See below for a calculator which predicts the hydrate formation temperature of natural gas systems. Sharing in case someone needs it

Hi,

Thanks for sharing.

Very Interesting! Have you compared your results to the hydrate predictors in the top commercial process simulators? I never found a method I trusted completely. I think the biggest problem I had was accounting for the effects of individual components other than the simplified component lumping. In designing process temperatures, I tried to err on the conservative side by using more than one prediction method. In diagnosing plant problems for suspected hydrate formation, it was difficult to completely trust any calculation result that gave assurance the temperature was above the hydrate formation temperature.

An additional feature you may want to incorporate in your spreadsheet is to include the reference citation for the methods you are implementing.
For additional comparison, see the spreadsheet contributed by Ankur (who used to be quite active here.)
Four methods for hydrate prediction are compared in that spreadsheet.

Thanks for the contribute,

You may consider also online calculators to verify your results

Thanks all for the comments. I developed this tool to determine the impact of H2S on the hydrate formation temperature after observing my gas injection chokes being plugged. The results are a good estimate regarding the relationship however the chemical vendor and specialist should be consulted as part of the treatment program.
