Claim:
1. A system, comprising: a gas stream inlet for introducing a pressurized gas stream at an initial pressure level; a gas stream outlet; and a pressure reduction stage, comprising: wherein the pressure sensor places the control valve in an open position when the gas pressure within the knock-out bottle is at or below a first pressure level, and places the control valve in a closed position when the gas pressure within the knock-out bottle is at or above a second pressure level, wherein the pressure reduction stage, by way of batch processing gas flow, depressurizes the introduced pressurized gas stream to a lower pressure range comprising the first pressure level and the second pressure level; and a second pressure reduction stage, wherein the second pressure reduction stage is positioned between the output of the first pressure reduction stage and the gas stream outlet, wherein a gas stream exiting the outlet of the first pressure reduction stage is introduced into a knock-out bottle of the second pressure reduction stage through a control valve of the second pressure reduction stage; wherein a pressure sensor of the second pressure reduction stage places the control valve of the second pressure reduction stage in an open position when the gas pressure within a knock-out bottle of the second pressure reduction stage is at or below a third pressure level, and places the control valve in a closed position when the gas pressure within the knock-out bottle is at or above a fourth pressure level.
