Corrosion in Chemical and Fertilizer Industries

Any country’s economy and its development primarily depend on its infrastructure apart from existing natural resources in that region. The infrastructure mainly refers to irrigation system, buildings, roads, bridges, airports, transport, education and industries located there. Here it is noteworthy that all these mentioned infrastructures will be corrosion affective which may undergo degradation and deterioration processes. Corrosion is an unavoidable problem that mainly impacts industrial environment. Anthropogenic activity worldwide leads to enhancement of atmospheric pollution which indirectly accelerates corrosion in the form of rust, water pollution. Major industries in any country relate to chemical and fertilizers. India is country with dense population and developing industrially at vast rate. Chemical industry includes companies producing industrial chemicals in which raw materials like water, air, oil, natural gas, minerals and metals converted into seventy thousand products of different type. Indian statistics for the year 2018-19 indicate a production of major petrochemicals and chemicals at 27,847 MT whereas 27,735 MT during 2017-18. In this chapter, we mainly focus on corrosion related to chemical and fertilizer industries, impact of corrosion on their efficiency, corrosion controlling methods and their interrelated phenomena if any.
