System and method for removing volatile vapors from containers

摘要

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.

主权项

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; andan 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; andan outlet to provide the recovered vapor capture medium to the vapor capture medium source.
