Streszczenie:

Asphalt mixtures were immersed in the fuel oil to study the oil corrosion resistance. The mechanical performance of asphalt mixtures in the oil was evaluated by the observation, mass loss measurement, Marshall stability test and splitting strength test. Effects of immersion time, binder types, and anti-oil corrosion additive content were analyzed. It is found that there is the evident stripping after immersing the mixture in the oil. The stability test and strength significantly decrease. Using the anti-oil corrosion additive can effectively improve the mechanical performance of asphalt mixtur

Research results in recent years show that there are specific problems associated with blending different types of crude oil. Incompatibility of mixed oils, in particular, can lead to clogging and sometimes even shutdown of pipeline systems.

Reclaimed asphalt pavement (RAP) has been utilized as a potential partial substitute for virgin asphalt binder in asphalt mixtures. However, a primary concern with increasing RAP content in asphalt mixtures is the cracking potential, attributed to the aged RAP asphalt binder (RAP-binder). To address this, the use of petroleum-based and bio-derived recycling agents (RAs) in enhancing the cracking resistance of high-RAP asphalt mixtures has been explored. The objective of this study is to ascertain the effectiveness of six RAs in mitigating cracking in high-RAP asphalt mixtures. The RAs consider

Tribology is a high demand mechanical system with friction and wear. Mechanical systems lose efficiency as a result. One answer for this issue is to utilize an oil that can limit contact and wear, bringing about improved effectiveness. The advancement of effective lubricating added substances for tribological properties improvement and improved thermal conductivity has gotten huge modern and scholarly consideration. By and large, nano-sized particles scattered in lubricants, referred to as nano-based lubricant, are utilized in mechanical structures to lessen heat and forces of frictions. Moreo

Abstract A formulation of safe products was developed and 4 pilot batches of bitumen were obtained in small quantities - replacing binders from local waste of oil and fat and oil production. The origin and characteristics of the used local waste and additional components are considered. A scheme for obtaining a bitumen-replacement mixture for the use of insulating and roofing coverings has been developed. Experiments on the utilization of local waste by the physicochemical process and the process of raw material oxidation have been carried out. Experimental batches of bitumen-replacement mixtu

Regeneration agents play a critical role in modifying the mechanical properties and durability of RAP asphalt mixtures. This paper aimed to develop a castor oil-based asphalt regeneration agent. The effects of this regeneration agent on the pavement performance of laboratory-aged asphalt and an RAP asphalt mixture were comparatively studied by a series of laboratory tests. For the developed castor oil-based asphalt regeneration agent, the weight ratio of the castor oil to dibutyl phthalate was determined as 1:4. Moreover, the regeneration effectiveness of the castor oil-based regeneration agen

There are numerous instances of technical importance in which multicomponent lubricants are utilized either by design or by necessity. In many of these cases one of the components is a liquid while the other component is a gas, as in squeeze film dampers during high frequency operation, or both components are liquids, as in the oil-water emulsion used in metal forming processes. In this paper our objective is to develop a self-consistent theory of hydrodynamic lubrication with bicomponent, liquid-liquid lubricants.

Three-dimensional superhydrophobic/superlipophilic porous materials have attracted widespread attention for use in the separation of oil/water mixtures. However, a simple strategy to prepare superhydrophobic porous materials capable of efficient and continuous separation of immiscible and emulsified oil/water mixtures has not yet been realized. Herein, a superhydrophobic graphene/polystyrene composite material with a micro-nanopore structure was prepared by a single-step reaction through high internal phase emulsion polymerization.

The separation of fluid-fluid mixtures is a major issue in various sectors. The liquid-liquid hydro-cyclone has a wide range of applications in various sectors due to its great efficiency in separating fluid mixtures, ease of installation, and low cost. In crude oil production, high water is consumed following the degrading of production quality, high processing costs, costs, and environmental impacts.

The separation of oil emulsions is an important step in the purification of crude oil from water, mineral salts, and various associated contaminants, asphaltene-resinous substances, and paraffin contained in the oil. In the formation and stabilization of oil emulsions in the form of colloidal particles in the oil, insoluble dispersed solids also have a high effect. Examples of such substances are microcrystals of solid paraffins, asphaltenes, ferrous sulfides, and other mechanical mixtures. These substances form a strong mechanical barrier on small water droplets distributed in the oil phase,

There may also be a situation in which the areas of lubrication lack lubricant and the lubrication of the friction pairs will be carried out by only the refrigerant. The requirements related to legal regulations and concerning refrigerants result in the return to the use of natural substances such as hydrocarbons.
