System and method for removing volatile vapors from containers

Abstract

A system is configured to remove volatile organic compounds from a container. The system includes an enclosed contactor vessel having a first inlet to receive vapor containing volatile organic compounds from the container and a second inlet. The second inlet receives a vapor capture medium from a source. A contactor facilitates entrainment of the volatile organic compounds with the vapor capture medium while a first outlet recirculates treated vapor back to the container to effect a closed loop.

What is claimed is: 
     
         1 . A system comprising:
 A container containing volatile organic compounds (VOCs);
 an enclosed contactor vessel comprising:
 a first inlet attached to the container to receive the VOCs; 
 a second inlet attached to a source for a vapor capture medium; 
 a pump to draw vapor capture medium from the source through the second inlet; 
 
 an interface positioned to contact received VOCs with vapor capture medium received through the second inlet to form a VOC-vapor capture medium mixture; and 
 an outlet attached to a distillation column; 
 wherein the distillation column comprises;
 an inlet to receive the VOC-vapor capture medium mixture; 
 a separator to separate the VOC-vapor capture medium mixture into VOCs and recovered vapor capture medium; and 
 an outlet to provide the recovered vapor capture medium to the vapor capture medium source.
