On-site wastewater treatment systems are gaining popularity in areas where centralized wastewater treatment is not available. In the current case study a domestic activated sludge system was investigated, where treated effluent was stored in a…
An environmentally-benign supercritical fluid route is developed to demulsify and treat highly intractable petroleum emulsions containing hazardous acidic compounds, heavy fractions, heteroatoms, and metallic impurities without using external…
Mesocarbon microbeads (MCMBs) are a valuable carbon material, and the production of this material highly depends on the reaction conditions and feedstock properties. In the present study, supercritical fluid extraction fractionation (SFEF) technology…
Low-pressure membrane technology (ultrafiltration and microfiltration) has been applied to two key effluents generated by the petroleum industry: produced water (PW) from oil exploration, a significant proportion being generated offshore, and onshore…
Scope: This part of ISO 20765 specifies a method to calculate volumetric and caloric properties of natural gases, manufactured fuel gases, and similar mixtures, at conditions where the mixture may be in either the homogeneous (single-phase) gas…
Supercritical fractionation is a unit operation which allows separation and purification of liquid mixtures and is of particular interest for low-volatility and thermosensitive mixtures. This process is an environmentally friendly alternative to…
Some deep-water offshore fields produce oil with high gas/oil ratios and ultra-high %CO2 (>60%mol) with the onus of processing low-grade gas simultaneously handling huge CO2 dispatch goals. Thus, processing solutions are needed to make feasible such…
Supercritical fluids offer considerable advantages for the isolation of natural products. Supercritical fluids can be used as antisolvents to precipitate selectively target compounds from a mixture and to remove impurities by the Supercritical…
In this study a novel sustainable method based on supercritical fluid extraction (SFE) method was developed for simultaneous extraction and fractionation of petroleum biomarkers. We herein proposed a two-step supercritical fluid extraction method for…
A combination of multi-dimensional supercritical fluid chromatography and field ionization time-of-flight mass spectrometry (SFC FI-TOF MS) is developed for the detailed analysis of olefins and other hydrocarbon types in total petroleum liquid…
