The present invention relates to a method for transferring heat to a target process in a chemical production plant, the method comprising (i) providing a first process stream (1) having a temperature T1; (ii) transferring heat from a chemical conversion process, from a physicochemical process, from ambient heat, or from a combination of two or more thereof, to the first process stream provided in (i), for obtaining a heated first process stream (3) having a temperature T2, wherein T2>T1; (iii) conducting the target process with the heated first process stream obtained in (ii); wherein the target process is different from the chemical conversion process, from the physicochemical process, or from the combination of the chemical conversion process and the physicochemical process from which heat is transferred according to (ii). According to the method of the present invention, a coefficient of performance of greater than 1 can be achieved.
