| Summary: | Prediction of natural gas phase behaviour is important and crucial in hydrocarbon processing industries. This paper main objective is to predict phase envelope of natural gas mixtures by using eight equations of state functions and hence to look at its applicability by comparing the predictions of temperature and pressure from the experimental values conducted for 24 set of natural gas mixtures that comprise of lean natural gases or synthetic natural gases. Hence, the studies of Van der Wall (VDW) and Wong Sandler (WS) mixing rules used with EOS functions are discussed in terms of its significant and validity of the equations to the calculated results. The resulted calculation values of T and P was calculated by using Prode add in Microsoft Excel simulator. For a conclusion, it is found that Soave-Redlich-Kwong (SRK) families with VDW mixing rules have wide applications and are superb in predicting phase behaviours of different mixtures with 83% dominant level compared to Peng-Robinson (PR) families with WS mixing rules when tested for 24 set of natural gas mixtures data. |
