Operating cost analysis aids gas turbine selection. G.K. Roy. Hydrocarbon Processing, February 1998, 77(2), 73--77.

A survey of the design life of gas turbines suggests that at least 70% of the operating costs are for fuel. Data for four different operating scenarios for a typical plant are analysed and spreadsheets show considerable variations in total costs. The various options are reviewed and plant design features are described and illustrated. In the four options discussed the fuel quality varies from No. 2 diesel fuel to a heavy oil with a viscosity of 300 cSt at 50 degrees C. The latter contains trace metals and burning this oil requires preheating, purification, water washing, and inhibition. These treatments significantly increase the operating costs.
