Shale energy extraction activities in residential areas have the potential to adversely affect human health. The oil and gas sector is the largest industrial source of volatile organic compounds, which are dangerous because they include hazardous air…
We used a reactive transport model to investigate the cycling of geogenic arsenic (As) in a petroleum-contaminated aquifer. We simulated As mobilization and sequestration using surface complexation reactions with Fe(OH)3 during petroleum…
Fast pyrolysis is a controlled process of biomass thermal decomposition designed to yield high volumes of liquid bio-oil, which can subsequently be upgraded into high energy density transportation biofuels such as green gasoline, green jet fuel and…
Petroleum refinery has been developed for production of transportation fuel with light alkenes and benzene, toluene, ethylbenzene, and xylenes (abbreviated BTEX), but global market demands are shifting to chemicals produced from light alkenes and…
Hydrothermal diamond-anvil cell and Raman spectrograph were used to measure the hydrogen isotope fractionation factor between benzene and heavy water at high P-T condition. The isotope fractionation factor is determined when the isotope fractionation…
Abstract: The effect of ultrasound and kind of petroleum resins on the composition of the dispersion medium (raffinates) recovered from a 6 wt % solution of petroleum wax in decane as a result of precipitate formation was studied. Irrespective of the…
The primary migration of petroleum has been recently described in detail for a thermally mature core of the Barnett Shale with almost nonvariant organofacies and maturity. Here, we use samples from the same well to provide new insights into the…
The removal of CO2 from natural gas will enhance its energy content, decrease the volume to be transported and if coupled with storage technology- it will also contribute to the control of CO2 emissions. Amine-based chemical absorption is the most…
The present study reports, high-performance polymer absorbents for crude oil and organic solvents based on 3D cross-linked polystyrene-polymethyl methacrylate/divinyl benzene (PS-PMMA/DVB). The preparation of the 3D cross-linked polymer absorbents…
The presence of benzene and similar aromatic compounds in civil environments is due to anthropic actions but also to natural sources. Natural gas consists of a gas mixture where benzene and related compounds are usually presents. Thus, the detection…
Fractionation of bio-oil is in favor of upgrading bio-oil to transport fuel or chemicals. The microalgae Dunaliella tertiolecta was hydrothermally liquefied to form a bio-oil, which was split into two layers during cooling: the lower layer contained…
Nowadays, there is a significant increase in the share of unconventional oil reserves such as heavy and extra-heavy oils as well as natural bitumen among the total balance of extracted petroleum feedstock. In this regard, one of the most important…
Direct measurements of impurity freeze-out conditions in real time are needed to improve the reliability of liquefied natural gas (LNG) production. Benzene and carbon dioxide are two impurities in the feed mixtures processed by LNG plants that can…
Toxic vapor emissions (TVEs) from crude oil and condensate storage tanks contain volatile organic compounds which are precursors for ground level ozone formation. Vapor recovery units have been proposed for the control of TVEs but come with high…
Direct measurements of impurity freeze-out conditions in real time are needed to improve the reliability of liquefied natural gas (LNG) production. Benzene and carbon dioxide are two impurities in the feed mixtures processed by LNG plants that can…
The Permian Basin in West Texas and Eastern New Mexico has a long and phenomenal history that has continued for most of a century. While the East Texas field experience was the event that brought Texas onto the world stage as a major source of crude…
Since the early 1960s, a series of potentially mutagenic and carcinogenic xenobiotics have been identified in foods, resulting from chemical changes induced by processing. The toxic effects have been extensively studied and demonstrated in…
While most clinicians recognize adult therapy-related leukemias following cytotoxic chemotherapy and radiation, environmental regulatory agencies evaluate exposure to “safe levels” of leukemogenic compounds. Benzene represents the most notorious…
Objective The control room A and B employees are a high risk of benzene exposure, because they work close to the waste pit which is a source of benzene. This study is to analyze the magnitude of the health risk of benzene exposure to all employees.…
Several treatment methods, applying physical, chemical and biological processes were developed in the past decades. Physicochemical measures are capable of removing most of the contaminants, but the main disadvantages of these methods lie in the…
