Case Study: a fuel ethanol plant achieves continuous sulfate compliance with Kurita America’s Ethanol Final Filter

a fuel ethanol plant treats 100 million gallons with Kurita America's Ethanol Final Filter

A fuel ethanol plant encountered a significant final product sulfate issue after implementing process changes. This problem prevented them from meeting quality specifications, and while blending offered some relief, it created logistical challenges. The plant looked to Kurita America for a solution and chose to implement their Ethanol Final Filter (EFF) system.

Kurita America deployed their proprietary EFF system, a mechanical/chemical solution that treats ethanol en-route to storage. The system successfully resolved the sulfate issue, consistently meeting the 4 ppm sulfate standard even during inlet excursions. At this single location, the Kurita America system treated over 100 million gallons of ethanol in 22 months with continuous, uninterrupted operation.
