A method in which a fluid is driven into a process unit through utilization
of a propulsion unit operating in a process mode. A process is performed
which utilizes the fluid in the process unit. The propulsion unit is set
to operate in a recycle mode and fluid contaminated by the process is
driven into a recycling unit through utilization of the propulsion unit. A
system comprises a process unit that utilizes a liquid to perform a
process. A recycling unit recycles fluid contaminated by the process. A
propulsion unit coupled to the process unit and the recycling unit is
adjustable between a process mode and a recycle mode.
