Method for separation of electrolytes, and method for ion exchange of electrolytes with counter-ions
Patent number: 5015386Abstract: A method for separating electrolytes which have different charges of the same sign or of carrying out ion exchange of electrolytes with counterions, which comprises causing the electrolytes (anion or cation) to pass through a positively or negatively charged loose reverse-osmotic membrane, in an aqueous solution.Type: GrantFiled: July 18, 1988Date of Patent: May 14, 1991Assignee: Ajinomoto Co., Inc.Inventors: Toshiya Tanabe, Shigemitsu Abe, Masazumi Date, Tetsuya Kawakita -
Patent number: 4714767Abstract: A process for separating basic amino acids from a liquid containing the same using cation exchange resin towers in series, which comprises effecting repetitive adsorption and elution steps in sequence, wherein the washing water employed in said adsorption and elution steps is obtained by recycling the latter portion of a liquid discharged from a first tower of the adsorption step into an adsorption step in a subsequent cycle, or by recycling a liquid discharged from a first tower at the elution step into an elution step in a subsequent cycle.Type: GrantFiled: July 11, 1985Date of Patent: December 22, 1987Assignee: Ajinomoto Co., Inc.Inventors: Kiyoshi Tanaka, Masaru Saeki, Tsutomu Matsuishi, Yoshihiro Koga, Tetsuya Kawakita

Patent number: 4711722Abstract: A method for preventing fouling of an electrodialysis membrane when conducting desalting of an inorganic salt-containing aqueous solution containing electrodialysis membrane-fouling substances, which is characterized by adjusting the pH of the solution to the isoelectric points of the fouling substances.Type: GrantFiled: January 27, 1986Date of Patent: December 8, 1987Assignee: Ajinomoto Co., Inc.Inventors: Seiji Toyoshi, Tomoya Yoshizumi, Masaru Saeki, Tetsuya Kawakita
-
Patent number: 4663048Abstract: A method for separating a basic amino acid from its fermentation broth, or the liquid resulting from the intermediate treatment of the fermentation broth, containing high-molecular weight contaminants which entails permeating the broth, or liquids resulting from the intermediate treatment of the broth, through a semi-permeable membrane, until the basic amino acid is separated from the high-molecular weight contaminants, by passing through the membrane in the permeate; contacting the permeate with a strongly acidic cation exchange resin; and eluting the adsorbed basic amino acid from the cation exchange resin.Type: GrantFiled: March 20, 1985Date of Patent: May 5, 1987Assignee: Ajinomoto Co., Inc.Inventors: Kiyoshi Tanaka, Yoshihiro Koga, Masaru Saeki, Tetsuya Kaneko, Tetsuya Kawakita

Patent number: 4601829Abstract: A process for purifying lysine in a lysine production process, which involves passing a solution containing lysine over a cation exchange resin such that lysine adsorbs onto the resin, eluting adsorbed lysine from the resin with an aqueous solution of ammonia to produce a lysine-containing elution liquid, passing the elution liquid directly to a reverse osmosis membrane system, and concentrating the lysine-containing elution liquid with the reverse osmosis membrane system such that ammonia is selectively removed from the lysine containing elution; the aqueous ammonia which is separated from the lysine may be recycled through the cation exchange resin to regenerate the resin or to elute more lysine from the resin.Type: GrantFiled: December 24, 1984Date of Patent: July 22, 1986Assignee: Ajinomoto Co., Inc.Inventors: Tetsuya Kaneko, Masaru Saeki, Kiyoshi Tanaka, Tetsuya Kawakita
