IUS: Indústria de ureia e saneantes

Abstract

The use of sanitizing products, whether in households or industrial cleaning, has shown a growth rate over the past years, leading to a projection for the coming decades higher than the currently produced amount. In this context, this work also presents the IUS project, an industry for the production of urea and sanitizers, using this component in its formulation as a wetting and thickening agent, ensuring better consistency and product quality. Urea can also help reduce corrosion and enhance the effectiveness of detergents. Additionally, the company will use urea as part of a sustainable approach, as it is a natural byproduct of the decomposition of organic compounds and can be produced on a large scale. With the addition of urea to the formulation, IUS emerges to offer a high-quality detergent to its customers. Another important factor is that the company will market granulated urea in the fertilizer market, meeting the growing demand in the agricultural industry. To achieve this, IUS, located in the city of Nova Ponte (MG), aims to supply the market with 72.000 tons/year of both products, namely detergent and urea, representing 5% of the estimated national demand for the year 2050. To achieve this, 50.107 tons/year of CO2 and 38.780 tons/year of NH3 will be required to ensure the necessary production of urea with an overall yield of 76%, generating 65.8 tons/year of waste (oxygen, nitrogen, and water vapor), 20,5 tons/year of water, and an energy consumption of 6,7 MW. However, with the use of energy integration, the industry will be self-sustainable in terms of hot utilities. Focused on cost reduction, the IUS production process includes recycle and energy reuse systems, along with an industrial layout aimed at reducing process downtime and decreasing expenses on pneumatic and centrifugal transport. These conditions ensure a sufficient net profit for the initial investments needed for construction and installation to be paid off in 10 years. During this time, the return on invested capital is guaranteed, and the company will have an internal rate of return higher than the minimum attractive rate for ventures in this sector, driving and fostering the development of this project.
