Abstract
The reliability of prediction models in determining hydrate forming temperatures adequately is of
paramount importance. Most correlations have been found to vary significantly from experimental
hydrate forming temperature data. This study is focused on developing correlations for predicting
vapour solid constants for methane, ethane, propane, iso – butane, normal – butane, carbon IV
oxide and hydrogen sulphide by extracting over 2000 data points from the GPSA chart. The
correlations developed in this study were used to develop a computer program for predicting
natural gas hydrate formation temperatures for mitigating the challenges posed by natural gas
hydrate formation in process installations. The correlations gave correlation coefficients between
0.9 and 0.99. The computer model developed gave an average relative error of -3.73%, coefficient
of correlation of 0.94 and a standard deviation of 5.9%.
