Analysis Of Acrylonitrile Production Of Energy Saving Measures

Acrylonitrile is three synthetic materials (fibers, rubber, plastic) is an importantchemical raw materials, mainly used in the production of polyacrylonitrile (Pan), ABS/SANresin, acrylamide, adiponitrile, styrene, carbon fiber. Acrylonitrile in1893by the Frenchchemist was prepared, until the nineteen forties began industrialized production. In1960, BPsuccessfully created by the propylene, ammonia and air in heterogeneous catalysis in afluidized bed reactor in the acrylonitrile direct oxidation of ammonia manufacture newtechnology. At present domestic acrylonitrile mainly manufacturers have Shanghai China Petroleumand chemical division of Formosa Petrochemical Co; Sinopec Qilu Company acrylic fiberplant; China Petroleum Daqing petrochemical chemical plant two; China Petroleum DaqingPetrochemical polymer factory; China Petroleum Lanzhou Petrochemical Company chemicalplant; China Petroleum Fushun Petrochemical Co factory of acrylic fibbers of acrylonitrileplant; PetroChina Jilin Petrochemical Co; Sinopec Anqing Branch Ministry of acrylonitrile;Sinopec Shanghai Secco Petrochemical Limited liability company9, which in addition toShanghai petrifaction of acrylonitrile plant was built in70years, the remaining8sets werebuilt in the90’s of acrylonitrile unit. I plant the production of acrylonitrile:source of raw material propylene (100%meter):year need quantity is111194tons,300000tons/year ethylene plant by auspicious changesafter the expansion of supply. The original design for pipeline into the project, is still usedpipeline input. Liquid ammonia (99.3%meter):year need quantity is54007tons, supply byJilin fertilizer plant, the original design through pipelines to the project, is still used pipelineinput. Sulfuric acid (100%meter):year need quantity is9964tons, the original design in theJilin area for railway tanker procurement, transported to the existing base station, is still in thenorthern region procurement, with the railway tank cars delivered to the existing base stationand supplied to users. Oxygen (air gauge:20%) by the air compression station aircompressor to generate. This paper mainly introduced the effect of acrylonitrile production of raw materialpropylene, ammonia consumption factor, and find out the control measures. And a variety ofwater, electricity, gas and other energy consumption control measures. Maximally reducematerial and energy consumption, to achieve the purpose of energy saving. Productionprocess optimization. Through comprehensive analysis and draw the conclusion on thepurification recovery of key equipment quench tower transformation, from the current twosegment into a tower structure. In order to improve the yield of acrylonitrile.
