The customer, a key producer in the region and long-term user of reciprocating compression equipment, recognized the benefits of centrifugal compression and looked to Siemens for a fully integrated, turnkey solution that includes compressors, motors, variable frequency drives, and associated process equipment.
Each train consists of a 22,000 hp motor, gearbox, and multi-stage Dresser-Rand DATUM centrifugal compressor, all mounted onto a single skid. The compressors, motors, and drives will all be built by Siemens in the U.S. It is scheduled for commissioning the latter part of 2020.
Mid-size gas treatment plants traditionally use reciprocating compressors driven by electric motors or gas engines. However, with the increase in production from shale plays, larger gas plants – in the range of 200-300 MMcfgd–are being constructed, forcing gas processing companies to consider alternative compression solutions in order to reduce costs, footprint, and maintenance.
The high efficiency of the DATUM compressors, coupled with their easy maintenance, was a major factor for selecting this configuration. With a DATUM fleet availability of more than 99.7%, the plant will have minimum downtime despite the un-spared compressor configuration and will ensure minimal loss of production, bringing significant value to the customer in meeting contractual production guarantees.
