为确保大庆油田稳产增收,聚合物扩能工程启动,丙烯酰胺国产化生产。在丙烯酰胺生产过程中,由于其性质不稳定易聚合,会造成反应器及精制塔聚合倾向,对生产造成巨大影响,同时降低了产品质量,且增加了生产成本。由于装置国产化,面临的任务更加严峻。在丙烯酰胺生产过程中:氧气即是聚合的引发物,又可作为阻聚剂,在反应系统由于氧气的存在使铜催化剂氧化引起丙烯腈和丙烯酰胺的自由基聚合,而在浓缩系统高浓度的丙烯酰胺溶液易聚合,溶解氧是聚合反应的阻聚剂。
In order to ensure a steady increase of output in Daqing Oilfield, the project of polymer expansion project started and acrylamide was domestically produced. In the process of acrylamide production, due to its unstable nature, it tends to polymerize, causing the polymerization tendency of the reactor and the refining tower, greatly affecting the production, reducing the product quality and increasing the production cost. As the device localization, the task facing more serious. In the acrylamide production process: oxygen is the initiator of polymerization, but also as a polymerization inhibitor, in the reaction system due to the presence of oxygen oxidation of copper catalyst caused acrylonitrile and acrylamide free radical polymerization, and concentrated in the high concentration system Acrylamide solution is easy to polymerize, Dissolved oxygen is a polymerization inhibitor.
