Determination of Methane‐Hydrate Phase Equilibrium in the Presence of Electrolytes or Organic Inhibitors by using a Semi‐Theoretical Framework
Abstract A thermodynamic‐based procedure was developed that is capable of predicting the incipient hydrate dissociation temperature in the presence of a single electrolyte or organic inhibitor aqueous solution. In the proposed framework, the two‐suffix Margules activity model is used to take into ac...
