Problem Statement: When running the same file in V2006.5 and V7.3, there are different results for the RadFrac distillation column block reboiler temperature. In V2006.5, the temperature is 89.4°C and in V7.3, without any input change, the value for the reboiler temperature is 90.7°C. When simulating a reboiler, 1°C of... | Solution: We made some changes to the thermosiphon reboiler, which caused different results between 2006.5 and V7.3. When the return liquid from the thermosiphon reboiler is mixed with the liquid from the last stage, there might be some vapor generated from the mixing. This is not considered in 2006.5, but was taken in... |
