19/2/2019, · In the supercritical fluid (CO 2) extraction, CO 2 is liquefied under pressure and heated to the point that it has the properties of both a liquid and gas. This liquefied fluid then acts as the solvent in extracting the oil. After oil extraction from algae, the remaining biomass fraction can be used as a high protein feed for livestock. This gives further value to the process and reduces waste. Industrial reactors

Supercritical carbon dioxide (scCO 2) is the most commonly used solvent in supercritical fluid extraction. scCO 2 solvent has highly desirable properties such as non-toxicity, non-flammability, non-explosiveness, low cost, readily availability and ease of removal from the extracted materials [14]. Moreover, CO 2 has a low critical temperature (Tc = 31.1 °C)

“A single compressor for a 100-megawatt CSP system can run $7 to 20 million—so there’s a real opportunity for design innovation to support alternative energy by getting as much cost out as possible. This is where our core competency of ,oil,-free bearings was a great fit because ,oil, is reactive with s-,CO2,, and causes corrosion.
