ABSTRACT:
In a process for producing chemical substances comprising steps of cooling, condensing and solvent-absorbing the reaction product gas having a high temperature formed in a reactor, an absorption type refrigerator or an absorption type heat pump is driven by using, as the driving source, a heat source having such a temperature as not to be advantageous for the heat exchange in the process, which heat source has been taken out of the steps of cooling the reaction product gas, condensing it or solvent-absorbing it to obtain a refrigerant or a hot water having a temperature higher than the temperature of the heat source, and the refrigerant or the hot water is used as a cooling source or a heating source in the steps comprised in said process for producing chemical substances.
