Iowa ethanol plant installs Whitefox ICE membrane solution

A Whitefox ICE membrane dehydration system is currently being installed at The Andersons Inc’s ethanol plant in Denison, Iowa, USA.

This is Whitefox’s 11th installation in the US and its fourth installation in Iowa. The installation project is in its last stages of completion and is due to be commissioned in October 2022.

“We have been evaluating Whitefox technology for some time, and saw that the system aligned with our goals for upgrading the Denison plant which include lower steam use and energy cost per gallon,” said Bill Krueger, president of The Andersons Trade and Processing. “It also helps to drive our objective of reducing carbon intensity across our production facilities. I am excited that this project is now nearing completion as it addresses several of our strategic priorities.”

The Whitefox ICE system treats existing recycle streams to free up and debottleneck distillation-dehydration capacity, enabling The Andersons to lower natural gas use, cut carbon emissions, improve plant cooling, and increase potential production capacity depending on the system design.

“The goal of this installation is to increase plant capacity while reducing steam consumption per gallon of ethanol produced,” explained Malcolm Rock, Whitefox Technologies COO. “Our process engineers designed a tailored solution that fits the distinctive features of the Dension plant emphasising on de-bottlenecking the plant, integrating heat where possible and to avoid significant capital cost in future expansions. Together with The Andersons, I am pleased to see the final stages of the project coming together and look forward to start-up and commissioning in October this year.”
