one of the most important methods of transporting natural gas in iran and other parts of the world is the utilization of a network of pipelines. compression station and turbo compressor units play an important role in gas supply through pipelines. one of the primary concerns in these units is the reduction of fuel consumption. by cooling of exhaust gas from the source station, the pressure drop...

Background: An ammonia gas explosion poses immediate health hazards such as respiratory tract burns, skin and eye irritation, and potential death within seconds. It also causes long-term negative impacts on biodiversity, affecting aquatic life and vegetation. An explosion in the Firuzabad sodium carbonate factory in Iran led to massive ammonia gas leakage and the poisoning of several employees....

Free-span occurs normally in a pipeline at uneven seabed, dynamic seabed and pipeline crossing. Free spanning in pipeline causes Vortex Induced Vibration (VIV) fatigue, fracture and bursting. In this paper, a pipeline located in South Pars Gas Field is assessed against local buckling and VIV fatigue using probability of failure theory based on the recommended methodology by Det Norske Veritas (...

The authors have deeply been interested in concerns about health, safety & environment (HSE) in recent years. HSE demands in engineering, particularly at the design and construction stages, are becoming stricter and stricter. In oil and gas plants, many pieces of equipment, and much of the piping, treat highly flammable gases, such as natural gas, methane, propane and hydrogen, which if release...

Abstract To reveal the flame propagation and CO/CO2 generation characteristics of coal dust explosion, lignite cloud is studied through experiment numerical simulation in a horizontal pipeline apparatus. The result indicated that within 0.5 s after distance rapidly increases until explosion reaction sufficient. FLUENT used to simulate characteristics. It found error acceptable consistent with e...
