Method and device system for producing dimethyl oxalate through midhigh and high-pressure carbonylation of industrial synthesis gas and producing ethylene glycol through dimethyl oxalate hydrogenation |
| abstract |
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, O 2 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. The system comprises an esterification reaction system, a carbonylation reaction system, a purge gases and waste acid coupling recovery system and a hydrogenation reaction system. |
