Correlation accurately predicts hydrate forming pressure of pure components

Gas hydrates are a well-known problem in the oil and gas industry when they agglomerate and plug pipelines and process equipment. This paper presents a new correlation that predicts hydrate formation pressure of pure alkanes, acid gases and nitrogen as a function of molecular weight at a given temperature. This correlation covers a temperature range between 263 and 293 K. The results show an average absolute deviation of 3.06% from typical experimental data for light alkanes and 1.4165% for nonhydrocarbons. The average absolute deviation for all data used in this work is 2.24%. The new correlation can be improved if more experimental data will be available in future.
