辽阳石油化纤公司已二腈生产装置系采用法国隆波利公司专利,是以过量氨与熔融已二酸在催化剂磷酸和稀释剂存在下进行反应的连续化生产工艺。腈化反应器是生产已二腈的关键设备,其结构和工艺参数见图1和表1。物料流程如下:熔融已二酸、磷酸、稀释剂由底部进人。循环和补充的氨气以及从膜式蒸发器回来的气体,由腈化反应器顶部的中心管进入
Liaoyang Petrochemical Fiber Company has dinitrile production line with the French company Polyconi patent, is excessive ammonia and molten adipic acid catalyst in the presence of phosphoric acid and diluent in the continuous reaction of the production process. The nitrile reactor is the key equipment for the production of dinitrile. The structure and process parameters are shown in Figure 1 and Table 1. Material flow is as follows: molten diacid, phosphoric acid, diluent from the bottom into. Ammonia gas, circulated and supplemented, and gas returned from the membrane evaporator are introduced by the central tube at the top of the nitrification reactor
