Gas and Petrochemical CFD Training Package, for INTERMEDIATE

Description

Gas and Petrochemical ANSYS Fluent Training Package, 10 Practical Exercises for INTERMEDIATE Users

A petrochemical engineer’s main duty is to expand roads to break down oil and petroleum, then use the foundation components to extend everyday products like plastic, rubber, and synthetic fibers. Petroleum and Gas Engineering is a field of engineering interested in works related to the exploration, extraction, production, and processing of hydrocarbon, which can be either crude oil or natural gas. Instances of petrochemical fuels are liquefied petroleum gas (LPG), kerosene, diesel, gasoline, and jet fuels. Attend that a refinery produces other valuable products such as waxes, asphalts, plastic materials, lubricants, and greases.

There are lots of Gas and Petrochemical engineering projects that are simulated by ANSYS Fluent software using CFD methods. This CFD training package includes 10 practical exercises related to the Gas & Petrochemical Engineering field and industrial devices at the Intermediate level.

We start this training package with practical exercise number 1, which simulates borehole water flow. Borehole or drilling is making a hole or drilling a well on the ground, which is used to identify the type of soil in the area. Pre-construction drilling or borehole is used to determine the soil type and groundwater status and agriculture and oil and gas drilling operations.

In study number 2, using the DPM (Discrete Phase Model), the effect of impurities in the working fluid, and erosion on the body gas splitter was investigated. The impurity gas entered at a speed of 5 meters per second vertically and was directed out through 3 outlets. The impurity distribution, concentration, adsorption, and reflection in the installed filters were observed.

The goal of project number 3 is to simulate sludge flow settling in a pipe. The Eulerian multiphase model has been used. The water is entering the domain with a speed of 0.01 m/s with gravity considered -9.81 m/s-2 on the y-axis.

Simulation number 4 is modeling gas-particles movement through the convergence-divergence nozzle by a two-way DPM model. The nozzle is in grossly overexpanded condition. These kinds of nozzles are used in the gas and petrochemical industry.

A packed bed reactor, also known as a fixed-bed reactor, is often used for catalytic processes and is simulated in practical exercise number 5. A packed bed reactor (PBR) is preferred for heterogeneous reactions, where the solid-fluid contact dramatically influences the reaction rate. A PBR is a cylindrical vessel filled with solids (a reactant).

Practical exercise number 6 simulates multiphase flow in a porous medium and filter cake formation. Water flow with a relative pressure of 100,000 pascals and a temperature of 288.15 K enters from the top of a vertical column. It enters a porous media at the end of the column.

Flare (Petrochemical)

Problem number 7 simulates combustion in a gas flare system. The flare system, also known as a gas flare, is a combustion device used in industrial units such as oil and gas refineries and the production of oil and gas wells, especially in offshore platforms. Gas flares are responsible for burning the natural gases released during oil extraction in a completely controlled manner. Practical exercise number 8 simulates a two-step air-methane mechanism combustion in a gas flare in the presence of wind flow.  In fact, during the oil extraction process, some natural gas accumulates in a mass on top of the oil in the reservoirs. Therefore, it is better to try to collect and store natural gas, but if this is not possible, we should burn it.

DDPM (Petrochemical)

In project number 9, we simulated particle accumulation in a simple elbow bend using DDPM. However, the fast injection would result in a dense accumulation of particles. Therefore, a DDPM (Dense Discrete Phase Model) model is employed.

Industrial Shell and Tube Heat Exchanger

One of the most applications of shell and tube is in refineries.  this project aims to reduce the temperature of the oil. Finally, in project number 10, we have stimulated an industrial shell and tube heat exchanger. After simulating the present shell and tube, it was observed that this heat exchanger has the efficiency required in refineries.
