Underwoods equation
Web3 Apr 2024 · I've received errors that say that the bubblepoint calculation timed out after 16 iterations, that the minimum reflux ratio calculated with the underwood equation is negative and is being set to 0.1, not converging within 25 iterations, etc. I've played around with the values a lot to try to get it to work. WebPlease for the derivation of the Underwood's equations, see the attached pdf file. Calculation of the finite reflux. The further step is the calculation of the finite reflux. This is done, as for the binary case, using a multiplying factor, as follows: R = (1.05 - 2) R. min
