| Supercritical fluid technology is especially useful for manufacturing products of standardized concentration of active ingredients, and products of much higher concentration (higher yields and purity) and quality (with less creation of artifacts), than possible by conventional chemical engineering unit operations, such as liquid/liquid extraction, distillation, mechanical micronization, liquid and/or gas phase reactions. Supercritical extraction technology is especially attractive for extraction of natural ingredients when extraction and fractionation can be accomplished simultaneously in the high pressure process. This can be accomplished effectively utilizing supercritical carbon dioxide when optimized process operating and separation conditions are selected. Also, the design of the high pressure equipment needs to be customized to promote high levels of extraction and fractionation efficiency. This poster illustrates the selection of operating conditions to maximize both yield and selectivity utilizing several examples. Also, the design of the high pressure processing equipment for maximum extraction and fractionation efficiency will be discussed. |
