Análise técnico-econômica do processo de produção do álcool isopropílico

Abstract

Isopropyl alcohol is one of the most widely used solvents in the world and with a growing global market. With the increase in its importance, there is also a need to analyze existing production routes of the compost in order to optimize them, in addition to finding alternative ways to increase its efficiency and study its economic viability. From an existing plant, the route used is described and some improvements suggested. In addition, CAPEX, OPEX, NPV and payback economic parameters are studied using the CAPCOST spreadsheet to determine the economic viability of the plant. After the economic analysis, a CAPEX of $30,910,000.00, an OPEX of $203,871,545.00, an NPV of $23,020,000.00 and a payback of 2.7 years are obtained. Therefore, it is concluded that the plant is economically viable. Examining two proposals for energy optimization of the original process, it appears that the plant with water in excess with the reactive distillation tower has significant economic advantages over the original plant, increasing the economic viability of the overall IPA production process.
