Acid Gas Removal
APC Technologies provides acid gas removal systems engineered to achieve 99%+ removal of HCl, SO2, H2S, HF, and other corrosive emissions.
By selecting the best-fit technology, from wet scrubbers to dry sorbent injection systems to activated carbon adsorption systems, we ensure total air permit compliance.
Acid Gas Removal Needs Served

APC’s Acid Gas Removal Systems
- Utilizes sorbent injection (e.g., hydrated lime, trona, sodium bicarbonate) together with a downstream baghouse (existing or new) to remove multiple acid gases in one system
- Ideal for when particulate is co-present with acid gases and also must be removed
- Other sorbents can be injected through the same equipment for simultaneous removal of mercury and/or VOCs
- All dry system — no wastewater to deal with
- System equipment supply can include sorbent injection system, baghouse, system fan, interconnecting ductwork, instrumentation, and controls
- Where enhanced performance is required, APC can provide additional technologies
Learn more about Sorbent Injection Systems
- Provide the highest removal efficiencies for many acid gas removal applications, including common contaminants such as HCl and HF
- APC’s designs maximize scrubber performance and cost efficiency through the use of up-front modeling and high-efficiency, low-loss packing
- GP scrubbers offer corrosion- and temperature-resistant construction as needed
Learn more about GP Series Wet Scrubbers
- For H2S, Cl2, and other acid gases
- Utilize single or multi-bed systems with tailored media to remove the contaminant(s)
- Dry process — no wastewater
- Generally lowest maintenance and simpler than other technologies
- APC is media-independent and will select the most cost-effective media that meets performance requirements

Choosing Acid Gas Removal Technologies
When evaluating acid gas control technologies, a variety of factors should be considered, including:
– Contaminants present
– Contaminant loading levels
– Gas conditions
– Required removal efficiencies for contaminant(s)
– Lifecycle cost of each technology
APC has no bias toward any technology and is pleased to present multiple technologies with a comparison of capital and operating costs.
