Abstract
The invention relates to a method and to a device for performing a process (P) having at least one heat-consuming process step (F). A first fluid (2), which arises in the process and contains acid gases and water vapor, is cooled indirectly against a second fluid (7), an acidic condensate thus being formed. The invention is characterized in that the first fluid (2) is cooled in at least two successive steps (E1, E2), between which heat for use in the heat-consuming process step (V) is indirectly drawn from the second fluid (10).
