Biodiesel, mainly produced from soybean, is an alternative to replace fossil fuels and to decrease the Brazilian external dependence on petrochemical diesel. However, soybean represents almost 85% of biodiesel production costs and government subsidie

This article addresses the globally optimal design of kettle vaporizers. Established procedures are heuristics-based trial and verification as well as optimization-based that do not guarantee global optimality. The proposed optimization formulation a

Fouling is a major problem in the operation of heat exchangers, resulting in increased capital, operational, and maintenance costs. Shell-and-tube heat exchangers are traditionally designed using fixed values of fouling resistances, ignoring that fou

Recirculating cooling water systems are used to absorb heat in the heat exchanger network, usually operating in a parallel configuration and returning water to the cooling tower with a higher temperature. This configuration receives the fresh cooling

In this article, the water source diagram (WSD) ( Gomes et al., 2007 ) is extended to the design of water networks involving both fixed flowrate and fixed contaminant load, as well as water loss/gain operations. The algorithm targets minimum external

The use of water in industrial processes has become an important issue over the last 20 years, and then the optimization of water reuse considering multiple contaminants has gained great attention. This paper presents a new approach for the algorithm
