摘要： The method provides liquefaction of a natural gas by carrying out the following stages: cooling the natural gas; feeding the cooled natural gas into a fractionating column so as to separate a methane-rich gas phase and a liquid phase rich in compounds heavier than ethane; and liquefying the methane-rich stream so as to obtain the liquid natural gas. According to the invention, the operating conditions in the fractionating column are so selected that said liquid phase comprises a molar proportion of methane ranging between 10% and 150% of the molar proportion of ethane.

摘要： The liquefaction method provides fractionation of the natural gas with ethane recycle in order to enhance propane recovery and to increase the critical pressure of the gas to be liquefied.The natural gas is partly liquefied by cooling in E1, then separated in fractionating column 2 into a methane-rich stream and a stream rich in hydrocarbons heavier than methane.The methane-rich stream is partly liquefied in 3, then the condensates separated in drum 4 are recycled to the top of column 2 through line 7. The gas fraction from drum 4 is liquefied in exchanger E2 to produce the liquefied natural gas.The stream rich in hydrocarbons heavier than methane is separated in the deethanizer into an ethane-enriched fraction and heavier hydrocarbons.According to the invention, the ethane-enriched fraction is at least partly liquefied, then part of the liquefied ethane is recycled to separating drum 4 or reflux line 7.

摘要： A fluid distributing-collecting process using a device for bringing fluids and solids into contact comprises several distributor plates and several panels for mixing, distributing or extracting fluids. The system for practicing the method includes at least one level one chamber in connection with the outside of said device with at least one hose and, at least one level two chamber that is linked with the level one chamber and that comprises one or more connecting hoses of a selected length that are arranged in at least one zone. The zone is identified relative to an angle &agr; relative to a radius of a plate and corresponds to a given angle sector, whereby hose lengths, angle &agr; and the angle sector are selected in accordance with the process so that injected fluid arrives approximately at the same time on all of the panels of the same plate. This process is used for separation of paraxylene in a simulated moving bed.
