See full text

A system and method for reducing the pressure of a pressurized gas is provided, the system including a pressure reduction stage, the pressure reduction stage including: a knock-out bottle; a control valve connected to a gas stream inlet and configured to introduce a gas stream at an initial pressure level into the knock-out bottle; an output connected to a gas stream outlet; and a pressure sensor for monitoring the pressure within the knock-out bottle and changing the operational state of the control valve to maintain the pressure inside the knock-out bottle within a pressure range. More than one pressure reduction stage may be implemented in series to provide a more gradual step down in the gas pressure.
