Phase behavior of hydrogen–light-hydrocarbon systems

phase behavior study of near critical hydrocarbon fluids of one iranian reservoir

the conventional phase behavior study of petroleum reservoir fluids are valid when the reservoir temperature is far enough from the critical condition in which the material balance equation can be applied correctly. when the temperature of the reservoir is in the vicinity of the critical temperature the classical methods can’t determine the phase behavior of the mixture due to rapid phase chang...

Phase Behavior of Sulfonated Polystyrene Systems

INTRODUCTION Polymer blends are of great interest because they provide an economical route to design and produce novel materials that meet the challenging requirements for industrial applications. Recently, a variety of experimental and theoretical work has been conducted as a means for producing materials with improved properties compared to those of its constituents. Some of the findings sugg...

High Temperature Behavior of Dual Phase Steels

Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...

Phase Behavior Cur Of Reservoir Fluid

Phase behavior, rheological property, and transmutation of vesicles in fluorocarbon and hydrocarbon surfactant mixtures.

We present a detailed study of a salt-free cationic/anionic (catanionic) surfactant system where a strongly alkaline cationic surfactant (tetradecyltrimethylammonium hydroxide, TTAOH) was mixed with a single-chain fluorocarbon acid (nonadecafluorodecanoic acid, NFDA) and a hyperbranched hydrocarbon acid [di-(2-ethylhexyl)phosphoric acid, DEHPA] in water. Typically the concentration of TTAOH is ...
