摘要： An internal heat exchange-type distillation column integrally having a recovery section and a concentration section. Heat transmission means is provided on the surface of the concentration section adjoining the recovery section, and the means is received in the recovery section. Steam is directly supplied to the heat transmission means from the concentration section side, heat is transmitted from the means to the recovery section, and after the transmission, condensate liquid is returned to the concentration section. With the structure above, heat in the concentration section is efficiently used in the recovery section. At least one opening/closing section is provided, or the recovery section and the concentration section are separatably constructed, so that the content in the recovery section and the concentration section can be easily exchanged or cleaned, facilitating maintenance.

摘要： A method for continuously producing a fatty acid ester of the present invention comprises (a) mixing and agitating an oil and fat starting material and a lower alcohol, and supplying a mixture to one of the catalyst reaction tubes filled with a lipase; (b) producing a fatty acid ester and glycerin in the catalyst reaction tube; (c) introducing an outflowing liquid from the catalyst reaction tube into a glycerin separation tank, thereby collecting the glycerin; (d) adding a lower alcohol to a separated liquid obtained by separating the glycerin from the outflowing liquid, mixing and agitating an obtained material, and supplying a mixture to a following catalyst reaction tube; (e) repeating the steps (b) to (d) until supply to a last catalyst reaction tube is performed; and (f) collecting a fatty acid ester from the separated liquid obtained from the last catalyst reaction tube. According to the method of the present invention, the concentration of a lower alcohol can be strictly controlled and by-product glycerin can be automatically removed.
