Hello,
I am wondering what the purpose of the Ponchon Savarit method is for determining the theoretical number of stages using an enthalpy-concentration diagram. From what I am seeing, the method requires using a xy diagram with the equilibrium curve. Isn't it superfluous to use the H-x diagram when it needs the xy diagram which is already finding the number of stages with the McCabe-Thiele method?
The crux of my question is if the H-x diagram can be used in isolation to find the number of stages for a separation?
Edit:
Or rather it seems, at least if you are not given the tie line for the H-x diagram, then you would need the x-y diagram to find the tie line. So I guess I should rephrase my questiion, "In the absence of a tie line on a H-x diagram, is it superfluous to use the Ponchon-Savarit method to find the number of stages for a separation, when the McCabe-Thiele diagram is necessary to even construct the diagram?" and "Can a H-x diagram be used in isolation to find then number of stages for a separation in the absence of a tie line?"
Thanks
