Abstract
A combined machine for pumping and separating into two distinct and purified phases a two-phase liquid/gas mixture or fluid, is provided. A first stage of the combined machine is equipped with an intake for the two-phase fluid, in which the two-phase fluid is sucked, pumped and partially separated into two distinct phases. One phase is mainly liquid and the other phase is mainly gaseous. A second stage of the combined machine includes two zones, which includes a first zone and a second zone. In the first zone, the mainly liquid phase extracted from the first stage is degassed. In the second zone, the mainly gaseous phase extracted from the first stage is dried. In a third stage of the combined machine, the degassed liquid is forced back and pressurized.
