ABSTRACT:
The invention provides a process and apparatus for reducing the amount of energy which must be supplied to thermally activated separation processes such as fractional distillation, distillation, dehydration, or acid gas scrubbing. The reduction is accomplished by incorporating an absorption heat pump into the process such that the absorption heat pump accepts reject heat from (i.e. provides cooling to) the process and supplies higher temperature heat back to the process. The absorption heat pump causes the necessary temperature increase through the motive power of an external heat source applied to it, in contrast to the mechanical power source required by conventional heat pumps.
