物性方法选择？ 做一个塔，含有如下的物质：甲醇、甲酸甲酯、丙酮、甲基乙基酮、二乙基酮、醋酸、丙酸、乙醛、乙醇、醋酸甲酯、乙酸乙酯、水、甲酸应该选择什么模型。 选了prws，还试了很多其他常用的物性方法，都是有相同的警告提示，不知道是不是因为物性方法的问题 ，如果不是请指教，是的话请推荐一个合适的方法，谢谢： processing input specifications ... * warning in the "properties" paragraph which begins on line 65 free-water method should be steamnbs when the main property method is srk. default free-water method is steam-ta please specify the recommended free-water method and run again. information binary parameters prkij (data set 1) for model esprstd are retrieved from sdf table. table name = esprstd * warning in the "stream" paragraph which begins on line 268 stream name: feed component mass fractions are normalized to unity. * warning in the "stream" paragraph which begins on line 276 stream name: steam component mole flows of substream: "mixed" are normalized to the total mole flow value. * warning in physical property system equation of state model polysl has missing parameters: slpstr (data set 1) missing for component methanol a nominal value of 3000.
