基于系统集成的复杂催化反应系统性能强化及参数优化
Performance enhancement and parameter optimization of complex catalytic reaction system based on system integration
摘要
Abstract
For the catalytic reaction system,the reactor acts as the core of material conversion,and its key lies in selecting highly active catalysts.During production,catalyst activity decreases with the passage of operating time,affecting the reactor performance and the operation of subsequent devices.Clarifying system parameters'changing rules and making corresponding deactivation compensation measures is of great significance in strengthening system performance and reducing production costs.Based on separable reaction kinetics and mass/energy balance,correlation models targeting the relation between the reaction performance,reactor operating parameters,and running time are established.According to the topology analysis,pinch analysis,and cascade effect analysis,the time-varying law of each device's and system's energy requirement is revealed.On this basis,an economic evaluation index considering system integration is constructed to guide catalyst regeneration and system parameter optimization.A benzene selective hydrogenation to cyclohexene process is taken as an example,with the system performance/operating parameters'time-varying characteristics visually displayed.The catalyst's optimal regeneration cycle is determined as 1.92 a.Compared with the literature results,the optimized service life is closer to the engineering value,with the average production cost per unit product reduced by 5.2%.关键词
