Chemtex’s Propylene Glycol Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways.



Metal surfaces are prone to corrosion very easily.But with the help of propylene glycol corrosion inhibitor this corrosion can be prevented. It buffers the organic acids formed as a result of glycol oxidation. Inhibited glycol based heat transfer fluids provides corrosion protection without reducing system’s heat transfer efficiency.

In Glycol system glycol is degraded from time-to-time,so it is very much important to stop this degradation.Glycol in presence of heat and air degrades into five organic acids namely: Glycolic Acid, Glyoxalic Acid, Formic Acid, Carbonic Acid & Oxalic Acid. Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system.

Propylene glycol corrosion inhibitor is also available in Pre Inhibited Propylene Glycol and normal Propylene Glycol

Glycol turning Red. What does it indicate?
Due to immense corrosion in system, the rust in the system metal makes the glycol turn red in colour. At this point the glycol is fouled with iron contaminants which increase the glycol degradation rate. It is important to add corrosion inhibitor to the glycol system to avoid such degradation of glycol.

Application:
Propylene Glycol System (PG)

Major Benefits:
  • No loss to metal surface after treatment
  • Excellent heat transferability and flow rate
  • Long and extended life of glycol without fouling
  • Avoids leaks in heat exchangers such as PHEs
  • Maintains the anti-freezing properties of glycol

  • Does not form sludge, as in case of other mere pH buffers used in glycol

H2S – A Silent Ultimatum to Oilfields

H 2 S Scavenger Chemical – Introduction The world has witnessed a substantial increase in E&P of crude oil to meet the need for globalization, leading to drilling of ‘deemed undesirable’ sites, owing to the presence of higher concentration of acidic gases like hydrogen sulphide, carbon dioxide, etc. These hazardous gases require proper measures before disposal or scavenging. Of these, Hydrogen sulphide/ H 2 S is the most threatening one, especially in confined or ill ventilated places. The characteristic rotten egg smell makes H 2 S recognition easy even at lower concentrations. Hydrogen Sulphide is toxic, acidic and extremely corrosive at higher concentrations. Heavier than air, it is found more near base level of the working sites. Then comes its inflammability, which may cause explosive reaction with air molecules. With peroxides, ammonia and other oxidizing chemicals, H 2 S often goes through combustible reactions, ...

Acid Corrosion Inhibitor – Chemtex Speciality Limited

  Acid Corrosion Inhibitors are the most important inhibitor of any operation, preventing the impact of corrosion on exposed metal, tubular, downhole equipment, and surfaces and maximizing longevity, minimizing the operational cost. Corrosion is the chemical interaction with the environment that cause the deterioration of materials and it is unavoidable for all metals. When acids come into contact with metals, they initiate chemical reactions that lead to corrosion. Acid corrosion inhibitors work by forming a protective layer on the metal surface, which acts as a barrier against the corrosive acids. This layer prevents direct contact between the acid and the metal, thus inhibiting the corrosive process. Mechanisms of Acid Corrosion Inhibition Acid corrosion inhibitors work by forming a protective layer on the metal surface, which acts as a barrier against the corrosive acids.
