In addition to the handling and disposal issues associated in these operations, these solvents can pose a number of environmental concerns such as atmospheric and land toxicity. In many cases, conventional organic solvents are regulated as volatile organic compound because of their contribution to the green house effect. In addition, certain organic solvents are under restriction due to their ozone-depletion potential. Supercritical carbon dioxide is an attractive alternative solvent in place of traditional organic solvents. Early applications of supercritical fluid include chromatography applications and extraction applications particularly caffeine extraction from tea and coffee. There have been an increasing number of commercialized and potential applications for supercritical fluids in reactions, catalysis, extraction involving natural products and pharmaceutical, polymer production and processing, environmental and soil remediation, cleaning processes, semiconductor processing, and powder production. This report reviews the fundamental of supercritical CO2 processing, current and potential applications, and patents. The technological and economical challenges involved in implementation of the technology in different applications are discussed. We also include process economic evaluation analyses of several supercritical CO2 applications: (1) Hydroformylation of octene, (2) Extraction using supercritical CO2, (3) Fluoropolymer production with supercritical CO2 as a polymerization medium, and (4) Polycarbonate production with supercritical CO2 as a raw material. © SRI Consulting PEP Report 269

CO2 GTL Gas to Liquids Experimental Platform: Experiment with gas to liquids (CO2 to alcohol) using Nafion (electrolyzer membrane) and our phase change demonstrator cart (we can ship worldwide). CO2 goes supercritical at 31 C. This is a experimental platform which you can use to demonstrate phase change with low heat. Includes integration area for small CO2 turbine, static generator, Nafion pellets, Nafion membrate, or Nafion tubes... More Info
Concept: The concept of the SeaMerlin Engine is to convert or supplement existing marine vessel propulsion to a gas leverage turbine which scavenges CO2 from saltwater at the same time it provides vessel thrust.
