Whitefox’s ICE® uses membrane-based cartridge technology that enables clients to produce ethanol to the highest market standards in the most energy- and water-efficient way.

With a small footprint, Whitefox’s scalable systems can be adapted to a variety of processes and organic solvent applications such as ethanol, butanol or methanol. ICE can be integrated into existing production plants as well as new builds.

Over the past decade, Whitefox has built a diverse portfolio of projects, each uniquely tailored to match a range of customer requirements: capacity expansion, steam savings, high purity products, small footprint and ease of integration.


Molecular sieves are commonly used for ethanol dehydration. Recycle streams generated during distillation and molecular sieve dehydration create bottlenecks and limit plant expansion:

  • Molecular sieves regenerate streams are recycled to distillation increasing load and energy consumption in the columns
  • Fusel Oil Draws (FOD) from distillation columns have to be reprocessed in the molecular sieve, blended with the final product (adding moisture) or go through water intensive decantation


  • A proprietary, non-intrusive, bolt-on membrane solution
  • Whitefox ICE can dehydrate water-rich recycle streams (up to 50 wt%) to target moisture in one pass
  • Processing recycle streams increases capacity up to 25% by eliminating process bottlenecks
  • Efficient heat integration conserves gas energy leading to a reduction of Natural Gas consumption by up to 15%
  • Efficient engineering design reduces demand for cooling water, especially critical in summer months
  • Reducing carbon intensity by 1.5 points

The Benefits

  • Reduce steam consumption of DD&E to 1,500 BTU/gal
  • Stable, continuous operation of distillation and dehydration (no pressure swings)
  • Cooling water reduction
  • Diversify to lower moisture for export
  • Re-use existing infrastructure
  • Carbon emission reduction up to 1.5 CI points

  • Reduction in operational and maintenance cost

Whitefox provided that answer

What we were looking for recently was a capacity increase and we knew we had distillation maxed out so we had to find a way to increase our capacity in distillation without having to purchase an entire new distillation system and Whitefox provided that answer.
