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,

Industrial sectors like Automobiles, Manufacturing, Oilfields, and Processing facilities have huge involvement of metals and the most crucial problem they face is of corrosion. Heavy Industry metals are prone to the attacks of corrosive substances like acids, bases, oxidizing agents, caustic effects, etc., which react with the metal electrons, decreasing its metallic property and resulting in total structural damage. The financial loss caused due to corrosion per year is estimated in the range of thousands of crores and even causing threat to environmental balance. Before further elaboration, let us understand what acidic corrosion actually is and how does it affect metallic attributes? Corrosion is referred to as the deterioration of materials by chemical interaction with the corrosive agents. A common phenomenon observed in the industrial areas, Corrosion complicates the overall working and operations depending upon

Cooling process of automobiles is an important technology as it is directly or indirectly affecting the engine's performance, fuel economy, vehicle aerodynamics, passenger comfort and maintenance, and life span of other components in vehicles, etc. On account of high heat of dissipation, large radiators are now commonly found which finally results into supplementary rise in viscosity and boost the fuel consumption. Therefore, coolant serves as a crucial part of engine's system which helps to cope up with all these challenges faced by the heavy automobile industries. Coolant serves to be an important part of automobiles engine system by providing protection to the engines from freezing and to the other parts as well as components of the vehicles against corrosion. It helps to sustain the overall heat balance by effectively discarding heat energy. Thus, coolant aids in ensuring an effective performance of the engine in the near future. Generally, a good coolant m

In industrial sectors, extensive usage of metals or metal parts, render them susceptible to the formation of rust or tends to get damaged due to scaling. To lend protection to these metals against issues like scaling and rusting, acidic treatment is executed on the surfaces of the metals. Metal parts get dipped in acid baths for removing of rust and scale but this acid treatment is the root for another main concern of the industries. Acidic substances always have the tendency to abrade metals even after the removal of scale or rust. Acid inhibitors are administered in acid pickling baths for the prevention of loss of base metal after proper pickling.   It also  helps in extending the life of acid baths. Using of inhibitor in acid solution aids in limiting the acid attack on base metal, therefore from minimum amount of base metal loss savings can be obtained. A potent acid inhibitor helps in alleviating acid attack on the base metal once the scale has been removed, lending protec

Industries dealing in glycol are known to have metals as system materials.Glycol is known to degrade with air & water into five main organic acids.These acids are better known as 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. Chemtex’s MEG Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. It treats the surfaces of the metal making them less susceptible to corrosion. 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. Dosage : The amount of Corrosion Inhibitor required to inhibit corrosion depends on the type of system, application, brine concentration and plant operating conditions. The spec

Diesel Engine radiators are made up of metals.These metals can get aggravated with corrosion from time to time.This type of corrosion cam mainly happen because of methanol as well of oxygen which gets introduced with it. Chemtex manufactures methanol brine corrosion inhibitor which helps to prevent this type of corrosion single handedly.It is also effective against hydrogen sulfide (H2S) and Carbon dioxide (CO2) corrosion. Hydrogen sulfide reacts directly with iron to form iron sulfide, the reaction is:- H2S + Fe -> FeS + H2 Secondly, carbon dioxide dissolves in water to form H2CO3 which reacts directly with iron to form FeCO3, the reaction is:- H2CO3 + Fe -> FeCO3 + H2 The types of corrosion experienced by the metal in Methanol Brine System are Pitting corrosion- caused due to formation of acids in presence of Carbon dioxide and Oxidation corrosion- caused due to reaction of metal with oxygen or air. Chemtex methanol corrosion inhibitor helps us to p

In chemical industries metals play a very important role.Such metal surfaces are known to get corroded from time-to-time.These corrosive action is mainly due to the reaction of acids during pickling,pH adjustment & cleaning applications. Chemtex manufactures sulfuric acid corrosion inhibitors(Rodine) which contains surfectants which are stable at high temperatures as well. The inhibitor improves rinsability, aids in attaining maximum efficiency on cleanliness and pickled work. Application : Multiple applications for metal surface treatment, cleaning, pickling, pH adjustment or alkalinity reducer for versatile industries Major Benefits:- ·         It provides support for metal protection. ·         Wetting properties for effective cleaning.             Contact Us Chemtex Speciality Limited Regd.
