The high-pressure and low-temperature environment prevailing in the process of offshore oil and gas development is very prone to the formation of hydrate in the wellbore to block the tubing, which leads to production reduction and shutdown and causes…
Hydrodynamic cavitation process can produce extreme physical conditions such as local high temperature, high pressure, high jet flow and strong shear stress. Therefore, applying the hydrodynamic cavitation device to upgrade Saudi heavy crude oil is…
The improvement of the physicochemical properties of heavy crudes for their better use has brought the application of new technologies and processes to the oil and gas industry. Hydrodynamic cavitation consists of cavitating the working crude oil as…
Power ultrasound, as an emerging green technology has received increasing attention of the petroleum industry. The physical and chemical effects of the periodic oscillation and implosion of acoustic cavitation bubbles can be employed to perform a…
A natural gas transportation pipeline with a gaswater two-phase flow containing CO2 is prone to severe flow-assisted corrosion (FAC). The accumulation location of the water phase in the pipeline and the wall shear stress distribution are important…
In article authors have investigated a question of a possibility of application of hydrodynamic cavitation processing of crude oil for the purpose of decrease in content of sulphurous compounds. The electromechanical converter with a secondary…
With the increasing requirement of global energy resources, researchers seek for new ways to deal with unconventional crude oil resources. Using the Computational Fluid Dynamics numerical simulation method, the standard k- turbulence model and the…
The high-pressure and low-temperature environment prevailing in the process of offshore oil and gas development is very prone to the formation of hydrate in the wellbore to block the tubing, which leads to production reduction and shutdown and causes…
Background The refining process aims to eliminate the undesirable components in crude vegetable oil to yield refined oil with improved stability and consumer preference. The refining process can be conducted chemically (degumming, neutralization,…
