GGS - High Accuracy LNG Sampling System for Custody Transfer

SHARE

Accurately determining the composition of Liquefied Natural Gas (LNG) is crucial, particularly for custody transfer applications. GGS specializes in designing and fabricating high accuracy LNG sampling systems that are compliant with GIIGNL, EN 12838, and ISO 8943 standards. The system involves transforming a liquid LNG sample into a homogenous gas sample for precise analysis. This is achieved using a gas chromatograph (GC) for natural gas. The capability of the LNG Probe Vaporizers ensures that the LNG vaporization process is seamless. GGS integrates complete sampling cabinets equipped with LNG sampling bottles, along with probe installations in transfer lines and conditioning systems. These solutions help plant operators obtain accurate data on natural gas composition, heating value, and density. As an independent system integrator, GGS customizes solutions to meet specific customer requirements and internationally accepted standards.

In order to obtain an accurate analysis of LNG, it is essential to have the right sampling system.
 
The accurate and traceable determination of LNG compositions is crucial for the custody transfer.
 
For natural gas, the most widely used method for measuring the composition is using a calibrated gas chromatograph (GC), but in the case of LNG sampling from the liquid and transferring it into a homogenous gaseous sample is a demanding and challenging extra step in the analysis.
 
Finding the most effective LNG Probe Vaporizer and an analyzer solution is not easy.

GGS is an independent system integrator, we can help you choose the best LNG Probe Vaporizer and analyser system for your application.

GGS provide LNG sampling and LNG analysis systems with a wide variety of gas analyzers and solutions. 
 
GGS designs and fabricates Sampling systems for LNG sampling for on-shore & off-shore projects.

We have the capability to design and engineer complete Sampling systems to meet the customer’s specific requirements and internationally accepted standards 
 
Sampling and vaporization of liquefied natural gas. Complies with GIIGNL, EN 12838 and ISO 8943 standards, both intermittent and continuous Sampling. 
 
LNG quality and composition of the liquid is determined by taking a representative sample of LNG (liquid) and ensuring proper conditioning for its analysis.

We design and integrate complete Sampling Cabinets for the LNG sampling that includes the LNG sampling bottles collected through Sample Probe installed into the LNG transfer line and sample conditioning systems.

The sampling of LNG or Natural Gas is really critical for the plant operators, to determine accurately the composition of the Natural Gas and its Heating Value and other characteristics, like density.
