Supercritical Fluid Extraction+supercritical Fluid Chromatography

high pressures also requires special equipment. In summary, both RESS crystallization and SAS crystallization appear to be promising methods for generating supersaturation and therefore represent alternatives to conventional crystallization. Such alternatives may prove attractive in applications such as polymer and pharmaceutical processing, or in particle design for drug delivery. It is possib...

Lipid Extraction from Wheat Flour Using Supercritical Fluid Extraction

Cereal Chem. 81(6):693–698 Environmental concerns, the disposal cost of hazardous waste, and the time required for extraction in current methods encouraged us to develop an alternate method for analysis of wheat flour lipids. Supercritical fluid extraction (SFE) with carbon dioxide has provided that medium and the method is fully automatic. Crude fats or nonstarch free lipids (FL) were extracte...

Optimizing Supercritical Fluid Extraction Systems

Supercritical fluid extraction systems can be configured in a number of different ways and the operating conditions can span the full continuum of temperatures and pressures. Every combination presents differing solubilities and mass transfer behaviour and results in different cost. Optimal conditions for processing are rarely coincident with optimal conditions for maximum solubility. For a typ...
