rich gas coming out from the adsorption unit is led forward and the lesser part of said oxygen-rich gas is recycled unit in order to regenerate the adsorbtion unit by removing the nitrogen-rich gas bonded to the adsorption material of the adsorption unit. Said gas flows: compressed and dried feed air flows to adsorption units (14, 15; 34', 35), oxygen-rich gas flows to be recycled and led forward, nitrogen-rich gas flow to be removed from the adsorption unit (34', 35), are controlled and regulated by means of pneumatically operating regulation and control elements (10...13, 28...31, 36, 37, 52...64), whereby the separation of a gas component, advantageously oxygen out of air, is reliably and safely carried out also in humid, cold and/or explosion risky conditions.
