Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

Gas Turbine Compressor Unit Application in Sour Gas Field Operation [PDF]

Volume 3: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications; Cycle Innovations, 1986
The use of sour gas as primary energy requires constant supply pressure and flow to the gas treatment plant as well as to the pipeline distribution network and consumers. During exploitation of gas fields, when the well head pressure and flow decreases, production continues at increased cost. Application of gas compression
