US Patent 12025054 Pump mixer separator unit

A pump mixer separator unit is provided in communication with a stripping gas line that provides an inlet stripping gas flow and a fuel line that provides an inlet fuel flow. The pump mixer separator unit includes a first pump in fluid communication with the stripping gas line and the fuel line to form a fuel/gas mixture flow and generate a first pressure rise from the inlet fuel flow to the fuel/gas mixture flow; and a second pump in fluid communication with the first pump, wherein the second pump receives the fuel/gas mixture flow from the first pump, wherein the second pump separates the fuel/gas mixture flow into an outlet stripping gas flow and an outlet fuel flow and generates a second pressure rise from the fuel/gas mixture flow to the outlet fuel flow, wherein the first pump includes a supplemental pump feature for drawing an inlet fuel flow through the fuel line during operation.
