An Emergency Gas Scrubber is designed to control catastrophic gas releases from 68 kg (150 lb.) to over 2,727 kg (6,000 lb.) while mitigating any risk to human lives in the surrounding communities. This scrubber prevents toxic chlorine (Cl2), sulfur dioxide (SO2), or ammonia (NH3) gas releases, resulting from a failure in the storage cylinder or system, by providing immediate removal of leaking gas. Nothing is more important than protecting the safety of the people living nearby.

Scrubbing is a common name given the unit operation normally known as gas absorption. In this process,mass is transferred from the gas phase into a liquid for the purposes of removing material from the gas stream. Obviously, the material to be transferred has to be soluble in the liquid for the process to be effective and herein lies one of the most important aspects of scrubbing: selection of the proper scrubbing liquid. In most air pollution control applications, the materials to be removed are usually acidic or basic gases even though in some cases, organic vapors are also present. Most of the inorganic contaminants are sulphur, phosphorous, halogen, or nitrogen oxides or acids. In other cases, ammonia or chlorine are of concern. Wet scrubbers can achieve extremely high contaminant removals and can operate at a variety of loads. Operation and control are simple, very stable, and ideal for remote, unattended locations. Scrubbing can achieve simultaneous removal of various contaminants as well as provide a measure of gas cooling and particle emission control. With the correct configuration, a scrubber can be used to remove acids and alkalies, or even soluble organic compounds. Scrubbing produces a liquid waste stream in many cases that has to be dealt with, but in the majority of the cases, this liquid stream does not require post-treatment beyond neutralization.
