Distillation is an ubiquitous industrial activity. Although largely hidden from the public eye, it accounts for one tenth of all the energy used on earth for any purpose. Pass-through distillation may help to varying degrees the industries listed below:

Beverages & liquor
Food & health food
Oil & gas
Pulp & paper
Speciality chemicals
Waste processing
Waste-water recycling

In some industries the benefits of PTD go no farther than energy reduction. In other industries low temperature operation leads to higher product quality. In yet others PTD is an enabler for revolutionary process changes. This is the case for the biofuel/ biochemical industry described on its own page.
