A system and apparatus for condensing boil-off vapor from a Liquified Natural Gas (LNG) container are disclosed. A system for condensing vapor includes the steps of providing contact area within a condenser vessel, directing vapor to the condenser vessel, providing a condensing fluid and a pump fluid, directing the condensing fluid to the condenser vessel, varying the flow of the condensing fluid to control the pressure in the vessel, contacting the vapor with the condensing fluid to create a condensate, and combining the condensate and the pump fluid. An apparatus for condensing vapor includes a vessel, a liquified gas input to the vessel, control means on the liquified gas input for varying a first liquified gas stream to control the pressure in the vessel, a vapor input to the vessel, means for condensing vapor in the vessel, and means for combining condensed vapor with a second liquified gas stream. |
