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

This human generation is going through some tough patches related to natural resources’ depletion, Water being an important one of them. The adversity has started to grow mainly in rain fed areas where nowadays due to uncertainty of sufficient rainfall, the demand for clean water is rapidly increasing and its availability for coming time is declining even faster. The gruesome fact is that the agriculture sector is on a verge of setback, reason being its consumption of most of the available potable water and the current irrigation practices are unable to even cater to the present requirement due to dissimilar landscapes of the sub-continent and their varied soil textures. These areas still follow the ancient techniques which not only lower the effective use of water but also decrease the use of available water for crops. Scarcity of water leads to drought, financial loss and other undesirable frailties like irregular price upsurge, lower productivity, increase in agro ruins etc

Optimal use of machines is directly proportional to its engine performance. What an engine does is it converts the supplied energy into its mechanical form, driving the machine to work. Engines require one-third of total heat that is generated during conversion and the rest of the heat is needed to be evacuated from the combustion chamber which would otherwise lead to engine failure. Earlier, water was preferred as an ideal coolant for quite a period of time but the problem started to arise when the temperature would become extremely high or low, to be precise temperature more than 100 ° C and below 0°C. To get rid of this problem, coolants were formulated. Coolants are categorized chemicals that increases the boiling point of the fluid and decreases the freezing point of the fluid to make it suitable for use in extreme heat and freezing conditions. Coolants are a proportionate mixture of antifreeze and solvent, mainly glycol and water. Ideally utilized as a preventive in
