Flow Variables

A progressive cavity pump (PCP) is a positive displacement pump and has been used as an artificial lift method in the oil and gas industry for pumping fluid with solid content and high viscosity. In a PCP, a single-lobe rotor rotates inside a double-lobe stator. Articles on computational works for flows through a PCP are limited because of transient behavior of flow, complex geometry and moving boundaries. In this paper, a 3D CFD model has been developed to predict the flow variables at different operating conditions. The flow is considered as incompressible, single phase, transient, and turbulent. The dynamic mesh model in Ansys-Fluent for the rotor mesh movement is used, and a user defined function (UDF) written in C language defines the rotor’s hypocycloid path. The mesh deformation is done with spring based smoothing and local remeshing technique. The computational results are compared with the experiment results available in the literature. Thepump gives maximum flowrate at zero differential pressure.

The article presents the characteristics of characteristic oils of the Apsheron oil and gas region, as well as the hydrocarbon composition of light and oil fractions. Oils of the Apsheron oil and gas region in terms of light fractions, sulfur content, and density are comparable to marketing grades of oils. The standards for prices are: graded crude oil WTI, Light Sweet, Brent, and Russian oils Sokol, Urals, Siberian Light are approaching them. We have studied in detail the yields and hydrocarbon composition of light and oil fractions of oils from the Apsheron oil and gas region. To obtain oils with a high viscosity index, studies were carried out to change the structure of oil fractions using hydrogen using the example of oil fractions of Azeri oil. Due to the significant content of aromatic hydrocarbons, schemes for the processing of oil fractions have been developed, including selective purification of distillates, dewaxing (except for Guneshli oil), as well as hydrocatalytic treatment in a severe mode in the presence of industrial Russian catalysts. As a result, it was possible to obtain API group I oils, according to the viscosity classification corresponding to SAE 20 and SAE 30. Thus, a study of the qualities and hydrocarbon composition of oils from the Absheron oil and gas region showed that these oils are characterized by a high content of light fractions, low density, and low sulfur content. According to these indicators, these oils correspond to the marker oils. In order to obtain base oils with a viscosity index of ≥90 and an aromatic hydrocarbon content of ≥10, a traditional refining method was used: selective refining, dewaxing, and severe hydrotreating.

A few pipelines transport different unsafe items, for example, synthetic concoctions, profoundly unstable fluids, and anhydrous alkali, or carbon dioxide. As per information from the 2018 NHIS-OHS, laborers utilized in mining and oil and gas enterprises had high commonness paces of introduction to conceivably unsafe work association attributes and risky synthetic compounds gas spills. In our task we are intending to recognize the careful area of the break. A gas spill locator is a gadget that identifies the nearness of gases in a region, as a major aspect of a word related security framework. This kind of hardware is utilized to identify a gas spill, warmth, fire and different emanations and can interface with a human. A controller can sound an alert to human in the region where the variation from the norm is happening, allowing them the chance to find the break without human hazard. This kind of gadget is significant in light of the fact that there are numerous gases that can be hurtful to human. This undertaking measures and alarms the specialist from this risk. The locator unit will be versatile vehicle based gear. This unit will move alongside the pipe line, screen the air and gives ready messages. The versatile security framework will consistently quantify the warmth, CO and H2S level in the environment or in shut zones where human are working[19],[20],[21]
