Artisan’s Dualflo^® Trays handle separations that require fractionation to obtain a pure overheads and bottoms stream.

Application: Purifying Glycols

Problem: Recovering ethylene or propylene glycol (used as antifreeze to disperse and remove ice forming on condensers or for deicing aircraft) that is contaminated with floating particles such as dust, salt, sand, etc.

Solution: Use Artisan Dualflo distillation trays.

For over forty years, companies have recovered high purity reusable glycol using these proprietary trays. The water vapor stream is glycol free (20 PPM or less) and safe for discharge to the atmosphere. Dualflo trays do not use down comers or overflow weirs and, therefore, stay clean and maintenaince free longer than conventional trays. more …

Artisan can also work with you to specify and design packed towers using low-pressure drop-structured packing.

For distillation processes that involve the purification of heat sensitive, viscous or solids-containing products, Artisan recommends using Rototherm E evaporator in place of conventional reboilers to improve both yield and purity. Rototherm offers the advantages of simplicity of operation with extremely short residence time and minimal holdup volume. For more information on the use of Rototherm as a reboiler please refer to our Rototherm E evaporator page.
