Abstract: Method of liquefying a mixture of gas rich in methane by performing an auxiliary cycle and a main cycle in which are used an auxiliary and a main refrigerating fluid of several components. In each cycle are performed the compression, cooling, liquefying and sub-cooling of the refrigerating fluids in counter-flowing relationship with themselves after expansion-vaporization in a heat exchanger. The gas to be liquefied is cooled in parallel with said main refrigerating fluid which has been pre-cooled in the auxiliary cycle. Pre-cooling of said gas is performed in an exchanger cooled by the refrigerating main fluid after its expansion-vaporization in said heat exchanging column of said main cycle and before its re-compression.

Abstract: The invention is a process for the denitrogization of a liquefied natural gas (LNG) comprising methane and at least 2 Mols. of nitrogen. The process is distinguished in that the LNG is introduced into the process as a liquid and is subject to an indirect heat exchange to cool the liquid and a further decompression before introduction into fractionation of column. A portion of the liquid flowing in the fractionation column is withdrawn and utilized to cool the LNG feedstock and is returned to the fractionation column at a level lower than the level from which it was withdrawn. The decompression of LNG feedstock comprises at least one dynamic decompression and at least one static decompression.

Abstract: The process consists in successively separating increasingly heavy petroleum cuts at the head of a plurality of columns CO1, CO2, CO3 and Cl0 of a first series of columns which feed individually each column of the second series. The column CO7 is a gasoline stabilizing column which feeds an installation for fractionating light petroleum gases. The column CO4 is a gasoline fractionating column. The columns CO5 and CO6 are columns for separating petroleum naphthas from kerosine. The atmospheric residue collected at the bottom of the column Cl0 is processed in the vacuum distillation column Cl2 and the residue from this column is processed in the second vacuum distillation column Cl3 after reheating in a furnace.By carrying out a succession of progressive separations performed in a series of columns of small volume, more efficient utilization of the recovery heat is achieved.
