Abstract:
A method, comprising the steps of:driving a fluid into a process unit through utilization of a propulsion unit operating in a process mode; performing a process in the process unit utilizing the fluid; collecting contaminated fluid from the process unit in a collection unit; setting the propulsion unit to operate in a recycle mode through placing a first control valve and a second control valve to a recycle mode position by coupling a first port opening of the first control valve with an inlet of a pump, coupling a second port opening of the first control valve with an outlet of the collection unit, coupling a first port opening of the second control valve with an outlet of the pump, and coupling a second port opening of the second control valve with an inlet of a recycling unit; and driving fluid contaminated by the process into a recycling unit through utilization of the propulsion unit operating in the recycle mode.
