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 (PV)?
A membrane process that separates liquids by affinity, not volatility: it dries solvents past azeotropes and strips organics from water.

What is vapor permeation (VP)?
A membrane process that separates saturated vapor feeds using a partial pressure difference.

What is membrane distillation (MD)?
A thermally driven process that uses a hydrophobic membrane and a temperature gradient to produce high-purity water.

What is zero liquid discharge (ZLD)?
A way of running a plant so that no liquid waste leaves the site: the water is recovered for reuse, and the dissolved salts leave as solids.

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.
