The process design of annual output of 100000 tons of acrylonitrile

Abstract: Acrylonitrile is a very important chemical materials。Many chemical products and materials synthesized by it are widely used in many fields。 This is the process design of annual output of 100000 tons of acrylonitrile。 The design used in ammonia oxidation of propylene method。 This method have many advantages,such as the simple production process,the high purity of product,the low costs of investment。 In this design, the process status of domestic and foreign,nature,use and production method of acrtlonitrile are simply introduced。 The design focus on calculating the reaction section of the acrylonitrile synthesis section and the recycling and refining sections are also simply designed。The process conditions include reaction temperature, reaction pressure, contact time, raw material purity。The reaction principle is main, side reaction and catalyst。The reaction was carried out by using liquid propane, liquid ammonia, air and water vapor as catalyst and CAT-6 as catalyst。The annual production capacity and raw material flow rate of acrylonitrile are calculated by material balance。The design also conducte a thermal balance as well as the design and calculation of the equipment are selected。This design mainly involves the synthesis section, the recovery section and the refining section and choose the main tower equipment for the process and equipment design。
