TSA process

A method for separating a raw gas comprising at least two components by means of a Temperature Swing Adsorption process, said method comprising:

• at least one adsorption step and at least one regeneration step, the cycle times of the individual method steps being configured for a design load value of said raw gas,
• wherein the cycle time of at least one method step is extended in the event of a drop below the design load value, and
• wherein the extended cycle time of said at least one method step is established according to the following formula:
• Cycletime—cu=Cycletime—sp*F_Load*F—PT*F—OP*F_Age
