Ceramic ultrafiltration membranes for non-solvent vegetable oil degumming (phospholipid removal)

Membrane reactors for biodiesel production and processing

“…Ultrafiltration, a pressure-driven membrane separation process, separates different molecules in a liquid mixture (Paris, Pierrette, & Francoise, 2002). This method is environmentally friendly and economical in comparison to conventional techniques (Koris & Edit, 2006;Yeh, Chen, & Chen, 2000). The experimental results of numerous investigations have proven that a two-phase system is required for a high membrane separation (Li-Hua, Ya-Fang, Shih-Yang, & Junghui, 2009); adding a low amount of water to the obtained mixture results in a better separation while methanol addition decreases the rate of separation by increasing the solubility of glycerol in FAME (Saleh et al, 2010).…”

State of art of the application of membrane technology to vegetable oils: A review

“…Recent research on the application of membrane technology to vegetable oils has mainly targeted desolventization (Koseoglu, Lawhon, & Lusas, 1990;Kwiatkowski & Cheryan, 2005;Ribeiro, Moura, Gonçalves, Petrus, & Viotto, 2006); deacidification (Kale, Katikaneni, & Cheryan, 1999;Manjula & Subramanian, 2006;Zwijnenberg, Krosse, Ebert, Peinemann, & Cuperus, 1999); degumming (García, Álvarez, Riera, Álvarez, & Coca, 2006;Kim, Kim, Lee, & Tak, 2002;Koris & Marki, 2006;Marenchino, Pagliero, & Mattea, 2006;Moura, Gonçalves, Petrus, & Viotto, 2005;Pagliero, Mattea, Ochoa, & Marchese, 2007;Subrahmanyam, Rao, Balasubrahmanyam, & Bhowmick, 2006); the synthesis and purification of structured lipids (Moura, Gonçalves, Sarmento, & Petrus, 2007;Moura, Ribeiro, Grimaldi, & Gonçalves, 2007;Xu, Balchen, Jonsson, & Adler-Nissen, 2000); the separation of compounds present in trace amounts in the oil such as antioxidants, and the removal of pigments.…”

Refining of Crude Canola Oil using PSA Ultrafiltration Membrane

“…Concerning the removal of FFA and PLS simultaneously, a few patents described dead-end microfiltration (MF) based refining of oils (Segers, and van der Sande, 1990). Ceramic ultrafiltration membranes are also used for non-solvent sunflower oil degumming (Koris and Marki, 2006). Recently, the development of hexane-resistant membranes have created opportunities for applying membrane technology to crude vegetable oil refining to simplify the whole process, reduce energy consumption and reduce wastewater production (Lin, et al, 1997).…”
