ABSTRACT:
A system for recovery of adsorbed gas remaining in a used storage and dispensing vessel containing sorbent material having residual sorbate gas thereon, when the vessel is taken out of service, in which the used storage and dispensing vessel is coupled in flow communication with at least one fresh storage and dispensing vessel containing sorbent material therein having sorptive capacity for the residual sorbate gas. The fresh vessel is maintained in a first zone and the used vessel is maintained in a second zone, at temperature and/or pressure conditions relative to one another that cause the residual sorbate gas to desorb from the sorbent material in the used storage and dispensing vessel and flow into the fresh storage and dispensing vessel for sorption of the residual sorbate gas on the sorbent material in the fresh storage and dispensing vessel. The system of the invention permits a substantially complete recovery of residual sorbate gas that would otherwise be lost when the used storage and dispensing vessel is taken out of service and decommissioned.
