Process: Ethanol Production

Location: Iowa

Background: To provides turnkey dry mill plant engineering and construction

Problem: As a result of the ethanol production processes, emissions from various sources require oxidation. In addition, a significant portion of the energy used in the emissions oxidation process is recovered to supply steam for plant operations.

Process Emissions: Ethanol production emissions include carbon monoxide (CO) and a variety of organic hydrocarbons.

Solution: Air Clear engineers designed, fabricated and installed a complete recuperative thermal oxidizer system which guarantees destruction of the CO and organics while producing steam for plant-wide production demand.

Process Equipment: The system is a direct-fired recuperative thermal oxidizer. It includes a custom-designed Low NOx burner, fuel delivery system, process gas injection system, recuperative heat exchanger and heat recovery steam generator (by others).

Special features allow the system to automatically modify oxidizer operations to continuously meet changing plant steam demand while maintaining destruction of plant emissions.

The entire system is remotely operated via a state-of-the-art distributive control system (DCS).
