This work investigates the effect of different conditions of PFO thermal cracking from two PFO samples on liquid, solid and gas product yield and asphaltene removal efficiency in a new designed experimental setup. No need to use a catalyst, simple operating system and experiment conditions, the ability to use water as a cheap carrier gas and high asphaltene extraction efficiency without the use...
Surface enhanced Raman spectroscopy using a gold substrate and excitation at 514 nm can detect sub parts per million quantities of asphaltene and thereby petroleum. This simple format and sensitivity make it transformative for applications including sample triage, flow assurance, environmental protection and analysis of unique one of a kind materials.
This work presents a systematic study of asphaltene pre-aggregation phenomena in the absence and presence ionic liquids (ILs) from family 1-alkyl-3-methylimidazolium by molecular dynamics simulations. The effects alkyl chain length cation (studying ILs with chains between C4 C10) dimension anion (testing chloride bromide) on aggregation behavior asphaltenes have been studied. To correlate resul...
Semi-empirical fouling models have proven more effective in predicting the behavior of crude oils heat exchangers. These aided refineries optimizing operating conditions to minimize or eliminate preheat Despite their complexity, continue improve approximating real by taking into account previously neglected aspects. This paper summarizes these findings from various studies along with highlighti...
Abstract Bitumen contains approximately 5 wt% sulfur so it must be removed before being used as fuel. Herein, we performed oxidative desulfurization of bitumen at room temperature using n-pentane and ultrasound to reduce viscosity mix the bitumen-dissolved aqueous reaction solution physically. The states in ratio were investigated confirm process. Additionally, developed a novel method for sepa...
state, heat/mass transfer between gas and liquid, fluid hydrodynamics in the wellbore depend highly on temperature pressure conditions, multiphase flow behaviors deep-stratum deep-water wellbores become much more complicated. Different from conventional oil exploitation, production of deep stratum regions involves multiple complex physical phenomena, such as phase transition (gas-liquid-solid-s...
