HCl Scrubber Module

Global Technologies' 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 a Global Chloro-CatTM, is directed to the Global HCl Scrubber Module. A recirculation pump injects large volumes of water into a hastelloy eductor quench section; 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.

Global's Fully Integrated Approach
The Therm-Cat was designed as part of Global's entire line of soil and groundwater remediation products. The Global line of products, which includes Vapor Liquid Separators (Knockout Pots), Extraction Blower Packages, Oxidizers, and Acid Gas Scrubbers, is technologically advanced as well as user-friendly. Each module interfaces easily and is constructed for optimum performance and trouble-free operation.

When networked, the Global modules form a comprehensive subsurface remediation system that works continuously and automatically to achieve site closure quickly. In addition, Global's modular approach allows rapid deployment and provides the flexibility necessary to successfully perform site remediation under a wide variety of conditions.

System Components
Each Standard HCl Scrubber Module is fabricated from FRP and includes a hastelloy eductor, 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.
