Triboelectric nanogenerators(TENGs)have potential to achieve energy harvesting and condition monitoring of oils,the“lifeblood”of industry.However,oil absorption on the solid surfaces is a great challenge for oil-solid TENG(O-TENG).Here,oleophobic/superamphiphobic O-TENGs are achieved via engineering of solid surface wetting properties.The designed O-TENG can generate an excellent electricity(with a charge density of 9.1μC m^(−2) and a power density of 1.23 mW m^(−2)),which is an order of magnitude higher than other O-TENGs made from polytetrafluoroethylene and polyimide.It also has a significant durability(30,000 cycles)and can power a digital thermometer for self-powered sensor applications.Further,a superhigh-sensitivity O-TENG monitoring system is successfully developed for real-time detecting particle/water contaminants in oils.The O-TENG can detect particle contaminants at least down to 0.01 wt%and water contaminants down to 100 ppm,which are much better than previous online monitoring methods(particle>0.1 wt%;water>1000 ppm).More interesting,the developed O-TENG can also distinguish water from other contaminants,which means the developed O-TENG has a highly water-selective performance.This work provides an ideal strategy for enhancing the output and durability of TENGs for oil-solid contact and opens new intelligent pathways for oil-solid energy harvesting and oil condition monitoring.

Chinese Journal of Chemical Engineering 2023年第4期56卷 266-272页

It is known that injection of carbon dioxide into the petroleum reservoir(CO_(2) flooding) is one of the effective methods for enhanced oil recovery. CO_(2) flooding may be complicated by formation of CO_(2) hydrate plugs. It makes topical investigation of CO_(2) hydrate formation in the system gaseous CO_(2)-oil-water. In this work, the growth rates of carbon dioxide hydrate films at the water-oil as well as the water-gas interface are studied in the pressure range of 2.30-3.04 MPa and at temperatures between -5.4 and 5.0℃. It is found that the growth rate for the water-oil interface is 3.5 times lower than that for the water-gas interface with carbon dioxide. It is hypothesised that the observed decrease in the growth rate is related to the mechanical resistance of the oil components adsorbed on the interface to the growth of the hydrate film. The growth rate of the film has been shown to depend on the experimental procedure,most likely due to the different initial concentrations of carbon dioxide in the aqueous solutions.

China is the largest producer and consumer of HFC-134a(1,1,1,2-tetrafluoroethane)in the world.Coal-based route is mainly adopted to produce HFC-134a,which suffers from large waste and CO_(2) emissions.Natural gas is a low-carbon and clean energy resource,and no research has been found on the environment and economy of producing HFC-134a from natural gas.In this study,CML 2001 method was used to carry out the life cycle assessment of natural gas(partial oxidation)-based and natural gas(plasma cracking)-based routes(abbreviated as gas(O)-based and gas(P)-based routes,respectively),and their environmental performances were compared with coal-based and oil-based routes.Meanwhile,considering that China is vigorously promoting the transformation of energy structure,and the application of electric heating equipment to replace fossil-based heating equipment in industrial field,which has a great impact on the environmental performance of the production processes,the authors conducted a scenario analysis.The results showed that the gas(O)-based route had the most favourable environmental benefits.However,the gas(P)-based route had the highest potential for reducing environmental burdens,and its environmental benefit was the most favourable in scenario 2050.Additionally,the economic performance of the gas(P)-based route was significantly better than that of gas(O)-based and coal-based routes.

The technological revolution has spawned a new generation of industrial systems, but it has also put forward higher requirements for safety management accuracy, timeliness, and systematicness. Risk assessment needs to evolve to address the existing and future challenges by considering the new demands and advancements in safety management. The study aims to propose a systematic and comprehensive risk assessment method to meet the needs of process system safety management. The methodology first incorporates possibility, severity, and dynamicity (PSD) to structure the "51X" evaluation indicator system, including the inherent, management, and disturbance risk factors. Subsequently, the four-tier (risk point-unit-enterprise-region) risk assessment (RA) mathematical model has been established to consider supervision needs. And in conclusion, the application of the PSD-RA method in ammonia refrigeration workshop cases and safety risk monitoring systems is presented to illustrate the feasibility and effectiveness of the proposed PSD-RA method in safety management. The findings show that the PSD-RA method can be well integrated with the needs of safety work informatization, which is also helpful for implementing the enterprise's safety work responsibility and the government's safety supervision responsibility.

The phase behavior of gas condensate in reservoir formations differs from that in pressure-volume -temperature (PVT) cells because it is influenced by porous media in the reservoir formations. Sandstone was used as a sample to investigate the influence of porous media on the phase behavior of the gas condensate. The pore structure was first analyzed using computed tomography (CT) scanning, digital core technology, and a pore network model. The sandstone core sample was then saturated with gas condensate for the pressure depletion experiment. After each pressure-depletion state was stable, realtime CT scanning was performed on the sample. The scanning results of the sample were reconstructed into three-dimensional grayscale images, and the gas condensate and condensate liquid were segmented based on gray value discrepancy to dynamically characterize the phase behavior of the gas condensate in porous media. Pore network models of the condensate liquid ganglia under different pressures were built to calculate the characteristic parameters, including the average radius, coordination number, and tortuosity, and to analyze the changing mechanism caused by the phase behavior change of the gas condensate. Four types of condensate liquid (clustered, branched, membranous, and droplet ganglia) were then classified by shape factor and Euler number to investigate their morphological changes dynamically and elaborately. The results show that the dew point pressure of the gas condensate in porous media is 12.7 MPa, which is 0.7 MPa higher than 12.0 MPa in PVT cells. The average radius, volume, and coordination number of the condensate liquid ganglia increased when the system pressure was between the dew point pressure (12.7 MPa) and the pressure for the maximum liquid dropout, Pmax (10.0 MPa), and decreased when it was below Pmax. The volume proportion of clustered ganglia was the highest, followed by branched, membranous, and droplet ganglia. This study provides crucial experimental evidence for the phase behavior changing pro

The coupling control of biological precursors and environmental factors on 0-carotane enrichment in alkaline lacustrine source rocks: A case study from the Fengcheng formation in the western Junggar Basin, NW China

引用

PETROLEUM SCIENCE 2024年第2期21卷 836-854页

The organic-rich mudstones and dolostones of the Permian Fengcheng Formation (Fm.) are typically alkaline lacustrine source rocks, which are typified by impressively abundant 0-carotane. Abundant 0carotane has been well acknowledged as an effective indicator of biological sources or depositional environments. However, the specific biological sources of 0-carotane and the coupling control of biological sources and environmental factors on the enrichment of 0-carotane in the Fengcheng Fm. remains obscure. Based on a comprehensive investigation of the bulk, molecular geochemistry, and organic petrology of sedimentary rocks and the biochemistry of phytoplankton in modern alkaline lakes, we proposed a new understanding of the biological precursors of 0-carotane and elucidated the enrichment mechanism of 0-carotane in the Fengcheng Fm. The results show that the biological precursors crucially control the enrichment of 0-carotane in the Fengcheng Fm. The haloalkaliphilic cyanobacteria are the primary biological sources of 0-carotane, which is suggested by a good positive correlation between the 2-methylhopane index, 7- & thorn; 8- methyl heptadecanes/Cmax, C29%, and 0-carotane/Cmax in sedimentary rocks and the predominance of cyanobacteria with abundant 0-carotene in modern alkaline lakes. The enrichment of 0-carotane requires the reducing condition, and the paleoredox state that affects the enrichment of 0-carotane appears to have a threshold. The paleoclimate conditions do not considerably impact the enrichment of 0-carotane, but they have some influence on the water's paleosalinity by affecting evaporation and precipitation. While it does not directly affect the enrichment of 0-carotane in the Fengcheng Fm., paleosalinity does have an impact on the cyanobacterial precursor supply and the preservation conditions.

Fault movement during earthquakes is a geotechnical phenomenon threatening buried pipelines and with the potential to cause severe damage to critical infrastructures. Therefore, effective prediction of pipe displacement is crucial for preventive management strategies. This study aims to develop a fast, hybrid model for predicting vertical displacement of pipe networks when they experience faulting. In this study, the complex behavior of soil and a buried pipeline system subjected to a normal fault is analyzed by using an artificial neural network (ANN) to generate predictions the behavior of the soil when different parameters of it are changed. For this purpose, a finite element model is developed for a pipeline subjected to normal fault displacements. The data bank used for training the ANN includes all the critical soil parameters (cohesion, internal friction angle, Young's modulus, and faulting). Furthermore, a mathematical formula is presented, based on biases and weights of the ANN model. Experimental results show that the maximum error of the presented formula is 2.03%, which makes the proposed technique efficiently predict the vertical displacement of buried pipelines and hence, helps to optimize the upcoming pipeline projects.

As a potential substitute for fatty acids,common low-cost oils could be used to produce acetyl-CoA derivatives,which meet the needs of low-cost industrial production.However,oils are hydrophobic macromolecules and cannot be directly transported into cells.In this study,caveolin was expressed in Saccharomyces cerevisiae to absorb exogenous oils.The expression of caveolin fused with green fluorescent protein showed that caveolin mediated the formation of microvesicles in S.cerevisiae and the addition of 5,6-carboxyfluorescein showed that caveolae had the ability to transport exogenous substances into cells.The intracellular and extracellular triacylglycerol levels were then detected after the addition of soybean oil pre-stained with Nile Red,which proved that caveolae had the ability to absorb the exogenous oils.Lastly,caveolin for oils absorption and lipase from Bacillus pumilus for oil hydrolysis were co-expressed in the naringenin-producing Saccharomyces cerevisiae strain,resulting in naringenin production increasing from 222 mg/g DCW(dry cell weight)(231 mg/L)to 269 mg/g DCW(241 mg/L).These results suggested that the caveolin-mediated transporter independent oil transport system would provide a promising strategy for the transport of hydrophobic substrates.

Thermo -responsive nanocomposites have recently emerged as potential nanoplugging agents for shale stabilization in high -temperature water -based drilling fluids (WBDFs). However, their inhibitory properties have not been very effective in high -temperature drilling operations. Thermo -responsive Janus nanocomposites are expected to strongly interact with clay particles from the inward hemisphere of nanomaterials, which drive the establishment of a tighter hydrophobic membrane over the shale surface at the outward hemisphere under geothermal conditions for shale stabilization. This work combines the synergistic bene fits of thermo-responsive and zwitterionic nanomaterials to synchronously enhance the chemical inhibitions and plugging performances in shale under harsh conditions. A novel thermoresponsive Janus nanosilica (TRJS) exhibiting zwitterionic character was synthesized, characterized, and assessed as shale stabilizer for WBDFs at high temperatures. Compared to pristine nanosilica (SiNP) and symmetrical thermo-responsive nanosilica (TRS), TRJS exhibited anti-polyelectrolyte behaviour, in which electrolyte ions screened the electrostatic attraction between the charged particles, potentially stabilizing nanomaterial in hostile shaly environments (i.e., up to saturated brine or API brine). Macroscopically, TRJS exhibited higher chemical inhibition than SiNP and TRS in brine, prompting a better capability to control pressure penetration. TRJS adsorbed onto the clay surface via chemisorption and hydrogen bonding, and the interactions became substantial in brine, according to the results of electrophoretic mobility, surface wettability, and X-ray diffraction. Thus, contributing to the firm trapping of TRJS into the nanopore structure of the shale, triggering the formation of a tight hydrophobic membrane over the shale surface from the outward hemisphere. The addition of TRJS into WBDF had no deleterious effect on fluid properties after hot -treatment at 190 degrees C, implying that TRJS could find potential use
