From the developer:
Hydrate Plus allows the user to predict hydrate formation temperatures and minimize inhibitor injection costs with one easy-to-use utility! Provide Hydrate Plus with a gas composition and you can plot Hydrate formation curves, or solve directly for the hydrate formation temperature or pressure.
Hydrate conditions can be calculated based on the widely accepted Baillie-Wichert method, or the Mann et.al equilibrium method.
