Abstract:

LPG gas is one of the substances with a high potential for environmental harm that is now widely employed in industry and other applications. In this study, the ALOHA model was utilized with varied wind speeds to assess the impact of releasing LPG into the environment, which causes a negative effect on human health. The purpose of this study is to show the toxic and flammable area of the affected area from the released LPG vapor cloud. The red zone (AEGL-3) of the toxic and flammable vapor cloud from the released gas remains constant with increasing ambient wind velocity for each LPG property

Abstract:

This work considers the possibility of separating the natural gas from the Orenburg field using gas hydrate crystallization technology to purify methane from impurities. The effect of the mixture composition, process temperature, and pressure on the separation efficiencyof the gas mixture CH4 - C2H6 - C3H8 - i-C4H10 - н-C4H10 - C5H12 - N2 - H2S - CO2 was mathematically modeled. Efficiency was determined based on gas hydrate distribution coefficients. It was shown that the CH4 gas hydrate distribution coefficient variedinsignificantly with the field operation time and amounted to less than 1. T

There is also a stabilization process by alkanes of CeH8+• ion species, but its importance is lower than the above transfer processes.

The laminar burning velocity is a significative parameter that characterises the combustion process of any fuel–air mixture.

En ambientes donde podría presentarse fuga de gases como el monóxido de carbono y butano, puede llegar a convertirse en un importante riesgo para cualquier humano. Por esta razón se considera necesario el estudio de la detección de estos gases para alertar posible riesgo de asfixias, explosiones e incendios. Se plantea como objetivo desarrollar un sistema electrónico de control automatizado para la detección de niveles peligrosos de concentración de gas butano (C4H10) y monóxido de carbono (CO), en ambientes propensos a la presencia de estos gases, que podría prevenir algún futuro accidente.

Abstract:

Ion–molecule reactions of C2H3Cl+ with propane or n-butane have been studied using a photoionization mass spectrometer over the pressure range 0.01–1 Torr. The principal reasons for disappearance of the C2H3Cl+ ion in propane and n-butane are the H−, H2− transfer processes and charge transfer in the case of n-C4H10. The ions CnH2n+1+ and CnH2n+ formed in these transfers react preferentially with neutral vinyl chloride in condensation reactions with elimination of HCl or Cl•. Keywords: ion–molecule reactions, mass spectrometry, vinyl chloride, propane, n-butane. [Journal translation]

Abstract:

The viscosity of some simple fluids in the wide density and temperature ranges have been calculated by the modified Enskog theory (MET) and with the help of Kaplun equations. The thermal pressure, second virial coefficient and internal energy are calculated from the modified SAFT-BACK EOS. The proposed scheme was further examined for the prediction of the viscosity of some dense fluids, including Ar, N2, O2, CO2, CH4, C2H6, C3H8 and C4H10. A comparison of the calculated and experimental values of the viscosity yields an overall average deviation of 2.16%.

Abstract:

A novel composite hollow fiber membrane has been developed for the separation of C2+ hydrocarbons from their mixture with methane. A high-performance porous polysulfone hollow fiber support was fabricated. Polydecylmethylsiloxane (PDecMS) and polydimethylsiloxane (PDMS) were used as a thin selective layer. Comparison of the results of separation of binary mixture of CH4 and C4H10 using PDecMS/PSF and PDMS/PSF membranes showed that for the PDecMS/PSF module the specific retentate flux and n-butane concentration in the permeate are 1.7 times higher and energy consumption is 9 times lower.

Abstract:

Raman spectroscopy is a promising method for the analysis of natural gas. It is necessary to account for the broadening effects on spectral lines to improve measurement accuracy. In this study, the broadening coefficients for methane lines in the region of the ν2 band perturbed by propane, n-butane, and isobutane at room temperature were measured. We estimated the measurement errors of the concentration of oxygen and carbon dioxide in the case of neglecting the broadening effects on the methane spectrum by the pressure of C2–C6 alkanes. The obtained data are suited for the correct simulation o

Abstract:

The development of membrane materials with high transport and separation properties for the removal of higher hydrocarbons from gas mixtures is an important and complex task. This work examines the effect of a cross-linking agent on the structure and transport properties of polydecylmethylsiloxane (C10), a material characterized by high selectivity towards C3+ hydrocarbons. C10 was cross-linked with various diene hydrocarbons, such as 1,7-octadiene (C10-OD), 1,9-decadiene (C10-DD), 1,11-dodecadiene (C10-DdD), and vinyl-terminated polysiloxanes, of different molecular weights: 500 g/mol (C10-Si

Abstract:

During reservoir engineering analysis, the assessment of the possibility of asphaltene precipitation and corresponding heavy oil recovery with economic losses is carried out before any thermal operation. Since, asphaltene precipitation reduces oil production, both by plugging the pipeline network and by decreasing the effective permeability in the reservoir. In this study, to analyze this phenomenon, three steam injection experiments; only-steam, steam-CO2, and steam-n-C4H10 at 1:1,29 volumetric ratios were carried out in limestone cores saturated with a 12,4 °API heavy crude oil.
