Abstract [en]

The moist gas (2) is contacted with a hygroscopic medium at a temperature greater than the dew point during a regeneration step (3), then it is cooled to below its dew point during a condensation step (11) and then it is contacted with the hygroscopic medium from the regeneration step during a moisture removal step. - An INDEPENDENT CLAIM is also included for the heat recovery and pumping process apparatus comprising a regeneration device for concentrating the hygroscopic medium using the moist gas, a condensation device with heat exchangers (14) for cooling the gas and a moisture removal device with heat exchangers containing hygroscopic medium from the regeneration step.
