Supercritical CO2 Extraction and Purification

Aqueous Gold (AG), located in Santa Barbara, California, is an early stage technology company building the only continuous supercritical CO2 extraction and purification equipment. Our patented equipment can reclaim valuable products, or extract the hazardous molecules from waste streams. It can deliver low cost ultra-pure separations for biofuels, nutraceuticals, flavors and fragrances, cosmetics, and foods. It can make low cost separations of edible oils and petrochemicals. It can pasteurize or sterilize fruit or vegetable juice, retaining all the original fresh squeezed nutrition and flavor.  We are developing a new capability for petroleum pre-purification of crude oil at the wellhead.  AG-Continuous technology costs much less than batch CO2, and replaces destructive conventional thermal methods, by purifying or extracting below body temperature, so no thermal damage can occur. We recycle CO2 for a carbon neutral footprint, and provide huge energy savings compared with all thermal methods.

Advantages of Aqueous Gold's AG-CONTINUOUS Supercritical CO2 Process

Nutraceuticals Fresh Juices Biofuels Botanicals Edible Oils
Supercritical CO2 (SCCO2) is the gold standard for non-degraded extractions of unsurpassed purity. Many products are potentially extractable by the old SCCO2 batch process. However, only premium priced products can justify the very costly batch method. The AG-Continuous process changes everything. Equipment costs less than batch; and our counter-current membrane-enhanced process is so efficient that any CO2-soluble product can be extracted profitably. It extracts either liquids or solids (fresh or dried), and can operate 24/7. Modified for purification, AG-Continuous will pasteurize feed liquids between 6-log to 7-log microorganism reduction (thats 10 to 100 times more pure than the FDA mandated 5-log reduction), or it will even sterilize. All purification can be performed at less than body temperature…  Find out more
