METHOD FOR THE SEPARATION OF A GAS MIXTURE FLOW USING TEMPERATURE CHANGE ADSORPTION AND TEMPERATURE CHANGE ADSORPTION INSTALLATION

摘要

The invention relates to a method for separating a gas mixture flow, in which a temperature swing adsorption system (100) is used which has a number of adsorption units (A1, A2, A3), which are each operated in a first mode and a second mode, the first Operating mode comprises guiding the gas mixture flow (G) at least partially through an adsorption space of the respective adsorption unit (A1, A2, A3) and subjecting it to an adsorptive mass transfer with at least one adsorbent in its adsorption space, and the second operating mode comprises a first heat transfer fluid flow (W1 ) at a first temperature level through a heat exchange arrangement of the respective adsorption unit (A1, A2, A3) and to transfer heat from the first heat transfer fluid flow (W1) indirectly to the at least one adsorbent in its adsorption space. It is provided that the first mode of operation includes conducting a second heat transfer fluid flow (W2) at a second temperature level through the heat exchange arrangement of the respective adsorption unit (A1, A2, A3) and transferring heat from the at least one adsorbent in its adsorber space indirectly to the second heat transfer fluid flow (W1) to be transferred, and the adsorption units (A1, A2, A3) are each operated in a third operating mode, which includes a third heat transfer fluid flow (W3) at a third temperature level through the heat exchange arrangement of the respective adsorption unit (A1, A2, A3) and to transfer heat from the at least one adsorbent in its adsorption space to the third heat transfer fluid stream (W3). A corresponding temperature swing adsorption system (100) is also the subject of the invention.
