Abstract:
Natural gas is one of the valuable non-renewable resources in the country, which after sweetening and separation is transferred through pipelines for industrial and domestic use. Since the pressure of the transferred gas decreases due to various factors including friction, slope, etc., along the pipeline, Gas Compression stations are utilized. Operators of gas compression stations urgently need to prioritize the equipment to provide a repair and maintenance plan for the equipment and avoid spending huge inspection costs. In this study, an optimal model for examining and prioritizing critical equipment has been presented. In addition to being quantitative, it also includes more details based on the criteria of safety, health, and environment (HSE). Using the multi-criteria decision-making method, TOPSIS, which generally prioritizes the investigated objectives (equipment) in order of proximity to the ideal solution, it was shown that the turbine, compressor, and scrubbers are the most important (critical) equipment used in stations. Also, the obtained results were compared with the model provided by the gas transmission company, based on which the proposed model, due to its quantitative nature, its use of new decision-making methods, comprehensive details, and prioritization of the studied criteria is a more reliable model than the model of the gas transmission company.
