Various types of chemicals are used by the oil and gas industry to maintain the production flow of the wellbore. Some top chemicals are biocides, oxygen scavengers, corrosion inhibitors, and H2S scavengers.

Arex company for chemical industries offering those chemicals with a high quality performing and competitive prices.

H2S Scavengers  are one of the most common chemicals that are outsourced by many oil and gas companies.

 Arex H2S Scavenger product:

  • Arex HSS Hydrogen Sulphide Scavenger

H2S Scavengers:

A hydrogen sulfide (H2S) scavenger is a specialized chemical or fuel additive widely used in hydrocarbon and chemical processing facilities. These specialized chemicals react selectively with and remove H2S to help meet product and process specifications.

Products treated for H2S include crude oil, fuels, and other refined petroleum products in storage tanks, tanker ships, rail-cars and pipelines.

Hydrogen sulfide can cause damage to pipework, either by reacting directly with steel to create an iron sulfide corrosion film, or by increasing the acidity of the liquid/gas mixture in the pipes. When dissolved in water, H2S may be oxidized to form elemental sulfur. This can also produce an iron sulfide corrosion film when in direct contact with the metal surface. Therefore, it is essential to remove H2S from crude oil as quickly and efficiently as possible.

H2S Scavengers Application:

Scavenger programs are selected depending on the nature of the H2S problem being addressed and the petroleum product being treated.

  • Water-soluble scavengers – The most common scavengers and often the product of choice for applications at temperatures below 200°F (93°C). These are the preferred additives for use in flare gas, LPG, residues and crude oils.

Arex is responsible for producing certain types of chemicals after analyzing and preparing them in their high-end technical lab. Before these chemicals are dispatched to the oil and gas agency, they go for quality check to eliminate any potential problems.
