Offshore Rig Flare-up Control System Highlighted

Dresser-Rand notches up the sale of its 1,000th DATUM® centrifugal compressor.

The milestone was reached with the sale to Petróleos Mexicanos (PEMEX) to supplement capacity on its existing Abkatun-D Platform located in the Tabasco Field in the Bay of Campeche.

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 Dresser-Rand proprietary rotary separator technology within the compressor body to remove liquids from the incoming gas stream which eliminates the need for conventional external separation equipment.

The DATUM I compressor is part of the DATUM ICS (Integrated Compression System) which 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 interconnecting piping – all packaged in a compact module design.
