A temperature swing adsorption process for removing a target component from a gaseous mixture containing at least one side component besides the target component, said process being carried out in at least one reactor, wherein said at least one reactor performs the following steps: (a) an adsorption step, comprising contacting an input stream of said gaseous mixture with a solid adsorbent and adsorption of target component from said input stream, providing a target component-loaded adsorbent and first waste stream depleted of the target component; (b) heating of the loaded adsorbent and desorption of at least part of said target component, providing an at least partially regenerated adsorbent and an output stream containing the desorbed target component; (c) cooling of said at least partially regenerated adsorbent, the process further comprising: said at least one reactor performs a preliminary heating step before said heating step (b), wherein during said preliminary heating step a gaseous product containing said at least one side component is released from the adsorbent, said gaseous product is submitted to a further adsorption step (a), said process is carried out in a plurality of reactors (101, 102, 103) and each reactor performs said sequence of adsorption step (a), preliminary heating step, heating step (b) and cooling step (c), and the gaseous product (113, 123) released from the preliminary heating step of each reactor (101, 102) is submitted to said further adsorption step (a) into at least one other reactor (103, 101) of said plurality of reactors, and wherein: the target component is carbon dioxide. $ The process is characterized in that: $ the heating step (b) is performed at a temperature not greater than 170 °C; the gaseous mixture is a flue gas of a methanol plant or of a urea plant; the carbon dioxide recovered from the flue gas is used as a feedstock for the methanol plant or urea plant.
