ABSTRACT:
The system and method for recycling the compress heat generated at a bio-gas treatment plant that includes the assembly of a heat exchanger at each stage of compression designed to utilizing all of the gas flow and to harvest the heat in gas delivered to the air exchangers. After the heat is harvested, it is then conveyed either as hot air, or as a hot liquid, to a jacketed vessel containing media that requires regeneration or stripping of harmful VOCs picked up during the purification of contaminated landfill or municipal digester gas. The harvesting and conveyance of the heat of compression of the gases to a jacket around the vessel interior (indirect contact) and simultaneously heating the vessel interior containing the spent media through hot gas from another source (direct contact), reduces the heat-up time. This also reduces the overall the cycle time between the contaminant pick-up step and contaminant stripping step in regenerable treatment systems.
