Conceptual process synthesis (CPS) is an important issue in chemical processing industries. In this paper, the general steps of the life cycle of an acid hydrolysis industrial project are evaluated. Chemical route synthesis, process development (experiments for kinetics and fluid dynamics) and process engineering (definition of basic equipment for economic evaluation) are all investigated. A mathematical model was used to generate the most favorable operating conditions for glucose and furfural production from sugarcane bagasse. The material and energy balances were performed by UNISim (TM) software. The Suspension mass fraction and the thermal energy consumption are key issues to account for the profitable operation of the plant.
