Application 01
Solvent dehydration and purification
Selective water removal from process solvents to specification, without entrainers or molecular sieves, for reuse in production.

Chemical & Petrochemical
plants and separation, end to end.
Chemical and petrochemical plants run on pressure equipment and on separations that decide product purity and energy cost. We fabricate the columns, reactors, vessels, and packaged units, ASME and API code-stamped, and we bring our own membrane IP for the separations distillation struggles with: solvent dehydration, azeotrope breaking, VOC and monomer recovery, and process-water reuse. Basic and specialty chemicals, solvents, polymers and resins, and refinery streams.
What you get
Outcomes our customers see.
Specific to chemical & petrochemical. Verified on real projects. The numbers below come from work we have shipped, not data sheets.
- Solvent dehydration purity
- 99.5 wt%
- Pervaporation dries ethanol, IPA, and acetonitrile past the azeotrope without an entrainer.
- Energy vs distillation
- 1/4 to 1/2
- No phase-change penalty on the separation step; membranes run near process temperature.
- VOC and monomer recovery
- >98%
- Vapor permeation recovers solvents and monomers from reactor and dryer offgas for reuse.
- Process debottlenecking
- A membrane stage ahead of a distillation train lifts capacity without a second column.

What we deliver.
The specific scopes and separation problems we solve for chemical & petrochemical operators.
Application 02
Azeotrope and close-boiling separations
AZEO-SEP® pervaporation separates compositions distillation cannot reach, ethanol/water, IPA/water, and other close-boiling mixtures.
Application 03
VOC, monomer, and hydrocarbon recovery
Recover valuable volatiles from vent and offgas streams, cutting emissions and returning product to the process.
Application 04
Process water reuse and concentration
AQUA-SEP® and MD recover process water from chemical effluents and concentrate the reject toward ZLD.
Application 05
Distillation debottlenecking
Hybrid membrane-plus-distillation trains lift throughput and cut reboiler duty on existing columns.
Fabrication scope
What we build for this sector.
Most chemical and petrochemical projects start with a fabrication scope: distillation columns, reactors, pressure vessels, and packaged units, built in our shops to ASME, API, and PED code. The membrane recovery system is engineered and built on the same floor, under the same project manager.
Vessels
Pressure vessels & tanks
Code-stamped pressure equipment, separators, columns, reactors, and storage tanks.

Membrane technologies
The right process for the fluid.
Chemical and petrochemical separations split between the liquid solvent side, handled by pervaporation, and the vapor side, handled by vapor permeation. We pair them with VMD on the aqueous streams and crystallization at the tail when the site needs zero liquid discharge.
PV
Pervaporation
Selective separation of liquid mixtures, including the azeotropes that distillation cannot break.

VP
Vapor Permeation
Vapor-phase separation for solvent dehydration and VOC recovery in chemical and pharmaceutical operations.
Learn more
VMD
Vacuum Membrane Distillation
High-recovery treatment for high-salinity and complex feeds where reverse osmosis cannot go.
Learn more
ZLD
Zero Liquid Discharge
Closed-loop systems that recover water and isolate solids for industrial wastewater.
