摘　　要：吸收过程的模拟计算在化工流程模拟中具有重要地位。单独一种算法很难适用不同类型吸收过程的计算,因此,开发能计算不同类型吸收过程的复杂吸收塔单元模块具有重要意义。基于CAPE-OPEN标准,对复杂吸收塔单元模块进行开发,首先明确复杂吸收塔的功能,根据流量加和法、新松弛流量加和法建立数学模型及求解算法;其次,采用C++语言,通过COM组件技术开发吸收塔单元模块;最后,分别通过非极性体系和极性体系两个吸收实例对所开发单元模块进行测试。将计算出的各塔板温度、汽液相流量、组成与Aspen Plus计算结果进行对比,结果表明,除个别含量很小的组分组成相对误差较大外,其余各塔板温度、汽液相流量、组成相对误差均在0.3%以内,表明该单元模块计算结果准确可靠,对于吸收过程的模拟与优化具有重要的实际意义。It is acknowledged that the simulation of the absorption process plays an important role in the chemical process simulation. A single algorithm is difficult to apply to the calculation of different types of absorption processes; therefore, it is important to develop a complex absorption unit module that can calculate different types of absorption processes. Based on the CAPE-OPEN standard, the complex absorber unit module was developed, first clear the function of complex absorption tower, establishment of mathematical model and solving algorithm based on Sum-Rates method and new relaxation Sum-Rates method; Second, development of absorption tower unit module through C＋＋ language and COM technology; Finally, The developed modules were tested by two examples of non-polar system and polar system. The calculated plate temperature, vapor-liquid flow, composition are compared with Aspen Plus results, the results show, in addition to the small individual components of the composition of the relative error is relatively large, the remaining plate temperature, vapor-liquid flow, the composition of the relative error are within 0.3%. It is shown that the calculation result of the unit module is accurate and reliable, which is of great practical significance for the simulation and optimization of the absorption process.
