Effects of processing parameters on the caffeine extraction yield during decaffeination of black tea using pilot-scale supercritical carbon dioxide extraction technique

black nightshade oil extraction using supercritical fluid carbon dioxide

black nightshade is a weed plant that grows abundantly in most parts of iran. in this study, central composite response surface method to investigate the effect of temperature 35-55 °c and pressures 170-350 bar during the dynamic time of 120 min, the particle size of 150 microns and flow rate of 3 liters per minute on the efficiency of oil extracted from the fruits of black nightshade and optim...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Modeling of the Extraction Process of Tea Seed Oil with Supercritical Carbon Dioxide

The kinetics of the extraction of tea seed oil with supercritical CO2 was studied. A kinetic model of the extraction of tea seed oil using supercritical CO2 was developed on the basis of the differential mass balance to simulate the extraction process. The model could simulate the distribution of the solute concentration in CO2 inside the extraction bed as a function of extraction time and heig...
