Predicting natural gas hydrate formation temperature using Levenberg-Marquardt algorithm

By J Sayyad Amin, Alireza Bahadori, E Mohamadi and B Hoseini Nia


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
