Abstract
The use of gas-lift lines for thermodynamics inhibitors injection to prevent hydrates formation may be a practical solution for wells already operating. However, as these lines are designed for gas only, the presence of liquids above certain quantities may damage some valves, indicating that these chemicals must be dissolved into the gas phase. Thus, it is important to know the phase envelope of the mixture of natural gas and thermodynamic inhibitor. Since methane is the main component of natural gas and one of the most used gas hydrate inhibitor is the ethanol, the system methane + ethanol will be experimentally investigated in pressures up to 100 bar and temperatures up to 353,15 K, with global composition between 94 % and 98 % of methane, in order to determine the dew point of theses mixtures. The synthetic isothermal experimental methodology will be applied and three different techniques will be utilized to properly determine the dew point: visual, acoustic and graphical. The experimental results will be used to tune the binary interaction parameters for the thermodynamic modeling using CPA equation of state.
