摘要: Abstract Phase boundaries between homogeneous liquid phase and two-phase regions, both liquid-vapour liquid-solid, the boundary - vapour region three-phase solid were experimentally determined under pressure on system methane + decane heavy fraction using a full visibility sapphire cell. Measurements performed different mixtures made up of 90% binary mixture (with molar about 50 %) 10 % composed various distributions normal paraffins centered around C 22 . The liquid-solid transition was investigated to 45 MPa fluid studied in temperature domain from 293 K 423 K.
