Background

Background To provide turnkey dry mill plant engineering and construction

Problem

PROBLEM As a result of the ethanol manufacturing process, 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 from the ethanol production process while producing steam for plant-wide production demand.

Process Equipment

The system is a recuperative and direct-fired thermal oxidizer (THERMOX™). 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).
