Dresser-Rand commissions micro-scale LNG system

Published on: 

Siemens’ Dresser-Rand business recently commissioned an LNGo-HP (highpressure) micro-scale natural gas liquefaction system for Altagas Ltd. in Dawson Creek, British Columbia, Canada. The modular, expandable LNGo technology enables efficient installation, especially in a demanding environment like Dawson Creek.

The Dawson Creek facility, with a capacity of approximately 30,000 gallons of LNG per day, commenced production on January 25, 2018. The scalability of the LNGo system enables the customer, Altagas, to scale production in line with demand and minimize capital expenditures. The LNGo-HP system allows consumers to convert from diesel and other fuels to natural gas which provides the benefit of a smaller carbon footprint, lower operational cost, and market price stability.


Siemens’ scope of supply included one LNGo-HP system, site civil works, building construction, mechanical and electrical integration, commissioning, startup, and operator training. The LNGo system consists of modules which include two Siemens gas engines, two Dresser-Rand MOS reciprocating compressors, three Siemens MV motors, Siemens variable frequency drives, and associated auxiliaries. The plant, with a footprint of approximately 2,500 square meters, was deployed directly at the site.
