Period of returnOnboard reliquefaction of boil-off gas (BOG) generated due to heat in-leak in LNG carrier ships saves its calorific value and protects environment. Direct cryogenic liquefaction cycles, which use BOG as the working fluid, have the potential to reduce power and size of the ...
1). The residual gas is used for heating purposes for hydrogen production. In industrial practice, the Claude process did not live up to its promises due to technical problems caused by the severe operating conditions [24]. For example, the use of hyper-pressures also results in high partial...
TECHNICAL FIELD OF THE INVENTION The present invention relates to a method and device for improving the thermal performance of a nitrogen refrigeration cycle. BACKGROUND OF THE INVENTION Gas liquefaction is a known process used to liquefy gases and commonly employs a nitrogen refrigeration cycle to ...
pumping sites will no longer require the first delivery after the transport is filled from the liquid cryogen source, such as a liquefaction plant. This relieves a major constraint on the distribution system that confines delivery order, the miles driven, and value of product after the first ...
Hydrostatic gas compressor i.e. variable volume closed container, for adiabatic liquefaction of gas based on Claude method, has compression chamber walls made of non-freezing and non-destructive, expandable and/or deformable materialThe compressor has a compression chamber whose walls are made of non...
Several methods can be used to obtain the low temperatures required for liquefaction of gases. The process of cooling or refrigerating a gas to a temperature below its critical temperature so that liquid can be formed at some suitable pressure, which is below the critical pressure, is the basic...
