Abstract

In this study, two new correlations are proposed to predict the natural gas hydrate formation temperature as a function of pressure and specific gravity. The first correlation has been developed using Vandermonde matrix and the coefficients of the second correlation have been obtained by Levenberg-Marquardt algorithm. The error analysis shows the good performance of the two new proposed correlations to predict hydrate formation temperature compared to correlations presented earlier and also the experimental values.
