Microalgal lipid is attractive feedstock candidates for biofuels and high value products. However, its manufacturing method, including lipid extraction, still needs to be developed for commercialization. To solve this problem, Hexane-based solvent extraction with cell disruption method is chosen and minimum amount of solvent is used. As a result, highly concentrated emulsion mixture of lipid-in-hexane, aqueous medium is made and usually centrifugation is used to separate solvent phase. But, centrifugation is slow batch process and expensive to operate. Therefore, new separation system using a hydrophobic/oleophilic surface-modified sponge is devised via initiated chemical vapor deposition (iCVD) process. The solvent phase is exclusively absorbed by simply dipping the modified sponge into mixture and extracted continuously by pumping out. This system shows high separation yield of 95% and flux of 2640Lm-2h-1 and can be applied to diverse separation process. |
