The biomass that will be used would be clean wood scraps from furniture manufacturing and forestry cuttings. The gasifier would create a renewable fuel for the thermal oxidizer (TO) which is required to destroy at least 95 percent of the Volatile Organic Compounds (VOC) generated during ethanol production. Waste heat generated from VOC destruction will be used to create steam for electric power generation, process steam, and hot air for the plant’s dryer.
This project includes a single gasifier with a design throughput of approximately twelve tons of clean scrap wood per hour.
Ash from the gasification process would be either
disposed of in an approved landfill or would be land-applied as a fertilizer. The MPCA approval would have to be granted for any land application
process.
An annual limit of 6.2 million gallons of propane burned per year in EU021, EU028 and
EU029 has been added to the permit. Record-keeping requirements for propane usage have
also been added.
• The limit on the amount of distillate oil burned in the boilers has been reduced from
2,500,000 gal/yr to 667,000 gal/yr
For SV008, the total particulate matter and PM10 emission limits have been raised from 6.9 to
9.0 lb/hr. The VOC limit for SV008 has also been raised from 4.8 to 10.0 lb/hr.
