Pass-through Distillation Pilot Plant

In 2014 two Canadian Companies collaborated to test Pass-through distillation experimentally.

One of the companies,Fielding Chemical Technologies Inc., is Canada’s foremost chemical recycler. Fielding wanted to learn through the pilot plant whether or not PTD could offer advanced treatment of hazardous industrial waste.

The other company, Drystill Holdings Inc., is a start-up technology company that has invented and patented equipment specifically for PTD, including the Stripper/Absorber Module (SAM) described in the fifth and sixth lectures of PTD 101. The pilot plant featured a mid-sized SAM capable of boiling 50 Kg of water per hour.

The pilot plant operated successfully for many months before being dismantled to make way for another project. For Drystill it furnished proof of concept for their proprietary technology. Fielding learned that the technology may be applied to the processing of industrial wastes, but has decided not to implement it for the time being.

This is a picture of Drystill’s prototype SAM. It contains 100 heat pipes 25 mm in diameter and 550 mm in length.


Here is the same SAM installed on Fielding’s pilot plant framework.
