Predicting CO₂ hydrate forming conditions in the presence of inhibitors and electrolytes

A combining rule for calculating hydrate formation temperature in the presence of both electrolytes and alcohol (glycol) has been developed. The hydrate temperature in the presence of pure water is calculated; this temperature is then separately corrected for the presence of electrolytes and alcohols. The average of the absolute temperature deviations for predicting hydrate forming conditions for CO₂ in mixtures where both electrolytes and alcohols (glycols) are present was 0.41 K.
