Hi all,

Does anyone what the Wichert-Aziz pseudocritical temperature correction factor (GPSA Figure 23-8) is based on? Is it experimental or is there a relation? I would like to build some code to automatically calculate this factor if possible. GPSA says that this figure is from Wichert, E. and Aziz, K., Hyd. Proc. 51, 199 (may, 1972), but I have been unable to find this document. Does anyone know where I can find this? For anyone who is not familiar with this, this factor is used to correct the compressibility factor for presence of CO2 and H2S. If there is not a relation I guess I will have to tabulate this figure some how.

Any input is greatly appreciated.

Thanks,

Chad
