Abstract: Methods and systems for treating volatile organic compounds (VOCs) generated in a hydrocarbon treating process are disclosed. An effluent stream containing the VOCs, as well as carbon dioxide (CO2) is combined with hot exhaust gas from a turbine and provided to a waste heat recovery unit (WHRU). The WHRU is adapted to contain a catalyst bed containing oxidation catalyst capable of effecting the oxidation of the VOCs. The temperature of the catalyzing reaction can be tailored based on the position of the catalyst bed within the temperature gradient of the WHRU. The methods and systems described herein solve the problem of effecting the removal of VOCs from the effluent. Heating the CO2-containing effluent in the WHRU also lend buoyancy to the effluent, thereby facilitating its dispersal upon release.

Abstract: A modular adsorption plant comprises one or more transportable cargo containers which hold the various adsorbent beds, pumping apparatus and so on which comprise the plant. The containers are easily transportable, and may be rapidly assembled in modular fashion to produce a large capacity plant.
