Design of Natural Gas Transmitting Pipeline (A Case Study of a Typical Gas Transmitting Pipeline for Domestic Use in Libyan Benghazi City)

The research paper focuses on the design of a natural gas transmission pipeline for providing home gas in Benghazi city. The study utilizes advanced technologies in gas transmission, specifically natural gas pipelines. The research methodology involves the collection of secondary data on gas sales, which includes flow rate, pressure, and temperature. An empirical study is conducted to analyze the gas properties and calculate the physical characteristics necessary for pipeline design. To design the gas pipeline, hydraulic design formulas from recognized standards such as ASME B31.8 and API 5L are employed. These formulas are used to calculate various parameters critical to the design process, including pipe diameter, pipe wall thickness, schedule number, maximum operating pressure, burst pressure, and hydro test pressure. The calculated values for these parameters are determined as follows: pipe diameter of 12 inches, pipe wall thickness of 0.157 inches, schedule number of 10, maximum operating pressure of 1133.85 psi, burst pressure of 1968.5 psi, and hydro test pressure of 1417.3 psi. To ensure accuracy and precision, it is recommended to simulate the designed pipeline using appropriate software or programs. This simulation process will verify the convergence of all the designed parameters, confirming the feasibility and efficiency of the pipeline design. By employing simulation, any potential issues or discrepancies can be identified and addressed before the actual construction of the gas transmission pipeline.
