Publication number: 20170267615Abstract: A method and a device system for producing dimethyl oxalate through high-pressure carbonylation of industrial synthesis gases and producing ethylene glycol through dimethyl oxalate hydrogenation. The method comprises the following steps: adopting industrial NO, O2 and methanol as raw materials to perform an esterification reaction to produce methyl nitrite, then adopting industrial CO and methyl nitrite to perform a carbonylation reaction in a plate reactor to produce carbonylation products which mainly include dimethyl oxalate and dimethyl carbonate, separating the carbonylation products to obtain dimethyl carbonate products, and subsequently performing hydrogenation to dimethyl oxalate in the plate reactor to produce ethylene glycol products; and performing coupling recovery treatment to waste acid in the esterification reaction and purge gas in the carbonylation reaction for recycling.Type: ApplicationFiled: July 23, 2014Publication date: September 21, 2017Inventors: Baoming WANG, Donghui WANG, Yujiang LI, Changqing XU

Publication number: 20170267617Abstract: A method and a system for recycling spent ethylene or propylene glycol recovered from aircraft deicing solutions is described. The recovered spent ethylene or propylene glycol contains water and other undesirable substances which require to be removed to produce a solution free of these substances which can be further processed to remove substantially all of the water content and to blend-in additives required to certify the final glycol solution for aircraft deicing. The method and system employs a computer controller for continuous automatic batch processing of the spent glycol, including, in combination, filtering, distillation, blending and testing in specific sequences and achieves an improved quality recycled glycol of a purity of at least 99.5% and preferably between 99.6% to 99.9% glycol concentration.Type: ApplicationFiled: March 17, 2016Publication date: September 21, 2017Applicant: AÉRO MAG 2000 RRR INC.Inventors: Mario Lépine, Ghislain Bergeron, Michel Guy
