Liquefied Natural Gas

Liquefied Natural Gas (LNG) is a cryogenic liquid form of natural gas with most of the heavy components removed (it is predominantly methane with some ethane, propane, and nitrogen). The liquefaction of natural gas allows its transportation over long distances without pipelines, typically using ships, rail, or trucks. The global trade of LNG is expected to double in the next ten years as natural gas exceeds 25% of global energy sources. LNG is used to supplement natural gas distribution systems (which typically rely on pipeline supplies), to generate electrical power, for meeting peak demands, and as engine fuel.

The energy content of LNG varies considerably depending on the composition of the source gas as well as the process used to convert the gas to a liquid.  Additionally, the average energy value of a bulk container of LNG changes with time, or ages, since the methane evaporates at a different rate than the other components.  These facts in combination with the difficulties associated with any cryogenic fluid (LNG has a boiling point of -162°C) make LNG an unusual and very challenging liquid to measure.

LNG Refueling Stations

Mustang Sampling has a long history of LNG sampling and continues to provide best-in-class technologies for small and large scale LNG custody transfer.  The patented Mustang Sampling Vaporizer provides the core for a variety of sample conditioning systems designed specifically for cryogenic service.  Mustang Sampling provides LNG Import & Export Custody Transfer solutions globally, peak shaving solutions, complete bunkering systems and LNG load rack solutions (truck transport).

Intermountain LNG Nampa Facility

Mustang Sampling provided a Mustang Intelligent Vaporizer Sampling System®, Mustang Sampling’s SoftView® LNG Monitor Software and a Gas Chromatograph for the plant to monitor not only the LNG Intermountain was processing, but also what it was selling and storing.
 

Intermountain Nampa LNG

Gas arriving at the Intermountain facility requires a liquefaction process to convert to LNG. The gas is processed to clean it, separating it from water, impurities and other associated liquids. Prior to the cleaning process samples are extracted from the natural gas pipeline via a Pony® heated probe enclosure, prepped by a Mustang® P53® Sample Conditioning System then sent to a Gas Chromatograph for analyzation. Once the sample verifies that the gas meets Intermountain’s quality standards the natural gas is converted to LNG. 

Marine Bunkering

Mustang Sampling has a long history of LNG sampling, starting with efforts to import LNG into the United States during the 90’s.  Mustang Sampling continues to provide best-in-class technologies for small and large scale LNG custody transfer.  The patented Mustang Sampling Vaporizer provides the core for a variety of sample conditioning systems suitable for cryogenic service.

Mustang Sampling provides LNG Import & Export Custody Transfer solutions globally, peak shaving solutions, complete bunkering systems, and LNG load rack solutions (truck transport).  Mustang Sampling products include Certiprobes, vacuum jacketed tubing, vaporizers, composite sample systems, manual sample systems, and custom software.

Behind the Scenes at Harvey Marine

To support the development of the LNG fueling facility, Harvey Gulf International Marine needed to secure a partner who had in-depth expertise and knowledge of LNG Shore to Ship Bunkering Stations, a partner that understands the methods for continuous and intermittent sampling of LNG as well as sample probes, sample vaporizers, sample holders and sample cylinders. That PARTNER is MUSTANG SAMPLING.

FSRU Custody Transfer

The composition of LNG varies considerably depending on its source, storage, and age. Since cargos are typically traded per total energy content, the value of the fuel increases or decreases as the composition of the LNG changes. The fuel may also become unsuitable for some applications if the portion of methane, or “methane number”, falls outside certain ranges.

Offshore applications create unique and difficult challenges especially in the sampling and analysis of LNG while both loading and unloading the fuel.

How To Tackle The Challenges Of LNG, NGL Sampling

If not controlled properly, liquids and gases can coexist within the process and sampling systems, each moving with a different velocity through the system, making it impossible to deliver a representative sample to the analyzer.

Cryogenic Experiences Applied To LNG Sampling Research

LNG sampling R&D depends heavily on a core knowledge of cryogenic design principles.
