LGN FGSS represents an acronym describing a LNG fuel gas supply system. This infrastructure has become increasingly ubiquitous as an efficient mode to transport LNG to certain facilities in need of a particularly strong source of LNG.

As the uses of LNG continue expanding, the need to access reliable cryogenic equipment becomes key for optimizing companies operations. Find out how a LGN FGSS works exactly and how to meet the cryogenic engineering partner that will enable full efficiencies.

How does a LNG FGSS work?

Put briefly, a LNG FGSS works in the following manner: the infrastructure guarantees the flow of gas from high-pressure areas to lower-pressure areas. This fundamental working allows LNG to travel from the natural gas well to the desired destination, through a system of pipes. 

A more detailed description of this work starts at the gathering structures. These are in charge of moving the gas to the pipelines thanks to the use of compressors, which are typically propelled by internal combustion engines or turbines and which can use natural gas as fuel.

A processing facility might be included to remove impurities from the substance, which may include water, sulfur, carbon dioxide or helium, among others.

The LNG then moves into the transmission system, in charge of moving large amounts of this substance across the territory. The pipes must ensure correct pressurization to guarantee top quality and efficiency in their transportation. In order to do so, compressor stations are found at constant intervals following these pipes, ensuring pipe pressure remains adequate and safe. 

These stations can also lower compression in order to slow down the transmission of LNG, effectively acting like storage options to help companies match a decreasing demand gor this substance.

LNG then reaches local gas utilities, where it’s met with gate stations. These are in charge of minimizing pressure to ensure the values are adequate for local distribution; they also add odorant to LNG to increase safety in case of leaks; they’re also in charge of measuring the gas flow rates.

Local stations are also the place where the flow from higher to lower pressures is regulated via relief valves, among other key equipment. This is also the place where network capacities are evaluated in order to ensure minimum service disruptions.

LNG fuel gas supply systems uses

The LNG fuel gas supply system represents one of the key systems today facilitating the use of LNG for several industries. 

One of its crucial applications is the transportation of LNG to consumers with a high demand for this substance, such as gas power plants. As such, the LGN FGSS generates the needed supply system to condition natural gas for its use in gas turbines or boiler units.
