A method for storage and transport of LPG on LPG carriers, in particular two cargoes of different LPG types on same shipment, having reliquefaction units (300, 400) in which vaporized gases are condensed and then returned into at least one cargo tank (100) for the respective LPG cargo type. The method is further comprising: using the reliquefaction units (300, 400), at a minimum one running, as to condense vapor from the first cargo type; passing the condensed vapor through a heat exchanger (500); simultaneously flowing vapor from the second cargo type through the heat exchanger (500) as to condense vapor by means of heat exchanging with the condensed vapor; and returning the condensed vapors leaving the heat exchanger back into the respective cargo types. The present invention is also disclosing a system for storage and transport of LPG on LPG carriers.

The present invention relates to an apparatus for pressurizing delivery of a low-temperature liquefied material, and more particularly, to an apparatus for pressurizing delivery of a low-temperature liquefied material, which can convert the low-temperature liquefied material into a high-pressure gas and easily deliver the gas without causing changes in a composition and flashing phenomenon.

Disclosed is a BOG reliquefaction system. The BOG reliquefaction system includes: a compressor compressing BOG; a heat exchanger cooling the BOG compressed by the compressor through heat exchange using BOG not compressed by the compressor as a refrigerant; a pressure reducer disposed downstream of the heat exchanger and reducing a pressure of fluid cooled by the heat exchanger; and a second oil filter disposed downstream of the pressure reducer, wherein the compressor includes at least one oil-lubrication type cylinder and the second oil filter is a cryogenic oil filter.

The invention relates to a device for degassing liquid hydrogen circulating in a circuit comprising a liquid inlet pipe, a pump feed pipe receiving a portion of the liquid arriving via the inlet pipe, and a return pipe receiving another portion of the liquid arriving via the inlet pipe, the liquid inlet pipe, the pump feed pipe and the return pipe communicating with a vertical degassing chamber and the cross-section of the vertical chamber at the level of the mouth of the inlet pipe for the arrival of the liquid in the vertical chamber is greater than the cross-section of the inlet pipe for the arrival of the liquid at its mouth with a ratio between these two cross-sections greater than or equal to two, the degassing device comprising a deflector arranged in the vertical chamber opposite the mouth of the inlet pipe.

Methods, apparatus, systems, and articles of manufacture are disclosed herein that include a cryogenic pump system comprising: a cryogenic liquid tank; a cryogenic pump including a suction adapter, the suction adapter connected to the cryogenic liquid tank via a liquid supply line and a gaseous return line; and a phase separator connected downstream of the cryogenic liquid tank and upstream of the cryogenic pump, the phase separator including a filtration structure integrated into the liquid supply line to separate vapor from cryogenic liquid, the phase separator connected to the gaseous return line to direct the vapor to the cryogenic liquid tank.
