Removal and destruction of volatile organic compounds from gas streams

摘要

An apparatus and process for adsorbing volatile organic compounds, or VOCs, and efficiently regenerating adsorbent material in an emission control system. Flue gas, emitted from a combustion unit burning an outside fuel and desorbed VOCs, is humidified and cooled with a set of water injectors. The resultant humidified flue gas is directed through the adsorbent material, which is rapidly superheated without pressurization. A method for controlling the regeneration cycle of the emission control system includes at least three sensor configurations including a breakthrough sensor, a desorbed gas sensor and a flue gas temperature sensor.
