Gas analysis helps to control LNG purity

Natural gas contains a small amount of moisture, carbon dioxide, and sulfur compounds, all impurities are removed through gas treatment processes. Pipeline corrosion from acid impurities, such as CO2 or H2S in the presence of water, must be also avoided from a safety point of view. Gas analysis helps ensure these contaminants are removed effectively, protecting product quality and safeguarding pipelines.

Reliable systems for safety monitoring

LNG vapors are flammable in concentrations of 5 to 15 percent in air, so gas analysis is essential for safety measurements during LNG transportation. The regulations for this application insist on redundancy within each system, so at least two Paramagnetic oxygen analyzers are specified. These can also be used for safety measurements at the LNG storage tanks before and after transportation.

Trusted solutions to suit your LNG process

Servomex offers gas analysis measurements across the liquefaction process through the rugged and flexible SERVOTOUGH SpectraExact 2500. This reliable, accurate, and stable real-time online photometric analyzer uses Infrared and Gas Filter Correlation sensing technologies to provide measurements of carbon dioxide, hydrogen sulfide, and water in amine for control and quality measurements. Designed for ease of use, the SpectraExact 2500 is suitable for demanding process applications, including monitoring continually flammable sample streams in hazardous areas.
