摘要： Provided is a method of producing gas hydrate at a low cost. An acid gas 3 is removed from a natural gas 1, and after dehydration 5 of accompanying water, part of heavy components 7 which do not produce gas hydrate 10 are separated and removed under a relatively high temperature. Moreover, the rest of the heavy components are taken out in a gas hydrate production step 9 together with an excessive portion of light components not contributing to production of the gas hydrate 10, as a fuel gas 11 which is used as a cooling source or a power source for a cooling system in the gas hydrate production step 9.

摘要： In a method of treating a hydrocarbon stream, such as a natural gas stream, a partly condensed feed stream (10) is supplied to a first gas/liquid separator (2), where it is separated into a gaseous stream (20) and a liquid stream (30). The liquid stream (30) is expanded and fed (40) into a second gas/liquid separator (3), and the gaseous stream (20) is split into at least two sub- streams (50, 70). A first sub-stream (50) of the at least two sub-streams is expanded, thereby obtaining an at least partially condensed first sub-stream (60), and subsequently fed (60) into the second gas/liquid separator (3). A second sub-stream (70) of the at least two sub-streams is cooled against a cold stream (120), thereby obtaining an at least partially condensed second sub-stream (90, 90a), which is fed (90, 90a) into the second gas/liquid separator (3) from which a gaseous stream (130) and a liquid stream (100, 100a) are removed. The at least partially condensed second sub-stream (90, 90a) may have a temperature of below -95 °C.

摘要： Nitrogen is removed from a liquefied natural gas feed (41) by a two stage separation in which the liquefied natural gas (41) is first fractionated (23) to provide a first nitrogen-enriched overhead vapour stream (46) and a nitrogen-containing bottoms liquid stream (19) and then at least a portion of said bottoms liquid stream (19) is fractionated (25) to provide a second nitrogen-enriched overhead vapour stream (36) that is of lower purity than said first overhead vapour stream (46) and a purified liquefied natural gas stream (50). Preferably, the first fractionation is conducted in a distillation column (23) refluxed (45) with nitrogen overhead (43) condensed in a condenser (24) located in a flash drum (25) in which the second fractionation is conducted. The provision of two nitrogen-containing streams (26, 36) of different concentration permits control of the nitrogen content of fuel gas for use in the natural gas liquefaction plant.

摘要： A hybrid condensation-absorption process and unit is disclosed for the recovery of olefins. A mixed-component stream containing hydrogen, methane and olefins is compressed and refrigerated against propylene refrigerant to partially condense the stream. The condensate is stripped of volatile components and fed to a fractionation unit such as a deethanizer. The volatile components stripped from the condensate and the non-condensed vapor from the mixed-component stream are fed to a solvent absorption unit to remove olefins which are absorbed in the solvent. The olefins-rich solvent is regenerated to recover olefins and lean solvent. The lean solvent is recirculated to the absorption unit. The olefins recovered from regeneration of the solvent are fed to the fractionation unit along with the pre-stripped condensate. Vapor from the absorption unit is cryogenically processed to recover a crude hydrogen product, a fuel gas product and residual olefins which can be recycled to the absorption unit. The hybrid process eliminates the need for low temperature (ethylene) refrigeration equipment, generally required by conventional condensation-based olefins recovery technology, and substantially reduces the solvent recirculation rate to the absorption unit and eliminates hydrogen expansion as compared to conventional absorption-based technology.
