Study On Expanding Capacity Technics For PTA Plant

PTA is raw materials of the polyester, in recent years, with domestic polyester device capacity to the rapid development, manufacturing plants have a pta expanding capacity technology research. This article to share the chemical fibre yizheng pta setup some of the bottleneck problems relevant research, expanding capacity reform measures, the essay for complex px catalytic oxidation of the need for simplification and a reasonable decompose. Successfully built that contains a catalyst for broad influence of the reactor kinetic model. This model is not only contain reactions and operating materials, but a catalyst and a vehicle for the role of the catalyst. In different levels, different raw materials proportion and processing of cases, the calculations of the reactor of state and the overall running state, made suggestions to the reactor expanding capacity. Paper to oxidation reactor system and the condensers fine glow of the unit to feed the heat, the number of republican aspen plus chemical process simulation software accounting of its heat exchange capacity, by 20% of the main change expanding capacity heater system reform. The paper analyzes the water tower of the solvent status and bydrodynamic characteristics determine a solution to the overall water tower, Make the proposals of 20% expanding capacity and provide the relevant data.
