Anguil's HCl Scrubber Module scrubs and neutralizes hydrochloric acid that is created during the oxidation of halogenated or mixed organic vapor contaminants.

How the HCl Scrubber Module Works

The outlet of a catalytic oxidizer, such as an Anguil Chlorinated Catalytic Oxidizer, is directed to the Anguil HCl Scrubber Module. A recirculation pump injects large volumes of water into a hastelloy quench section, inducing vapor flow through the scrubber. The water quenches the hot vapor and absorbs a portion of the HCl. The gases exit the eductor and enter a countercurrent absorption column. Recirculating solution is fed to the top of the absorption column through a nozzle. The remaining hydrochloric acid vapors are absorbed into the solution. The gases pass through a mist eliminator before exiting the column. Sodium hydroxide is added to control pH in the neutral range.

Anguil's Cost Effective Design

The HCl Scrubber Module is designed as part of Anguil's broad line of technologically advanced, yet user-friendly, air pollution control products. The Anguil product line includes over 1,600 installations of Recuperative and Regenerative Catalytic and Thermal Oxidizers ranging in size from 100 to 100,000 SCFM (150 to 150,000 NM3/hr), Ceramic Filter Systems, Soil Remediation Equipment, Rotor Concentrators and Scrubbers. Each product line represents value-engineered systems with emphasis on cost minimization. All systems are designed for optimum performance and trouble-free operation.

Anguil strives to provide innovative pollution control technology including process analysis, engineering, equipment manufacturing, installation and post-sale 24-hour service.

System Components

Each Standard HCl Scrubber Module is fabricated from FRP and includes hastelloy quench, absorption column (consisting of a cylindrical tower filled with polypropylene spherical media), common liquid sump, recirculation pump, flanged inlet and outlet, hastelloy spray nozzle and liquid level indicator. The system components are assembled on an epoxy-painted steel base that is weather-resistant and corrosion-resistant.
