Natural gas corrosion inhibitors

■Product Overview
XA-15 natural gas corrosion inhibitor is mainly composed of heterocyclic amide with low boiling point, which has good gas-liquid two-phase dispersion, and has good anti-corrosion effect for H2S and H2S in water-dissolved liquid H2S-H2O system formed by gas-liquid two-phase comprehensive corrosion. To ensure the effective concentration of the agent, the corrosion inhibition rate can reach ≥95%, and can effectively control local corrosion. It is especially suitable for the anti-corrosion of natural gas gathering and transportation trunk lines, compressor stations and oil and gas wells with high water content and H2S.

■Performance characteristics
It has good gas-liquid two-phase dispersion and anti-corrosion effect.

■Technical indicators
Project indicators
Appearance: Homogeneous liquid
pH (1% aqueous solution) 5-9
Solubility: Alcohol-soluble and water-dispersible

■Product use
This product can be used in gas production wells, compressor stations and natural gas gathering and transportation pipelines. Generally, it is diluted with low carbon alcohol and injected into the pipeline system with a metering pump or directly injected into the gas well casing. According to the content of H2S gas and corrosion on site, the size of the chemical dose can be adjusted, and 200~500ppm natural gas corrosion inhibitor can be added according to the amount of condensate in natural gas. For the gathering and transportation system and sewage treatment system, the system used for the first time needs to be pre-filmed, and the pre-film concentration is 500mg/L.
