Caprolactam production technological progress and project investment analysis

Yang Jun,Feng Meiping(Technology Center,SINOPEC Baling Petrochemical Company,Yueyang 414014)  
The caprolactam production technologies were briefly introduced.The latest progress in caprolactam production technology was described in detail,including butadiene process,cyclohexene hydration,cyclohexanone oxime gas-phase Beckmann rearrangement,cyclohexanone oximation.The ammoximation process and hydroxylammonium phosphate(HPO) process were compared and analyzed for caprolactam.It was pointed out that the ammoximation process had the characteristics of simple process,moderate conditions,low-level three wastes and low investment.The investment prospects of caprolactam projects were analyzed.It was put forward that SINOPEC should carefully conduct project evaluation in order to avoid risk while constructing a caprolactam project applying the cyclohexanone ammoximation process with the independent intellectual property or traditional cyclohexane route.
