DRIVER OPTIONS FOR PIPELINE COMPRESSORS: GAS TURBINE, IC ENGINE & ELECTRIC MOTOR
Most compressors in pipeline service utilize gas turbines, electric motors, or reciprocating engines as their mechanical drivers. The selection of which of these drivers is the most appropriate for a given application depends on the operating/performance profile requirements, the available utilities, the initial cost and operating budgets, the site conditions and the type of compressor. This technical paper will discuss each of the driver options for typical pipeline applications, their principal components, functions, features, operating characteristics, as well as their advantages and disadvantages for a given application. Hardware options and failure modes will also be discussed. Example pipeline case studies will be presented for each driver type, specifically outlining the operators decision-making criteria for the selection of the driver given the application. Standard API and ISO specifications for each will also be discussed.
