Engineering decisions, on the record.
Technical writing on the choices that shape real industrial separation systems. Membrane selection, fluid characterization, code-stamped fabrication, pilot validation. New articles publish on a monthly cadence.
What is pervaporation?
Pervaporation combines permeation and evaporation to pull a low-concentration component out of a liquid mixture, so it can dehydrate solvents past the azeotrope and recover VOCs where distillation cannot.

What is vapor permeation?
Vapor permeation separates a saturated vapor feed through a selective membrane driven by a partial-pressure difference. How it works, how it differs from pervaporation, and where it fits.

What is membrane distillation?
Membrane distillation is a thermally driven process that uses a hydrophobic membrane and a temperature gradient to produce high-purity water from difficult, high-salinity streams.

What is Zero Liquid Discharge?
Zero Liquid Discharge recovers clean water or solvent from a waste stream and turns the rest into dry solids, so no liquid effluent leaves the plant. How ZLD works and where it applies.

Cellulosic ethanol at pilot scale, where membranes earn their place
Pervaporation and vapor permeation cut the dehydration energy of cellulosic ethanol by roughly half versus conventional azeotropic distillation, with no entrainer column. A look at the technology stack, the Fiberight pilot, and how AZEO-SEP® and VOC-SEP® fit into a real train.
