Molecular Separation with Organic Solvent Nanofiltration: A Critical Review
Molecular separation via Organic Solvent Nanofiltration(OSN) is one of the most promising technologies now seeing applications in the cannabis/hemp processing space. At the most basic level the process can be imagined as an advanced high pressure filter cartridge which outputs two process streams, a retentate and permeate. The retentate is the fraction which for various reasons bypasses the filter membrane, while the permeate is the fraction which passed through. Many sophisticated variations and applications are possible which utilize various process layouts, solvent(s), solvent combinations and types of membranes.
OSN is a pressure driven process which operates at room temperature, allowing the removal of waxes and chlorophyll.
GPS now offers complete certified and peer reviewed skids utilizing OSN technology which allows a drastic reduction in costs for dewaxing operations over traditional temperature driven means of winterization.
