The BOS Compressor: An Economical Compressor Developed to Serve the Higher Speed, Higher Rod Load, and Higher Horsepower Requirements of the Gas Pipeline, Storage, Gathering, Process, and Similar Industries

Traditionally, large slow speed integral gas engines were used in Pipeline applications. Today, the need exists for smaller high-speed units with a lower total installed cost and quicker return on investments. Utilizing well over 100 years of gas compressor experience, Dresser-Rand has developed a new Big Oilfield Separable (BOS) frame and Dresser-Rand Advanced Reciprocating Technology (DART) cylinder line-up to serve the high-speed engine and motor driven Pipeline/Injection markets. By incorporating a longer stroke capability, this compressor also serves the electric motor driven Process Gas markets. First, this paper will identify the complete design, development, and test verification of the frame and running gear. Second, this paper will then identify the complete design, development, and performance verification of the DART cylinder. Together, the BOS frame and DART cylinders provide an economical replacement to the older slow speed integral gas engines that are utilized in Pipeline applications.
