Dresser-Rand Hits 1000th Datum Sale

Company's Datum I becomes milestone compressor model; goes to Pemex

Posted on May 6, 2013

Dresser-Rand has sold its 1000th Datum centrifugal compressor – the Datum I centrifugal compressor – 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, the company said.

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, which is part of the Datum ICS (Intergrated Compression System), in the second compression train was identified as the 1000th Datum compressor sold.  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 interconnecting piping – all packaged in a compact module design.

 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.
