EQUIPMENT AND METHOD FOR SOLVENT REMOVAL FOR FEED OF REST RESIDUAL PRODUCT AFTER BIODIESEL LIPID EXTRACTION OF MICROALGAE

摘要

PURPOSE: Preprocessing apparatus and method of removing chloroform/methanol for producing feed using biodiesel lipid extraction process byproducts are provided to effectively remove toxic organic solvents from the byproducts. CONSTITUTION: A producing method of removing chloroform/methanol for producing feed using biodiesel lipid extraction process byproducts comprises the following steps: extracting lipid from Chlorella sp. using the chloroform/methanol as a solvent; filtering the extract to obtain solid portion, and crushing the solid portion; adding distilled water into the crushed solid portion, and processing the mixture using ultrasonic waves in 30kHz for 20 minutes; passing the mixture through first and second separation spaces(2, 4) with air outlets using pipes(1, 3, 5) for removing the chloroform/methanol; and drying the obtained solid portion.
