H₂O, H₂S, CO₂, and O₂ measurements for pipeline integrity

Measurement of H₂O, H₂S, CO₂, and O₂ in natural gas pipelines at production and gathering sites, custody transfer points, compression stations, storage facilities, and in distribution systems is critically important to protect pipelines from corrosion and meet gas quality specifications.

Our expertise in the field

Tunable Diode Laser Absorption Spectroscopy (TDLAS)and Quenched Fluorescence (QF) analyzers have proven to be highly effective for continuous on-line monitoring of these contaminants in natural gas pipelines.

Chemical injection skids for gas pipelines

Chemical injection plays a vital role in the safe and efficient production and transport of natural gas. Corrosion inhibitors are injected into pipelines to maintain and extend the lifetime of gas pipelines, while kinetic hydrate inhibitors (KHIs) and methanol are used to prevent the formation of crystalline ice-like structures (Hydrates) that can plug pipelines and disrupt gas flow. The effectiveness of these inhibitors depends on injecting the right amount of chemicals.

LNG tank gauging & operational safety

A typical liquefied natural gas tank requires a range of instruments to measure liquid level and density, liquid and vapor temperature and pressure, skin temperature and more. For safe operation you must also make sure that two layers of different LNG densities are not rapidly mixing with the effect of releasing large amounts of gas – known as rollover.
