Densities of compressed liquid methane, and the equation of state

Abstract

Experime ntal PVT data for liquid methan e are reported at densiti es from 1.8 tim es criti cal up to the freezing Liquid , at tem perature s from 91 to 245 K a nd press ures to 350 bar. A nonanalytic equation of state is adjusted to these and other PVT data from id eal gas states to th e free zin g liquid , at tempe ratures from the tripl e poin t to 400 K.
