HEAT REACTIVATED ADSORBENT GAS FRACTIONATOR AND PROCESS

摘要

A system for regenerating a desiccant bed having water adsorbed thereon to a desired moisture content comprising: a desiccant bed used to produce dry product gas having a first end and a second end; a source of feed gas, heated by a gas compression process fluidly connected to the desiccant bed wherein feed gas flows through the desiccant bed such that the heat present in the feed gas desorbs a portion of the moisture from the regenerating desiccant bed; and a source of cooling gas fluidly connected to the desiccant bed wherein the cooling gas flows through the desiccant bed in a closed loop such that moisture is desorbed from the bed as the desiccant bed cools and is carried back to the first end of the desiccant bed to provide additional cooling wherein moisture in the cooling gas is adsorbed.
