Small Refinery Exemptions from RFS Affect Ethanol Industry

Ethanol storage solutions are crucial as farmers and ethanol producers navigate challenges from changing regulations. The EPA recently denied 54 small refinery exemption petitions for “gap years,” a decision praised by ethanol and farm coalitions. However, challenges remain due to past lenient exemptions and the ongoing effects of COVID-19 travel restrictions, which reduced government penalties for small refineries facing deficits.

Storing Excess Ethanol from Decreased Demand

Farmers and ethanol refineries now hold surplus products that could lead to significant financial losses if not stored properly. Both ethanol and the grain used to produce it require careful storage to maintain quality and safety. Therefore, implementing proper ethanol storage solutions ensures product integrity and prevents spoilage.

Ethanol Storage Best Practices

Ethanol, being highly flammable, demands strict safety measures. Enclosed storage containers should maintain proper empty space above the liquid line to prevent gas buildup and potential hazards. Additionally, prolonged storage increases the risk of water absorption, leading to container corrosion and microbial contamination. These microbes produce acetic acid, which further degrades both the tank and the ethanol.

To avoid such issues, ethanol producers should use secure, sealed tanks, conduct routine water checks, and seek expert guidance for tank selection and maintenance. Moreover, reliable ethanol storage solutions ensure product integrity and prevent financial loss.

Dry Milled Corn Storage

Dry milled corn must be stored properly before undergoing the distillery process. Effective drying prevents moisture buildup, which can obstruct material flow and cause hazardous blockages like bridging, caking, or ratholing. In addition, proper temperature control plays a vital role in preserving grain quality. High temperatures create moisture, promoting microbial growth and mold activity.

By implementing effective airflow, consistent maintenance, and precise temperature control, farmers can significantly extend the shelf life of dried corn, ensuring it remains suitable for ethanol production.
