EUROFILM has since its establishment in 2000, become a leading supplier of membrane based VOC separation solutions within the oil and petrochemical industry.


The EUROFILM patented manufacturing technology of flat-sheet thin-film composite membranes can be arranged in spiral-wound or plate-and–frame modules for VOC recovery.


VOCZero has joined its forces with EUROFILM, who has installed more than 500 VOC separation units, based on membrane technology. The combination of VOCZero’s cutting edge activating carbon technology and EUROFILM’s leading membrane separation position, results in an outstanding performance of VOC recovery, especially in the petrochemical industry, where extremely high emission requirements are prevalent.


The fundamentals of membrane permeation

The separation of VOCs through a membrane, is determined
on the gas permeation ratio. This depends on the individual
gas component’s solubility and diffusivity rates in the
membrane. The driving force of the VOC separation is the
difference between partial pressures of each individual VOC
component on both sides of the membrane.
The gas component with a high permeate ratio, diffuses
rapidly through the membrane and becomes a VOC-enriched
“permeate” stream, while gas components with a low permeate
ratio, are rejected passage through the membrane,
and flows on the surface of the membrane, leaving this in the
residue flow.


Spare membrane modules

If your existing membrane modules have lost their efficiency, are damaged, or in other ways degraded, we can supply you new replacement
modules. If you send us an inquiry, we shall give you a very favourable offer, and we are able to supply new modules with a very short delivery
