Abstract

See full text

In a compression process in a dynamic compressor having at least one first and one second compression stages, a first gas having a first molecular weight of less than 10 g/mol is compressed, at least one second fluid having a second molecular weight greater than 50 g/mol is mixed with the first gas to form a third gas to be compressed having a molecular weight greater than 10 g/mol, the third gas is sent to the first compression stage, the third gas is cooled in a first heat exchanger downstream of the first compression stage, where it is partially condensed, the partially condensed third gas is sent to a first phase separator to form a fourth gas having a lower molecular weight than the third gas and a first condensed liquid having a higher molecular weight than the third gas, the fourth gas is sent from the first phase separator to the second compression stage, the fourth gas compressed in the second compression stage is sent to cool in a second heat exchanger where it partially condenses, and the partially condensed fourth gas is sent to a second phase separator to produce a fifth gas having a lower molecular weight than the fourth gas.
