  • Patent number: 7977513
    Abstract: An amine producing apparatus includes a reactor that reacts a mono-lower-alkylamine and an alkylene oxide, an unreacted-raw-material-recovery distillation column that separates unreacted raw materials by distillation from a product including unreacted raw materials obtained in the reactor, a non-aqueous distillation column that removes water and a light component by a distillation method from a reactive product from which unreacted raw material have been separated, and a purification and distillation column that separates by distillation a desired reactive product (mono-lower-alkylmonoalkanolamine) and residue (mono-lower-alkyldialkanolamine which is a dimer) from a reactive product from which the water and the light component have been removed.

  • Patent number: 6423282
    Abstract: A method for the regeneration of an acid gas absorbing fluid which comprises bringing a gaseous mixture containing an acid gas such as, for example, gasified coal gas, synthesis gas, coke oven gas, petroleum gas, natural gas, and the like, into contact with an absorbing fluid containing methyldiethanolamine and a (lower alkyl)piperizine such as, for example, 2-methylpiperazine or 2,5-dimethylpiperazine, so as to absorb the acid gas into the absorbing fluid, and regenerating the absorbing fluid by releasing the acid gas from the absorbing fluid by releasing the acid gas from the absorbing fluid in a regeneration tower having a temperature of not less than 40° C., preferably from 40° C. to 80° C.
