Patent number: 9833740Abstract: A process of removing SO2 from a flue gas with a trickling filter using modified ceramsite packing is described. The biological flue gas desulfurization process includes: feeding the flue gas containing sulfur dioxide through the column bottom into the biomembrane trickling filter at certain temperature, contacting with the modified ceramsite biomembrane packing and purifying, which purified flue gas is discharged via the column top; and spraying the nutrient fluid rich in high concentration of the desulfurization strain through the top to the modified ceramsite biomembrane packing, thereby the sulfur-bearing pollution source in the flue gas is degraded, so as to discharge a purified flue gas satisfying the environmental requirements.Type: GrantFiled: June 18, 2014Date of Patent: December 5, 2017Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, RESEARCH INSTITUTE OF NANJING CHEMICAL INDUSTRIAL GROUPInventors: Aixiang Hao, Songbai Mao, Jing Kong

Publication number: 20140371483Abstract: A process for preparing methylene bis-(dialkylamino-dithioformate) in one step includes: simultaneously feeding all or part of four raw materials: dialkylamine, an aqueous solution of sodium hydroxide, dichloromethane and carbon disulfide through a constant-flow pump into a continuous flow reactor; performing the reactions in the continuous flow reactor under a temperature of 10 to 100° C. and with a residence time of 10 to 100 s; simply separating of the obtained reaction products to give the final product. The process synthesizes the product in one step by using the continuous flow reactor. The rapid mass transfer and heat transfer in the continuous flow reactor promote the main reaction, reduce side reactions, improve the product color, and shorten the operation time. Moreover, the yield is relatively high and the quality of the final product meets the requirements.Type: ApplicationFiled: June 18, 2014Publication date: December 18, 2014Applicants: CHINA PETROLEUM & CHEMICAL CORPORATION, RESEARCH INSTITUTE OF NANJING CHEMICAL INDUSTRIAL GROUPInventors: Zhiyong HE, Wei Huang, Weiwei Kong, Lei Ren, Junyan Ping
