Characteristics of elemental fluorine and carbon-fluorine bonds were analyzed. The barrier and oil-resistance properties of direct fluorination of HDOE were unveiled from molecule structure. The HDPE surface fluorination results in the increase of surface energy, cross link to some extent and shrinkage of polymer free volume.The application of direct fluorination of HDPE in oil in oil & gas storage and transportation fields were reviewed, including oil and gas pipe,plastic petrol-tanks and HDPE impermeable membrane applied in oil tank foundation. After direct fluorination processing, the anti-corrosion and the permeability to hydrocarbons of HDPE pipes are strengthened. With the development of technology, it will be the trend that the multi-layer fuel tanks replace the single layer fuel tanks. The HDPE is applied as the outermost layer of multi-layer structure to ensure the processing property and the impact resistance in low temperature.

A novel protective structure, based on shrimp chela structure and the shape of odontodactylus scyllarus, has been shown to improve impact resistance and energy absorption. A finite element model of NiTi alloy with shape memory was constructed based on the basic principles of structural bionics. The protective structure utilizes NiTi alloy as the matrix, a material with many advantages including excellent compression energy absorption, reusability after unloading, and long life. The mechanical properties of the single-layer model were obtained by static crushing experiments and numerical simulations. Building upon the idea of the monolayer bionic structure design, a two-layer structure is also conceived. Both single-layer and double-layer structures have excellent compression energy absorption and self-recovery capabilities. Compared with the single-layer structure, the double-layer structure showed larger compression deformation and exhibited better energy absorption capacity. These results have important academic and practical significance for improving the impact resistance of protective armor. Our study makes it possible to repair automatic rebounds under the action of pressure load and improves the endurance and material utilization rate of other protective structures.

The paper presents the data on the situation of the oil and gas complex of the Saratov region. It is shown that the Saratov region is a promising region for hydrocarbon production and one of the leaders in the Volga Federal district, since 85 % of the territory is occupied by oil and gas-promising lands. The structure of the oil and gas complex and the dynamics of production of hydrocarbons in the region are presented in the article. The paper describes the indicators of the oil and gas complex, background accident risks that determine environmental pollution. The results of monitoring the pollution of the territory of the largest in Europe Stepnovsky gas storage facility, created on the basis of the Stepnovsky oil and gas processing enterprise, which operated from 1953 to 1973, are given. It is proved that during the production and storage of hydrocarbons at this enterprise, there was a strong pollution of the soil with oil and petroleum products, so their content reaches 1527 mg/kg of soil in the upper half-meter layer, and 2060 mg/kg of soil in the second half-meter. The content of plumbum and copper in the soil is 3.3 and 2.3 times higher above the background values for dark chestnut soils. The accumulation of a significant amount of unsaturated hydrocarbons (C1-C10) in the subsurface air from 25.97 mg/m3 to 38.17 mg/m3 is proved. It is shown that the extraction and storage of hydrocarbons at the Stepnovsky enterprise did not lead to a deterioration of the sanitary and microbiological condition of the studied soil.


The impact of corrosion within the refining industry ends up in the failure of components. This failure leads to closing down the plant to scrub the corroded components. Additionally, corrosion normally causes serious environmental issues, namely spills and releases. A vital resource for all those that are concerned within the corrosion management of oil and gas infrastructure, corrosion management within the oil and gas industry provides engineers and designers with the tools and strategies to plan and implement comprehensive corrosion-management programs for oil and gas infrastructures. Control of corrosion is important for continuous production and evading the well control losses. Materials to be used in down hole have to meet certain characteristics to avoid corrosion and provide additional mechanical strenght. It is potential to determine a logical series of steps for material choice, incorporating analysis of the surroundings, corrosion rate calculations, and final material choice based on established limits. Several developments have taken place in refinement the calculation of CO2 corrosion rates. Moreover, the definition of bitter examination has been reviewed and a way wider evaluation of the relevance of varied established and new materials for various service conditions has been created.

The petroleum (oil, gas and LNG) business environment in 2020 was adverse. Two factors disrupted the foundations of the global oil and gas industry. First, the COVID-19 global pandemic caused an unprecedented reduction of demand that combined with high levels of production resulted in oversupply of oil, gas and LNG. This gap between supply and demand resulted in a collapse in commodity prices, reduced revenues and cancelling or deferral of investment. Second, societal awareness of the impact of climate change on planet Earth increased. Pressure to reduce carbon emissions and a concomitant societal-shift against carbon-emissions intensive petroleum-based forms of energy generation intensified. Many major players in the petroleum industry re-framed their strategies to focus on energy supply in general and in some cases plan to cease their exploration, development and production activities in the coming decades. In Australia, in part global factors manifested in the deferral of investment decisions on three LNG investments. The Australian Government signalled that gas developments would be a critical part of Australia’s post-COVID recovery and that management of abandonment and decommissioning liabilities would be a factor in the approval of transactions leading to a change in ownership. This paper will describe each of the factors faced by the industry in 2020 and frame the issues facing the petroleum industry in 2021 and beyond.

As the main force component on the aeroengine, casing is one of bases of the whole aeroengine, but it is extremely difficult to analyze the capacity of aeroengine casing impact resistance. An experimental and simulation study of impact resistance has been conducted on sandwich structures casing with aluminum honeycombs to identify and improve aeroengine casing impact resistance. Firstly, a Rent–Ipson model has been applied to analyze the energy of broken blades with impacting casing. Based on a sensing test technology, the experimental research on the impact of aluminum honeycomb sandwich panel with a conical head shape bullet and a hemispherical head shape bullet have been carried out. The experimental results provide a basis for subsequent simulation research. Then the impact resistance have been compared and analyzed from single structure casing, double layer structure casing, and sandwich structure casing, according to their loss of blade kinetic energy, casing deformation, and the variation of casing internal energy. Finally, the variation of energy has been discussed during blade impacting casing with various oblique angles. Our results show that the impact resistance of sandwich structure casing is better than single structure casing and double layer structure casing. Most importantly, the impact resistance of casing has been improved with the increase of blade impact oblique angle.

AbstractIn this work, extensive reactive molecular dynamics simulations are conducted to analyze the nanopore creation by nanoparticles impact over single-layer molybdenum disulfide (MoS2) with 1T and 2H phases. We also compare the results with graphene monolayer. In our simulations, nanosheets are exposed to a spherical rigid carbon projectile with high initial velocities ranging from 2 to 23 km/s. Results for three different structures are compared to examine the most critical factors in the perforation and resistance force during the impact. To analyze the perforation and impact resistance, kinetic energy and displacement time history of the projectile as well as perforation resistance force of the projectile are investigated. Interestingly, although the elasticity module and tensile strength of the graphene are by almost five times higher than those of MoS2, the results demonstrate that 1T and 2H-MoS2 phases are more resistive to the impact loading and perforation than graphene. For the MoS2nanosheets, we realize that the 2H phase is more resistant to impact loading than the 1T counterpart. Our reactive molecular dynamics results highlight that in addition to the strength and toughness, atomic structure is another crucial factor that can contribute substantially to impact resistance of 2D materials. The obtained results can be useful to guide the experimental setups for the nanopore creation in MoS2or other 2D lattices.

This article discusses the impact of the Alberta Land Stewardship Act – enacted by the Government of Alberta with the goal of developing an overarching land use policy to manage all lands and natural resources in the province – on Albertans generally, as well as the oil, gas, and oil sands industries. Although the implementation of the Act is in its early stages, the article nonetheless argues that the Act, and the authority that it grants, will significantly alter the way that land use decisions are made in Alberta and, of specific interest to those in the oil, gas, and oil sands industries, the manner in which proposed projects are reviewed and approved.

Introduction. The use of composite materials in agricultural engineering is known as one of the recommended ways to reduce the weight of the structure and protect against corrosion. The main disadvantages of such products are their low resistance to shock loads that occur during operation. The aim of this study is to develop a glass composite multi-layer structure of the trailer side, capable of withstanding shock loads along with statically applied forces, without including additional reinforcing metal elements in the zones of the possible impacts. Materials and Methods. To increase the impact resistance of the product (after an analysis of modern design solutions) the use of visco-elastic non-Newtonian fluids based on polysilicon by introducing an additional layer into the power element to compensate for impact effects is proposed. Results. On the basis of laboratory testing using statistical processing of the obtained data, the basic mechanical characteristics of non-Newtonian fluid (polysilicon) during impact tests (density, Poisson’s ratio, Young’s modulus, shear modulus) are determined, and graphs of the obtained dependencies are constructed. The temperature of the tested polysilicon samples did not significantly affect their mechanical properties. It is established that starting from the value of relative deformation 0.042, during the impact polysilicon shows linearly elastic properties. Discussion and Conclusion. Based on the received mechanical characteristics, the conclusions about resistance to shock loads of polysilicon as a component of a trailer board element are made. The variant of arrangement of the trailer board structural solution as a multilayer sandwich element with external parts made of polymer composite material with internal filling with fiberglass cells and polysilicon placed in large cells is offered.
