Abstract:
In the method of processing a multi-component fluid mixture, and wherein a multistage two-phase turbine is provided to have one or more stages to receive fluid, each stage having an inlet and outlet, the steps includinga) providing nozzles at the inlet to each stage to accelerate said fluid that consists of a mixture of gas and liquid, to form two-phase jets,b) providing a rotating separator structure in the sub-surface well to receive and separate the two-phase jets into gas streams and liquid streams in each stage,c) the turbine provided to have a rotating output shaft, and there being means provided to convert the kinetic energy of the liquid streams into shaft power,d) providing means to remove the separated liquid from at least one stage and transfer it to nozzles at the next stage,e) providing means to remove separated liquid from the last stage and transfer it to primary outlet structure, andf) providing means to remove the separated gas from at least one stage and transfer it to a secondary outlet structure.
