T1.9 Distributed LNG Production: LNG from any gas source

As Liquefied Natural Gas (LNG) was originally developed as a means for transporting natural gas across markets, liquefaction plants were well above the needs and financial capacity of any private company. In addition, the storage of large volumes of LNG involved, in many cases, a high degree of boil-off and, as a consequence, emissions. All these issues prevented the widespread adoption of LNG among high horsepower (HHP) consumers, in spite of the lower price of this fuel and its environmental benefits. The same barriers, along with the cost of laying gas pipelines, prevented the gasification of small and outlying communities.

To address the needs of those consumers, in January 2013, Galileo Technologies introduced its LNG production station, which packages all the capabilities of a large scale LNG plant into one compact and mobile unit. This milestone was accompanied by the introduction of a gas conditioning plant, which widens the sources available for liquefaction: from sources with high content of CO2, such as biomethane, to even simpler gas compositions that require minimal dehydration.

Both units measure the size of a 40 ft. sea container and can be delivered over two separate trailers to be connected on to natural gas mains, biodigestors, or wellhead equipment in a distant oil & gas field. No crane is necessary. The outcome of this new technology is a Distributed Liquefaction model, which liquefies every type of gas right at the source in any location and enables distribution logistics that are equal to liquid fuels. This makes clean gas fuels available without the need of laying pipelines, by extending the reach of current natural gas infrastructure or by shortening the distance between new gas sources and consumers.

Due to their packaged trailer mounted configuration, the installation and commissioning of both units only require a ground level, air compressed supply and an internet connection. Every liquefaction unit supplies 10,000 gallons (15 tonnes) of LNG per day. This installed capacity can grow at the pace of demand, through the progressive addition of liquefaction modules, even until reaching the volume of LNG produced by a mini LNG plant. The gas conditioning plant is already prepared for these growing processes, due to its design for working with clusters of one or several liquefaction units simultaneously.

In Vaca Muerta, Argentina, these units produce LNG from on-site gas flare reduction and abandoned or orphan wells; the LNG is then transported via virtual pipeline to the first gas-fired power plant that does not require conventional pipelines in the country. The price per MW from distributed power generation is even lower than the price offered by the other conventional gas-fired power plants of the national system: USD 4.2 vs. USD 7. The trucks that tow the cryogenic ISO containers of the virtual pipeline also run on LNG. This whole small-scale LNG operation eliminates gas flaring at the wells and reduces CO2 emissions on every stage: from the exhaust of the trucks by 20% and from power generation by 30%.
