In the hydrocarbon processing industry (HPI), the manufacture of ammonia and urea holds a prominent role. These petrochemicals have sustained the growth of agricultural production with new technologies and processes. This industry uses many different feedstocks such as coal, liquid petroleum, natural gas, and refinery residues. These feeds are processed under extreme pressure and temperatures in a highly corrosive environment. Despite these processing challenges, large-scale fertilizer plants are built worldwide to meet the growing fertilizer demand. A major factor contributing to this achievement is the industry's succe
