aspenplus能对理论塔板数进行敏感分析吗？ 为甚么我每次做都做不出来，但做压力或组成的敏感分析都可以。

可是还是无法收敛啊，是不是我什么地方出错了！我用的radfrac,物性方法为nrtl！是不是进入第二个塔的进料压力要设定啊，也就是他的v2是不是要设定压力！错误是这样的大体上： ->calculations begin ... block: v2 model: valve ** error outlet pres (= 0.50662e+06) spec is greater than the the inlet stream pres (= 0.10810e+06) block: c2 model: radfrac convergence iterations: ol ml il err/tol 1 5 17 0.86886e-02 > beginning convergence loop $olver01 method: secant block: v2 model: valve ** error outlet pres (= 0.50662e+06) spec is greater than the the inlet stream pres (= 0.10810e+06) block: c2 model: radfrac convergence iterations: ol ml il err/tol 1 4 14 0.71135e-02 > loop $olver01 method: secant iteration 1 1 vars not converged, max err/tol -0.30124e+01 block: b6 model: fsplit block: v1 model: valve block: c1 model: radfrac convergence iterations: ol ml il err/tol 1 5 19 0.55863e-02 block: v2 model: valve ** error outlet pres (= 0.50662e+06) spec is greater than the the inlet stream pres (= 0.10810e+06) block: c2 model: radfrac convergence iterations: ol ml il err/tol 1 4 14 0.32036e-02 > loop $olver01 method: secant iteration 2 1 vars not converged, max err/tol -0.42180e+01 block: b6 model: fsplit block: v1 model: valve block: c1 model: radfrac convergence iterations: ol ml il err/tol 1 5 19 0.10344e-01 block: v2 model: valve ** error outlet pres (= 0.50662e+06) spec is greater than the the inlet stream pres (= 0.10810e+06) block: c2 model: radfrac convergence iterations: ol ml il err/tol 1 5 17 0.26754e-01 > loop $olver01 method: secant iteration 3 1 vars not converged, max err/tol -0.59461e+01 block: b6 model: fsplit block: v1 model: valve block: c1 model: radfrac convergence iterations: ol ml il err/tol 1 5 15 0.52741e-01 block: v2 model: valve ** error outlet pres (= 0.50662e+06) spec is greater than the the inlet stream pres (= 0.10810e+06) block: c2 model: radfrac convergence iterations: ol ml il err/tol 1 5 16 0.11486 > loop $olver01 method: secant iteration 4 # converged max err/tol 0.74327e+00 block: p12 model: pump block: v12 model: valve block: p11 model: pump block: v11 model: valve block: p22 model: pump block: v22 model: valve block: p21 model: pump block: v21 model: valve ->generating block results ... block: p12 model: pump block: p11 model: pump block: p22 model: pump block: p21 model: pump ->simulation calculations completed ... 附件为模拟的流程图 5# abingchem

燕山石化仿真中心很贵的，要5、6千，如果不是单位出钱让你培训，自己还是不要去，自学一下吧！

楼主看看是不是单位设置错了。把mol/h 选成kg/h了。

楼主好人

非内行，对课程设计不懂 哦，那为什么要做这个？

寻aspenplus模拟甲醇精馏过程题例 --------------------------------------------------------------- 最近在做用aspen模拟甲醇双塔和三塔精馏，有点困难，谁帮帮，谢谢

新的物料，aspenplus里没有的物料如何导入，需要哪些数据，最好有案例可以，：）
