When simulating a distillation column and encountering problems, a simplified design for the distillation column is used
Thread Content
The K value for the key light component in the distillate is 0.45009E-55, with a distillation temperature of 24.694. It is impossible to calculate the minimum series. No calculation is performed. The DSTWU module is used, enabling a simplified design of the distillation tower
Overall, there are no mistakes. Is the light component recovery rate input too high?
The actual reflux ratio is 1.8 times the minimum reflux ratio; the recovery rate of the light key component is 89%, and that of the heavy key component is 98%. The reboiler operates at 0.5 MPA, the condenser at 0.3 MPA; the key components separated by the distillation column are n-pentane and butane. Then the error is still displayed. At a distillation temperature of 24.684, the k value for the light key component in the distillate is 0.42454E-55. It is impossible to calculate the minimum series. Calculation bypassed. We have a flash tower ahead; flow data was entered previously. When proceeding with DSTWU, we were not asked to enter the temperature and pressure of the distillation tower, nor the property data of the material after the first stage of hydrogenation
