Emergency Vent Lab Scrubber

Posted by Andy Bartocci on Tue, Apr 19, 2016 @ 10:28 AM

Lab_Scrubber.jpgA common application for small scrubber systems is an emergency vent scrubber for laboratories. Envitech's lab scrubber is a packaged packed bed absorber designed for high efficiency removal of water soluble contaminants (e.g. HCl, HF, HBr, SO2, NO2, etc.) from the gas stream and can handle up to 500 acfm of gas at a maximum temperature of 180oF.  The system is engineered for reduced footprint at 4 ft x 4 ft and includes a pre-wired control panel and pre-piped service utility connections requiring minimal installation and maintenance costs. Scrubber units are configurable to different levels of automation and treatment applications.  A typical application might be a facility with a gas cylinder filling stations laboratory hood vent.  The scrubber comes with a fan, pump, instrumentation, and control panel and is shop fabricated and assembled.

New Ethanol Scrubber Reduces Plant Capital & Operating Costs

Posted by Andy Bartocci on Mon, Jun 22, 2009 @ 11:00 AM

I'm making plans to head to Denver for the upcoming 2009 International Fuel Ethanol Workshop and Expo, June 15-18 in Denver, CO.  Envitech has a booth at #1241.  I'll be giving a talk on our new, patent-pending ethanol scrubber which reduces capital and operating costs. 

The new Envitech ethanol scrubber reduces total organic carbon compounds (TOC) in the exhaust gases to acceptable levels without requiring thermal oxidation or chemical transformation.  The scrubber uses ethanol as a light alcohol solvent for the other, non-ethanol organic carbon compounds.  While these compounds have low solubility in water, they have high solubility in ethanol.  Because ethanol is readily available from the plant, it is an ideal solvent for these difficult to remove compounds. 

My talk is at:
