Abstract

The solubility of sulfur in toluene, o-xylene, m-xylene and p-xylene was investigated at temperatures ranging from 303.15 K to 363.15 K. This study was required for the design of the regeneration section of the novel Vitrisol ® desulfurization process. It was determined that, for experimental conditions studied, o-xylene exhibited the highest sulfur solubility and toluene the lowest sulfur solubility from the investigated aromatic hydrocarbons. The sulfur solubility data reported in this study were in good agreement with sulfur solubility data in toluene, m-xylene and p-xylene published in open literature. Sulfur solubility data in o-xylene was not published in open literature. The temperature dependences of the solubility of sulfur in toluene, o-xylene, m-xylene and p-xylene were determined from solubility equilibria. The enthalpies of dissolution Δ Ho of sulfur in toluene, o-xylene, m-xylene and p-xylene were determined to be 27.93 kJ/mol, 27.95 kJ/mol, 26.98 kJ/mol and 27.70 kJ/mol respectively.

Abstract

This work reports high-quality isothermal vapor–liquid equilibrium data for ethane + ethanethiol (or ethyl mercaptan) at 303 K, 323 K and 343 K and pressures up to 6.25 MPa. A sapphire-tube equilibrium cell with an online micro sampler and GC-TCD are employed to measure equilibrium phase concentrations at specific temperatures and pressures. Peng Robinson equation of state with classical alpha function is found adequate for data treatment and thermodynamic modelling.

Abstract

Radial fractures are created in unconventional gas and oil reservoirs in modern well stimulation operations such as Hydraulic Re-Fracturing (HRF), Explosive Fracturing (EF) and High Energy Gas Fracturing (HEGF). This paper presents a mathematical model to describe fluid flow from reservoir through radial fractures to wellbore. The model can be applied to analyzing angles between radial fractures. Field case studies were carried out with the model using pressure transient data from three typical HRF wells in a lower-permeability reservoir. The studies show a good correlation between observed well performance and model-interpreted fracture angle. The well with the highest productivity improvement by the HRF corresponds to the interpreted perpendicular fractures, while the well with the lowest productivity improvement corresponds to the interpreted conditions where the second fracture is much shorter than the first one or where there created two merged/parallel fractures. Result of the case studies of a tight sand reservoir supports the analytical model.

About this journal

Journal of Natural Gas Engineering (JNGE), is a fully peer-reviewed, open access, electronic journal publishing original research covering the newest and most innovative engineering, scientific, and technological advances in natural gas engineering. Our aim is to publish your work as efficiently and effectively as possible so the world is aware of it. Our standard policy requires each paper to be reviewed by at least two referees and the peer-review process is single-blind.

The Journal of Natural Gas Engineering is publishing original research on the engineering, scientific, and technological advances covering all aspects of natural gas engineering: production, transportation, and processing. In addition, JNGE will include auxiliary subjects such as thermodynamics, physical properties, phase equilibrium, etc. related to the natural gas industry. The intention is to include modelling and theoretical studies, experimental work, and field data.

Natural gas is an extremely important source of fuel and power, and its global importance is growing. Thus, JNGE seeks to include research by engineers and scientists from every country and region in the world where natural gas is relevant, and thereby contributing both practical and theoretical material to the global body of scientific literature in this area. Papers are invited on any individual topic in natural gas engineering or on those which are interdisciplinary.
