Diseño de una planta de valorización de baterías usadas de automóviles.

Abstract

The objective of the proposal is the design of a recovery plant for scrap-type car batteries by developing a modified ISASMELT-ENGITECX process. Junk batteries can affect health and the environment if they are not treated properly, which is why they become a source of pollution. The project plans to be profitable by selling the generated products (metallic lead, recycled polypropylene and sodium sulfate). Through market analysis, it was considered that 25% of all scrap batteries generated in the country can be treated, which is equivalent to 22,500 lead-acid batteries per month. Within the development of the proposal, the BFD, PFD, Layout and P&ID of the scrap battery recovery plant were prepared. Based on the recovery process proposed, it would be possible to recover 88.11% of the initial lead present in the batteries, which is equivalent to 171,151.87 kg of lead per month. Through the economic pre-feasibility evaluation, the profitability of the project was determined. The project proved to be profitable, with a lifetime of 6 years. The project indicates a positive NPV of 6,790,253.51 USD and an IRR of 73%.
