求大神指教，我想用吉布斯反应器模拟一个含有cas（硫化钙）和caso4（硫酸钙）的反应，可是调试有这些问题，到底是怎么回事呢？谁能帮帮我

物性方法你用的什么

用的PENG-ROB，我现在的问题是，想把气固混合物分离开来，一路走气体，一路走纯固体，但是不会用solid模块，结果分离不开

不明白你的工艺情况，无能为力帮助你。

如果单纯的气固物流分离的话，试用一下sep模块看怎么样

sep模块不都是气液分离么？没有气固分离的模块啊

Cyclone, ESP.气固分离的

用 Sep 模块分离不就行了吗！！！用通用过程就行吧，应该。。。

用旋风分离器就可以

前辈，您好，很冒昧打扰您！我在帖子里看到您做了硫化钙、硫酸钙的固体反应模拟，所以想请教您一个一直困扰我的问题，我想模拟硫酸钙、半水硫酸钙、二水硫酸钙分别在不同浓度氯化铵溶液中溶解度随温度的变化关系，但是我条件输入完成后总会出现报错，显示我这边缺少相关固体的物性参数导致计算中止。所以我想请教一下您在您模拟的反应过程中是怎样定义硫酸钙以及含有硫酸钙的固体混合物？求求大佬解惑

反应器选择的不对吧，你试试其他反应器

反应方程是什么？条件是什么？没明确。
