Abstract
A system for separating a gaseous constituent from a gaseous mixture includes an ionization chamber, suction plenums separated from the chamber by an anode or a cathode, suction pumps for drawing gas from the plenums, and a throttle valve for controlling the entry of gas into the ionization chamber so as to maintain the chamber at a pressure less than atmospheric. The ionization chamber is bounded by an anode and a cathode, which are separated by a volume for containing the gaseous mixture. When the electrodes are oppositely charged, ions of a gaseous constituent are drawn towards the electrode of opposite polarity to the ions, and away from the other electrode. As ions approach the electrodes, they are collected and sucked though exhaust ports by the pumps.

A system for separating a gaseous constituent from a gaseous mixture, comprising:
- an ionization chamber having an entry port for discharging the gaseous mixture into a substantially enclosed volume, the volume disposed between an anode and a cathode;
- first suction means disposed against the anode, for suctioning the gaseous mixture from the substantially enclosed volume through the anode, the first suction means configured to pump at a first suction rate;
- second suction means disposed against the cathode, for suctioning the gaseous mixture from the substantially enclosed volume through the cathode, the second suction means configured to pump at a second suction rate;
- and
- an adjustable throttle valve located upstream and in series with the entry port and configured to control flow into the ionization chamber at an inlet rate not greater than a sum of the first suction rate and the second suction rate, whereby the ionization chamber is maintained at a static pressure substantially less than atmospheric when the first suction means and the second suction means are operating.
A system for separating a gaseous constituent from a gaseous mixture, comprising:
- an ionization chamber having an entry port for discharging the gaseous mixture at a rate controlled by an adjustable throttle valve into a substantially enclosed volume, the volume disposed between an anode and a cathode, said throttle valve located upstream and in series with respect to the entry port;
- a first suction plenum separated from the enclosed volume by the cathode, in fluid communication with the enclosed volume and evacuated by a first vacuum pump;
- and
- a second suction plenum separated from the enclosed volume by the anode and evacuated by a second vacuum pump, in fluid communication with the enclosed volume, whereby pressure within the ionization chamber is maintained at a low vacuum pressure when the first vacuum pump and the second vacuum pump are operating.
