<p>"PROCESS FOR THE COOLING OR HEATING OF A GAS" In the heat exchange of gases, e.g., flue gas, to cool or heat same, the gas is contacted directly with a heat transfer liquid in a first direct-contact heat exchanger, the gas is then subjected to a temperature dependent process step, e.g., SO2 absorption with a physical solvent, and the resultant process gas is reheated or recooled in a second direct-contact heat exchanger using the change in enthalpy that the heat transfer liquid has undergone in the first direct contact heat exchanger.</p> |
