NAOH吸收SO2 填料塔？ 下面是模拟结果，气相：so2 58m3/h，n2 32226m3/h,温度 293k,压力101kpa. 液相：30%的氢氧化钠溶液150m3/h，温度 293k,压力104kpa 塔板数：15. 拉西环填料 顺便问一下，aspen能否直接计算填料高度，就像简捷法计算塔板数一样。现在用的是先估算塔板数，再根据塔板数与填料的等量高度，计算填料高度。实际中我若是能够估算准塔板数，就不用aspen计算了！ - calculations begin ... ** error radfrac not converged in 25 outside loop iterations. *** severe error material and energy balances failed to converge: check col-specs or supply better temperature and composition estimates. * warning in physical property system attempt to use model elecnrtl without a solvent. activity coefficient of unity is used * warning in physical property system attempt to use the clarke aqueous electrolyte density model without a solvent. calculation not performed. * warning in physical property system attempt to use the clarke aqueous electrolyte density model without a solvent. calculation not performed. ** error h-loop does not converge in 5 trials. energy balance not satisfied within maximum number of iterations. ** error flooding calculations for section (1) failed to converge. calculated diameter may not be accurate. ** error pressure drop calculations failed to converge. pressure drop calculated for section (1) may not be accurate. ** error block absorbe is not in mass balance: mass inlet flow = 0.48206959e+04, mass outlet flow = 0.48044435e+04 relative difference = 0.33827761e-02 * warning stream naoh is not in charge balance: anion flow = -.50342386e+00, cation flow = 0.51602005e+00 relative difference = 0.25021041e-01 * warning stream w is not in charge balance: anion flow = -.67645052e+01, cation flow = 0.95116797e+01 relative difference = 0.40611611e+00 - simulation calculations completed ... *** severe error fortran overflow encountered. ** error flooding calculations for section (1) failed to converge. calculated diameter may not be accurate. ** error pressure drop calculations failed to converge. pressure drop calculated for section (1) may not be accurate. * warning vlstd missing for component sodiu(s). calculated stdvol flow will be incorrect. *** severe error fortran invalid operation encountered. convergence iterations: ol ml il err/tol 1 1 1 0.24254e-09 2 1 1 0.23979e-09 3 1 1 0.94145e-11 *** severe error material and energy balances failed to converge: check col-specs or supply better temperature and composition estimates. *** severe error the following stages dried up: 13 a limit of 0.10000e-04 * sum of feeds was imposed on the flow rates. * warning in physical property system attempt to use model elecnrtl without a solvent. activity coefficient of unity is used * warning in physical property system attempt to use the clarke aqueous electrolyte density model without a solvent. calculation not performed. * warning in physical property system attempt to use the clarke aqueous electrolyte density model without a solvent. calculation not performed. ** error h-loop does not converge in 5 trials. energy balance not satisfied within maximum number of iterations. ** error block absorbe is not in mass balance: mass inlet flow = 0.48206959e+04, mass outlet flow = 0.12609178e+08 relative difference = 0.26146345e+04 * warning stream naoh is not in charge balance: anion flow = -.50342386e+00, cation flow = 0.51602005e+00 relative difference = 0.25021041e-01 * warning stream w is not in charge balance: anion flow = -.67644409e+01, cation flow = 0.95115894e+01 relative difference = 0.40611611e+00 - simulation calculations completed ... - generating report ...查看更多
