If you're storing chemicals that emit fumes such as hydrochloric acid or hydrogen peroxide, you need to have a proper venting system in place. We've developed The PolyScrub™ fume scrubber to help you ensure the safety of your employees, equipment, and the environment.

Today we will be discussing the Poly Processing Company fume scrubber systems to help bring some clarity as to when and how to use it. It can be found on Page 13 of the Poly Processing Chemical Storage Tank System and Accessories Product and Resource Guide.
In all cases, chemicals stored in polyethylene tanks require venting. In some instances, the harmful fumes emitted from the chemicals cannot be directly released to the atmosphere. In order to reduce the harmful fumes before they evacuate the system and to control air pollution, fume scrubbers are installed.
Poly Processing Company offers a polyethylene chemical storage tank scrubber solution called PolyScrub. The PolyScrub™ is an ideal solution for customers in search of a cost-effective fume scrubber. The PolyScrub™ is engineered to address discharging vapor from chemical tanks during operation and filling. Each PolyScrub™ is designed by our application engineers to accommodate proper ACFM (Actual Cubic Feet Per Minute) for a given system.
Let's take a look at how the PolyScrub™ fume scrubber is built. We start with a crosslinked polyethylene open top tank. We then manufacture an Ultra High Molecular Weight lid with the necessary size fitting package for your specific application.
Once the lid is constructed we build a plenum also known as a diffuser which goes inside the tank. This plenum is used to distribute the fumes from the bulk tank into the liquid media of the wet scrubber.
The PolyScrub™ functions by contacting the target compounds with a scrubbing solution. Often, the solution is simply water, but can be a reagent to address specific chemicals.
Some of the chemicals that are stored in Poly Processing Company tanks which require scrubbers are hydrochloric acid, ammonia, and acetic acid.
When storing these types of chemicals, it's important to construct a system that addresses venting needs by installing a compatible scrubber.
As with typical wet scrubbers, the PolyScrub™ system introduces water or a specific scrubbing solution through a submerged plenum. The fumes percolate up and through the scrubbing solution, then vent out of the top of the scrubber system.
When fitting a PolyScrub™ system, normally a 6" vent pipe is installed in the bulk tank. The pipe elbows over and down and connects to a flange attached to the top of the scrubber. This allows the bulk storage tank to vent into the scrubber and not into the atmosphere.
Scrubbers are typically sized for the bulk storage tank being used and the chemical needing to be scrubbed. PolyScrub is available in two designs; a passive model which the operator checks and adjust PH or an actively monitored system.
Our actively monitored system automates PH control to ensure maximum performance
