A method for the transportation and separation of gas from liquid and solid media in one or several stages in a manner so that the pressure in the gaseous phase from an early separator stage or from another gas deposit is utilized for the transportation of the fluids produced in subsequent separator stages. Gas which is separated off at high pressure in an early separator stage or gas from another gas deposit is led into a separator which has carried out separation at a lower pressure. The high pressure gas forces out the ready separated fluid which is present in the separator receiving the high pressure gas. The separator stage which receives high pressure gas from a preceding stage or another gas source, is made up of several identical separators which alternate in carrying out the functional phases stated below in the sequence indicated so that there is at all times one separator carrying out functions within one phase. Phase 1 Gas is separated from liquid at a pres sure necessary to maintain export of gas from the process. Phase 2 Liquid is exported out of the separator by means of gas from a preceding separator stage or from another gas deposit. Phase 3 The separator is decompressed by gas be ing let out of the separator to a gas export line. |
