NOVELTY - The system (10) has a vessel (13) that contains activated carbon fiber adsorption cartridges (14). Valves (16,18) are provided for controlling gas flows into and out of the vessel. A controlled power supply (26) is provided for heating the activated carbon fiber adsorption cartridge to set points for desorption and adsorption cycles. An active condensation loop actively cools or compresses desorption gas stream to liquefy low boiling point gases.    USE - Gas purification system for recovery and liquefaction of low boiling point gases e.g. organic and inorganic gases such as methane, propane, isobutane, carbon dioxide, ammonia and chlorofluorocarbons.    ADVANTAGE - The gas purification system can increase the sustainability and economics of such industrial processes. Low boiling point gases are adsorbed with a heated activated carbon fiber material maintained at adsorption temperature during adsorption cycle. The active condensation loop has condenser that reduces temperature of desorption gas stream to the dew point of predetermined low boiling point gas. The low boiling point inorganic and organic gases are captured by the gas purification system, and can be re-used in the manufacturing process of industry if desired. The isobutane gas is important in the production of packaging materials.Recycling and using the dilute gases from the effluent stream avoids the need for thermal distribution of the dilute gases in the effluent stream. The recycling process offers potential cost benefit, and avoids the cost of thermal destruction including mitigation of resultant green house gas and ozone precursors, and reduces the need for raw material for input to the system. The capturing of carbon dioxide reduces the amount of emission into the atmosphere.
