Oil extraction rates of soya bean using isopropyl alcohol as solvent

Recovery of Bio-Oil from Industrial Food Waste by Liquefied Dimethyl Ether for Biodiesel Production

“…Previous work has also found low amounts of oil remaining in the soybean and rapeseed cakes, after using both mechanical and organic solvent extraction methods [29,30]. Hexane is most often used as the extraction solvent in current industrial food oil extraction procedures [18], whereas the present results indicate that liquefied DME is more powerful than hexane for the extraction of oil from oil plants. In fact, the utilization of liquefied DME as a green solvent in the food industry has been approved by the European Food Safety Authority [13].…”

“…The annual global production of these IFWs is shown in Table 1. As representative edible oil waste products, the global production of soybean and rapeseed cakes is extremely high [18]. Furthermore, approximately 6 million tons of spent coffee grounds are produced annually at beverage factories [19].…”

Kinetics and thermodynamics of cottonseed oil extraction

“…The control of its emission levels in extraction plants requires the installation of additional control equipment at additional costs (Conkerton, et al, 1995). Seth (2007) has reported that the use of n-hexane in small capacity plants makes the process expensive because of high operating losses (typically ranging from 0.75 to 7.5 L/mT of processed seeds). further, n-hexane, being a petroleum product, faces occasional scarcity and fluctuation in price depending on the supply and demand of gasoline.…”

Soybeans Processing for Biodiesel Production

“…Hexane is extensively used for oil extraction from soybeans and other oilseeds because of its low vaporization temperature, high stability, low corrosiveness and low greasy residual effects (Seth et al, 2007). Johnson and Lucas (1983) proposed to use other non-petroleum www.intechopen.com materials instead of hexane as a solvent.…”
