基于ASPEN PLUS用户模型技术的催化重整全流程模拟

Simulation of industrial catalytic reforming process by developing user’s module on ASPEN PLUS platform

采用用户模型技术,将自主开发的17集总反应动力学模型与ASPENPLUS稳态流程模拟软件集成在一起,从而在ASPENPLUS平台实现了包含重整反应装置在内的催化重整全流程模拟.这一技术既可以利用ASPENPLUS强大的数据库、模型库和模拟优化功能,大大拓展模拟范围,又可以保持自定义反应模型的特点.整个流程全部仿照反应动力学模型,将300多种化合物定义成18种集总组分(含氢气),并采用专用于石油系统的物性计算方法.建立的ASPENPLUS二次开发软件在某连续重整装置上获得了成功应用,模拟结果与实际操作值吻合得相当好,完全满足工业应用的要求.此软件可用于催化重整装置的生产调优、扩能改造和新装置的工艺设计.

The industrial catalytic reforming process is simulated by developing the seventeen lumped kinetics model as a user module on ASPEN PLUS platform. The technique of user＇s module utilizes the strong databases, complete sets of modules, and flexible simulations tools of the ASPEN PLUS system and retains the characteristics of the self-developed model. Eighteen lumped components （including hydrogen） are defined for more than three hundred compounds in the flowsheet, and special property methods suitable for the petroleum system are selected for the simulation. The developed simulation software is applied to a commercial continuous catalytic reforming process successfully. The simulation results show that fair agreements between the calculated and actual operating data are obtained.
