Pittsburgh Specialty Gas Equipment Spotlight: Gas Purifiers


Here at Butler Gas Products , PurityPlus® specialty gases for commercial, industrial, medical, scientific, and agricultural use are the focus of our business. But customers have no doubt they also can count on us for everything needed to transport, stock, monitor, and use those gases safely. One such kind of equipment they appreciate is our line of gas purifiers.

The Pittsburgh semiconductor industry particularly looks to us for point-of-use gas purifiers that pull out impurities down to part-per-trillion (pptV) levels. This sort of purity is critical for manufacturing not only semiconductors but also all manner of display, LED, and solar products.

To be specific, we supply …

  • high-pressure gas purifiers, these models built for use in all types of laboratory and industrial applications where oil or water need to be kept out of a gas in order to improve its effectiveness and reduce the possibility of equipment shutdown.
  • gas purifiers that, while much like our high-pressure models, are engineered to deal with higher capacities at a reduced working pressure.
Each of these purifiers must used along with specially constructed replaceable cartridges containing one of a number of adsorbents. Depending on the cartridge/adsorbent needed, these purifiers can remove more than just oil and water from industrial process gases; they can also remove water from inert gases and saturated hydrocarbons, remove a variety of particulates, and remove water from unsaturated hydrocarbons – acetylene, for example.
  • a series of gas purifiers specifically made to remove up to 1% of oxygen from a hydrogen stream down to a level below 1 ppm. They do this by catalytic action. Provided the catalytic materials aren’t tainted (especially by sulfur and halogens), they’ll perform pretty much forever and not need regeneration.
