Refrigerated vapor recovery system

摘要

Volatile vapors are removed from a storage vessel by establishing a flow of a stream of volatile vapors from the storage vessel and directing the vapor stream through a heat exchange module for condensing a portion of the vapors in the stream flowing through a cooled heat exchange condensers in the heat exchange module. The uncondensed vapors in the vapor stream are then directed to a carbon adsorption module including a pair of carbon adsorption units. The vapor recovery system also provides a means of desorbing a carbon adsorption unit that approaches its capacity for adsorbing volatile organic molecules and recycling the desorbed vapor stream through a cooled heat exchange condenser to convert the volatile organic material into a liquid state that may be sold as a product or utilized as a raw material rather than being combusted or otherwise disposed of in the atmosphere.
