Oily wastewater can have a great impact on human health and the surrounding environment. The current methods for treating oily mainly included physical methods, chemical membrane separation technology other mechanical methods. Compared with had advantages of high efficiency, low cost, simple operation, energy saving environmental protection in separating general oil-water emulsions, thus having wide application prospect. In order to understand materials separation, such as improving...
Poly(ethylene imine) (PEI) has abundant amino groups in a macromolecular chain and can be used as graft source for metal nanocomposites, which shows excellent ability to form stable complexes with heavy ions. In this work, simple convenient method was make PEI into hydrogel 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide-N-hydroxysuccinimide subsequently coprecipitate silver nitrate solution or palladium chloride metal-loaded composite hydrogels. addition, the characterizations of hydrogels...
The construction of low-cost, high-performance electrocatalysts instead platinum catalysts is critical to solving the energy crisis. Here, using simple electrospinning and hydrothermal methods, new MoS2 nanosheets on SrTiO3 nanofibers (NFs) 2D SrTiO3@MoS2 heterostructure NFs are synthesized. In addition, compared with bare nanosheets. Importantly, prepared shows better hydrogen-evolution reaction performance than other MoS2-based an overpotential 165 mV at 10 mA cm-2, a Tafel slope 81.41...
Hydrates are mainly stored in the pores of sedimentary layer, so their formation and storage characteristics particularly important for exploitation utilization hydrates. Meanwhile, order to study rapid methods hydrate, 300 ppm sodium dodecyl sulfate (SDS) solutions mixed with alumina silica particles, respectively, were used investigating hydrate porous media under conditions 275.15 K 7 MPa. The particle sizes 2, 4, 6 mm. experimental results indicated smaller size could shorten induction...
In order to visualize multiphase fluid seepage in porous reservoir media due gravitational differentiation, a series of innovative experimental devices for individual or composite repulsion were fabricated study and analyze the effects mode, glass bead diameter, inclination angle, settling time, crude oil viscosity on differentiation oil, gas, water. The results show that compared with actual production process reservoir, which requires long time transport aggregation fluids under action...
In this work, the influence of dissolution methane (CH4) gas on wax crystal waxy crude oil and effect rheology by dissolved CH4 were studied comprehensively. A self-deign high-pressure micro visualization device was developed to analyze crystals before after dissolution. The from Shengli Nanyang tested under various pressures. Results showed that viscosity, maximum shear stress equilibrium decreased with increasing pressure CH4. Due supersaturation gas, initially increased change in can be a...
The crystallization behavior of Shengli waxy crude oil from the sol state to gel was studied by microscopic observation and DSC curve. study shows that as cooling rate decreases, number wax grains becomes smaller, area is larger morphology crystals more irregular. Moreover, under different rates, were homogeneous transient nucleation, but growth mode different. When between 1–4 °C/min, Crystallization Peak 1 crystal grows according mixed one-dimensional rod two-dimensional discoid crystal;...
Natural gas hydrate (NGH), as a clean energy with great development potential, has been limited by the lack of efficient and safe exploitation methods for long time. The CO2 displacement method proposed in recent years not made substantial progress because its poor permeability low efficiency. NH3 replacement is this paper strong permeability. We performed orthogonal molecular dynamics simulation CH4 at different temperatures (245 K, 255 265 K) pressures (3 MPa, 5 10 MPa). It shown that:(1)...
Calculation process of some reservoir engineering problems involves several passes full-order numerical simulations, and this makes it a time-consuming process. In study, fast method based on proper orthogonal decomposition (POD) was developed to predict flow heat transfer oil water in reservoir. The reduced order model for the hot water-drive generated. Then, POD used extract set basis functions from series “snapshots” obtained by finite difference (FDM), these most efficiently represent...
To address the complexity of unsteady shear flow in initial start-up stage rheometers, a model considering torque losses motors and fixtures was developed based on true balance relationship at rotor boundary rheometer constitutive equation viscoelastic rheological model. The fluid transient established, real wall stress expression obtained. reliability verified by comparing result from analytical with numerical calculation. impact geometric dimensions test system material characteristics...
In this paper, with the application of a MARS 60 high-pressure rheometer, experimental tests are conducted on Shengli crude oil to test its gel point, viscosity and thixotropy under different static pressures. Consequently, effect pressure rheological parameters waxy is revealed. It proven that increase in pressure, point increases linearly, also gradually increases. The power law equation employed describe relationship between apparent shear rate With consistency coefficient (K) index (n)...
