Experimental and smoothed data are presented for the solubility of methanein water for temperature, of 77, 100, 160, 220, 280, and 340?F at pressures to10,000 psia.
The minimum solubility phenomenon exists within this temperature range topressures of 10,000 psia.
The study of hydrocarbon-water systems has been extended to thedetermination of the solubility of methane in water at pressures to 10,000psia. The experimental apparatus and the technique, are the same as thatpreviously reported.
In the determination of the solubility of methane in water, only two phaseswere present at temperatures between 100 and 340?F, these being the vapor phaseand the water-rich liquid phase. The determinations involved the agitation ofmethane and water in an equilibrium cell, withdrawal of a sample from theliquid phase, and the analysis of the sample. The experimental valuesdetermined in this manner are presented in Table I and in Fig. 1.
Since experimental and analytical techniques have improved since the initialexperiments with this equipment, it was decided to repeat the 77?F isothermdeterminations. Fig. 1 shows that the individual results for this isotherm aremuch more nearly consistent than the data previously reported.
