Dresser-Rand introduces newest DATUM centrifugal compressor
HOUSTON -- Dresser-Rand has introduced the latest model in its line of DATUM centrifugal compressors, and has sold the 1,000th compressor, the DATUM I, to PEMEX to supplement capacity on its existing Abkatun-D platform, in the Bay of Campeche’s Tabasco Field.
Recent changes in Mexican environmental regulations required PEMEX to reduce, and eventually eliminate, gas flaring on its offshore platforms. In order to comply with this requirement, additional compression capacity was needed on its Abkatun-D platform, to move the gas to a downstream collection point.
Dresser-Rand recommended using two single-lift compression trains, each containing two DATUM compressors driven by VECTRA power turbines. The DATUM unit in low-pressure service on each module is configured as a double-flow machine, and provides the inlet flow capacity of a compressor much larger in size. In high-pressure service on each module, the DATUM I compressors incorporate proprietary rotary separator technology within the compressor body, to remove liquids from the incoming gas stream, eliminating the need for conventional external separation equipment.
The DATUM I compressor is part of the DATUM ICS (Integrated Compression System). The DATUM ICS integrates rotary separator technology, together with a high-speed, close-coupled, gas-cooled motor; magnetic bearing rotor system; dedicated unit controls; process coolers, valves, instrumentation and
The order from PEMEX was booked in the fourth quarter of 2012. Dresser-Rand will engineer, fabricate, install and test the two compression modules, with an expected delivery to Pemex in early 2014.
