Coolant Corrosion Inhibitor



Antifreeze helps prevent liquid from freezing in sub-zero temperatures, and preventing boil-outs above the designated boiling point of the same so that it doesn’t evaporate.

 A study confirms three-fifth of all engine problems are coolant-related. For an engine to operate optimally, only one-third of generated heat/ energy is required and the rest is released or transferred. If this transfer does not take place, it would lead to overheating of engine equipment, causing breakdown and/ or failure. Overheating adversely affects the engine's efficiency directly, affecting performance, fuel economy, maintenance, and longevity of vital engine components. Using recommended coolant ensures that the engine runs at an optimum temperature without any heat-related hassles.

 What is coolant to begin with?
Coolant, derived from antifreeze chemicals are commercial grade antifreeze chemicals used in automobiles, DG sets, heavy-duty systems, etc., protecting the engine from getting disintegrated/ damaged at higher temperatures by transferring the excess heat formed.
Generally, coolants used in engines are homogeneous mixture of glycol and water, reason being their flexible thermal properties like high boiling point, low freezing point, stable over a wide range of temperature but …

 … Is coolant enough?
Glycol oxidizes at high temperatures into organic acids: glycolic, glyoxalic, formic, carbonic and oxalic. These are highly corrosive and can be corrosive to the system metal causing problems like pitting, pinhole and stress cracking corrosion. Even the resulting contaminants present in glycol adding more to its rate, degrading the total working system.

 The main problems with this undesirable acidity are:
·         Affects metallic pipelines, which leads to failure of temperature balance owing to heat loss
·         Pitting causes irregular holes, gradually leading to leakage of coolant into the combustion chamber
·         Scale depositions disrupt the heat transfer efficiency of the coolant
To tackle these problems, coolant additives such as corrosion inhibitor chemicals were synthesized.

 Coolant corrosion inhibitor are chemical additives that when added to coolant to protect the internal surfaces from corrosion related adverse effects. These inhibitors made with components of the finest grade not only ensures efficient reduction in mineral scale and sludge deposits but also provides efficient protection to metallic components from corrosion with its unique features like anti-corrosion and system life enhancement.

 Coolant – Inhibitor Technology
·   IAT based: Inorganic Salt additives based coolant
·   OAT based: Organic Acid Technology based coolant
· HOAT based: Hybrid organic acid technology (HOAT) is combination of IAT and OAT technologies

Compatible with heavy duty coolant, comprising of glycol, water and corrosion inhibitors that control irregular pitting, scaling, etc. Heat produced by the engine is absorbed by the coolant which helps in maintaining regulated temperature in the system, transferring excess heat to the appropriate media and the incorporated inhibiting property makes the metallic surface inert against all types of oxidizing reaction of organic acids, ensuring corrosion free heat transfer system.
Coolant Corrosion Inhibitor provides anti-freeze properties, boil over protection, and component protection and meets all the requirements as per industry standards. These are formulated by making use of premium grade chemicals with sophisticated methodologies for anti-corrosion, anti-scaling, and anti- fouling properties.

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.
