OEM Equipment and Engineered Systems
Dry Sorbent Injection Systems
IAC offers innovative dry sorbent injection and semi-dry sorbent injection technology, engineering, and construction services for gas stream conditioning systems that remove VOCs and Hazardous Air Pollutants (HAP) such as SO2, SO3, NOx, Hg, HCL, Dioxin, and PM2.5 from process gas streams. Our solutions have proven successful in assisting industrial and mining companies meet National Emission Standards for Hazardous Air Pollutants (NESHAP), Mercury and Air Toxics Standards (MATS), New Source Performance Standards (NSPS), and Maximum Achievable Control Technology (MACT) standards compliance.
Dry Sorbent Injection (DSI) Systems for Flue Gas Desulphurization (FGD)
IAC designs and installs dry sorbent injection (DSI) systems, which are a type of dry scrubber, for flue gas desulphurization. We offer both engineering design and installation of new or replacement permanent sorbent gas stream conditioning systems, and temporary test rigs for analysis of current sorbent system effectiveness.

Dry Sorbent Injection for SO2 Control: Perminant Solutions
IAC offers permanent solutions to reduce SOx, SO2 and SO3, and HCI from boiler flue gasses with our permanent dry sorbent injection (DSI) equipment and systems.
We assist customers select proper injection points and choosing correct dry sorbent medium for maximum acid gas control efficiency. IAC provides equipment, installation, and employee training as a complete turnkey solution for your DSI requirements.
During this process, IAC’s DSI Systems inject dry sorbent into the flue gas after the boiler to reduce concentrations of acid gasses (SO2, HCI and HF). These are highly regulated gases that are linked to acid rain. With IAC’s Two-Step Process, the powdered sorbent is injected into the flue gas and the compound is removed downstream by the existing precipitator or baghouse.

Dry Sorbent Injection (DSI) - Temporary Test Rigs
Dry Sorbent Injection for SO2 Control: Temporary Rigs for Testing and Analysis
IAC offers customers cost effective, rentable mobile testing rigs backed up with expert field service support. This turnkey package provides customers our self-contained FGD Test Rig, trained technicians, data acquisition, and documentation equipment for continuous 24-hr. Acid Gas Mitigation Flue Gas analysis. After testing and analysis, IAC can recommend SO3 Mitigation strategies and equipment. Testing of multiple sorbents can provide multi-pollutant Acid Gas Mitigation for SO3, Hg, HCL, Dioxin, and others.

Semi-Dry Flue Gas Desulphurization (FGD) – Dual Fluid Nozzle injection
IAC provides Semi-Dry FGD (SDA) Dual Fluid Nozzles Injection systems for Flue Gas – Acid Gas Mitigation. Complete testing, demonstration services, and equipment can be provided by IAC`s trained technicians utilizing our own self-contained Flue Gas Desulphurization Test Rig.
Selective Non-Catalytic Reduction (SNCR) for cement production
A properly designed and operated SNCR system can result in 90-95% reduction of NOx. Through the process of injecting Ammonia into the flue gas stream, the NOx levels are reduced significantly at a lower cost than other flue gas exhaust treatment systems.
Cement producers should download our SCNR Systems for Cement Applications (PDF) product sheet for quick reference information, or our full Engineered SNCR Systems for Cement Applications (PDF) presentation for a detailed explanation of our SNCR methodology.
