The formation of gas hydrates in oil & gas pipelines and drilling fluid flow lines is a major issue in the petroleum industry. Gas hydrate inhibitors are normally used to inhibit the formation of gas hydrates in the pipelines/flowlines. Initial screening of hydrate inhibitors and AntiAgglomerants (AA) requires a safe and economical experimental setup/method. Conventional visual method was used for initial screening of hydrate inhibitors in many researches. Some researchers also suggested modified visual methods, but all of them lacks accurate measurement of induction time and found to be inappropriate for experimental solutions like drilling mud, etc. In this work, a temperature augmented visual method was presented which can be used in academic research laboratories for study and initial screening of hydrate inhibitors. This method is capable of parallel screening of inhibitors and determines hydrate induction time precisely. Experiments were conducted to determine the hydrate induction time of different inhibitors using augmented method and compared with conventional visual method. The developed method found to be more precise in determining the induction time of hydrates in all types of experimental solutions.

Thermodynamic Equations

An experimental study has been made of the saturation pressure – temperature lines of liquid bromochlorodifluoromethane, liquid bromochlorodiflucromethane – water, bromochlorodifluoromethane hydrate – water, and bromochlorodifluoromethane hydrate – ice systems, for which the characteristic equations are given. Two quadruple points for the hydrate systems have been located and solubilities of water in bromochlorodifluoromethane and bromochlorodifluoromethane in water determined. A systematic treatment of gas hydrate saturation pressure data to yield thermodynamic equations is indicated, and the thermodynamic functions for bromochlorodifluoromethane hydrate and its phase reactions are tabulated. Bromochlorodifluoromethane hydrate is shown to be a stoichiometric compound, and its thermodynamic functions are considered in relation to those of other gas hydrates.
