To quantitatively analyze the effects of coupling port water injection (PWI) and exhaust gas recirculation (EGR) on the spray water evolution, combustion and emissions for the stoichiometric natural gas engines, five cases were tested on the…
Novel cement based mortars containing bottom ash (BA) and phase change material (PCM) as thermal energy storing material were developed for thermal controlling of buildings. Form-stable BA/Capric-Stearic (C-S) acid eutectic mixture composite was…
In this experimental study, a flat plate solar collector was constructed and examined for absorbing and transferring heat from soil to fluid. The light source was an infrared lamp with average illumination intensity of 3150 lux. For the first time,…
Dehydration of natural gas by absorption using triethylene glycol (TEG) is a common industrial offshore procedure to ensure the compliance with the required water dew point specifications for midstream transportation. Two thermodynamic models, the…
A novel bio-based polyurethane (BPU) hydroponic foam was developed by substituting up to 100% of petroleum-derived polyol with bio-polyol derived from cost-effective organosolv fractionation of Miscanthus in an acetic acid-water (9/1, v/v) mixed…
Renewable energy, such as geothermal, is very effective in reducing the effects of greenhouse gas emissions. Therefore, a geothermal-based multi-generation system can produce commodities for power, hydrogen, liquefied natural gas, cold energy…
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…
Studies on gas hydrate phase equilibrium conditions are reported widely in the literature. However, the data available for natural gas hydrates (NGHs) in real marine conditions are limited. In this study, NGH dissociation conditions in bulk brine and…
Large-scale gas accumulation areas in large oil-gas basins in central and Western China have multiple special accumulation mechanisms and different accumulation effects. Based on the geological theory and method of natural gas reservoir formation,…
Dibenzofurans, oxygen-containing heterocyclic aromatics, are ubiquitous in crude oils. Their geochemical implications in petroleum geochemistry have been studied in numerous previous publications. Here, we present the distribution of dibenzofuran and…
Offshore processing of natural gas with 44%mol carbon dioxide at remote deep-water oil-and-gas fields is invariably characterized by low-efficiency power generation via gas-fired turbines releasing hot flue-gas and entailing high degradation of…
Supersonic separators offer a cleaner offshore processing of natural gas with carbon dioxide content from deep-water oil-gas fields. Conventional offshore gas processing comprises water dew-point adjustment via glycol-absorption, hydrocarbon…
Offshore processing of natural gas with 44%mol carbon dioxide at remote deep-water oil-and-gas fields is invariably characterized by low-efficiency power generation via gas-fired turbines releasing hot flue-gas and entailing high degradation of…
