One of the most common processes in the chemical industry involves molecular separations: for example, purifying water for drinking, separating carbon dioxide from hydrogen, removing water from ethanol for alcoholic beverages or biofuels.
Conventional technologies separate molecules by applying heat (e.g. distillation), adding chemicals (e.g. extractive distillation) or by adsorption of one molecule over another (e.g. ceramic pressure swing). All such processes are energy and water intensive.
At Whitefox Technologies, we take our inspiration from natural separation processes. Our membranes separate molecules using the principle of solution/diffusion across a semi-permeable layer, a process that is commonplace in nature and does not consume energy. As a result, our solutions are able to provide substantial savings to our customers while improving the overall environmental footprint of industrial processes.
In addition, the membrane process does not require a regeneration loop, which reduces energy and costs further, nor does it require any added chemical.
Membrane characteristics that enable improved dehydration solutions:
- Water tolerance: up to 20% water in the feed.
- Operating pressure range: up to 6 bar A
- Operating temperature range: up to 160 °C (320 °F)
- Resistance to fusel oils
