用Aspen Properties计算固体在液体水中的溶解度? 1# lsrwan “true component approach是允许输入离子浓度的”赞同楼主的观点。 aspen10.0电解质英文说明书中有如下表述: when you use the true component approach, aspen plus solves the equations describing solution chemistry simultaneously with the unit operation equation the unit operations deal directly with the ions and salts formed by solutionchemistry. in addition, the true component approach defines how aspen plus reports the simulation results. results are reported in terms of the ions, salts,and molecular components that are actually present, not in terms of the origin base components. for example, the generated chemistry for this system specifies that naoh fulldissociates into na+and oh-. if you choose the true component approach, aspen plus will report naoh flow in terms of na+flow and oh-flow, not interms of the naoh base component flow. you can request that composition and flows also be reported in terms of the apparent (base) components.查看更多
