Abstract

Plants in which used a pressure-swing adsorption (PSA) are widely applied for maintenance of various consumers by oxygen or nitrogen. Their productivity depends on air' temperature which are intake in the compressor. The choice of the compressor is made for operating conditions of PSA-plant in nominal mode. Therefore PSA-plant works in off-design behavior modes at change of temperature of air. Its productivity and other characteristics at operation in such modes can essentially change. It is shown how to provide an effective work of PSA-plant in off-design behavior modes with little change of characteristics. For this purpose is offered to enter in actigram the periods of stops of a cycle. The design procedure of duration of these stops is resulted, the general requirements to choice of the compressor and volumes of receivers are stated.
