Patent number: 6254771Abstract: This invention relates to a method for the treatment of a desulfurization absorbing fluid after gas-liquid contact with combustion exhaust gas in which fine particles of unburned carbon and other materials are efficiently removed from the desulfurization absorbing fluid to improve the quality of a by-product (e.g., gypsum) obtained therefrom. The method of this invention comprises the steps of feeding a gas into a desulfurization absorbing fluid (A) containing fine particles of unburned carbon and other materials and thereby producing gas bubbles so as to cause the fine particles to adhere to the surfaces of the gas bubbles and create a foam phase (D) consisting of the gas bubbles; and breaking the foam phase (D) to obtain a liquid (E) containing the fine particles.Type: GrantFiled: August 4, 1999Date of Patent: July 3, 2001Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Koichiro Iwashita, Takeo Shinoda, Masakazu Onizuka, Masao Hino, Kenji Inoue

Patent number: 4853194Abstract: A method for treating an exhaust gas which includes leading a coal-fired exhaust gas to a dry denitrating device, removing oxides of nitrogen from the exhaust gas in the device, leading the exhaust gas to a dry electric dust collector and a wet waste smoke desulfurizing device disposed at downstream positions, and removing dust from the exhaust gas in these devices. A sodium compound containing solution is sprayed into the exhaust gas flowing between the dry denitrating device and the dry electric dust collector thereby increasing the efficiency of the dust collector, and the resulting dry solids are then collected together with the dust by the dry electric dust collector.Type: GrantFiled: February 24, 1987Date of Patent: August 1, 1989Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Masao Hino, Kenichi Yoneda, Masato Miyake, Hidehiko Otani, Noriya Shingu, Tsukasa Isahaya, Shigeshi Hamada, Tsuyoshi Arahori
