Construction of a modular plant for the production of high-quality ethanol from corn-based fermentation feedstock is complete in Craig, Mo. The project has changed the skyline of the small town, according to Steve Lavorerio, president of the ChemPro Group LLC, Boonton, N.J., designer and builder of the modular plant.
Golden Triangle Energy contracted with ChemPro for an expansion of its existing ethanol production plant in Craig. ChemPro is a full-service design-build company specializing in modular process solutions, prefabricated assemblies and project management. According to Lavorerio, ethanol-process-technology company Katzen recommended ChemPro because of the company's depth of understanding of the bio-ethanol process and extensive expertise in separations and modular system design and fabrication. Its expertise in mass transfer and separations technology such as distillation and liquid-liquid extraction gave ChemPro an edge in gaining the contract.
The modular design consists of seven process modules, a stair tower module to connect and provide access to the other modules, and four freestanding distillation and dehydration columns. The plant was built and assembled at ChemPro's fabrication partner, McAbee Construction of Tuscaloosa, Ala., and transported to Craig, Mo., by truck. The plant started up in July and is now producing ethanol of a quality that exceeds the design parameters for the plant.
