Hello, in a PCT curve, we have two absorption and desorption curve , here assume we have a constant concentration at a straight vertical line. I would like to know what equations we can use to calculate the amount of heat for the process, The image give will assist in understanding the question. There is a straight line CE which is vertical, how can we calculate the heat required on line CE , assume we know the low pressure (PL), low temperature(TL), high-pressure(PH) and high temperature(HT), and a constant concentration line (CC), what equations we can used??

Any assistance as early as possible would be appreciated !

I would also like to know if there is a document/paper or book covering the mathematical understanding of the PCT Curve considering the equations and other parameters and understanding the modeling of the curve.
