Shell-and-tube heat exchanger optimization - impact of problem formulation and cost function
The design optimization of shell-and-tube heat exchangers (STHEs) is studied.Impact of using standard lengths and shell diameters is investigated, and two types of cost function are compared: a simple area-based correlation ...
Characterization of residual biomasses from the coffee production chain and assessment the potential for energy purposes
Chemical quantitative characterization of biomass is relevant for waste to energy recovery technologies. In the present work, selected agroindustry solid residues from coffee crops – parchment and coffee shrub, i.e., stem, ...
Production and characterization of coffee-pine wood residue briquettes as an alternative fuel for local firing systems in Brazil
In this work, the production viability, physical, chemical and mechanical properties of briquettes produced from mixtures of coffee shrub residues and pinewood, were evaluated. The densification was carried out under ...
Hydrothermal carbonization of lignocellulosic agro-forest based biomass residues
To increase the understanding of hydrothermal carbonization (HTC) of lignocellulosic biomass residues, four feedstocks: giant bamboo, coffee wood, eucalyptus, and coffee parchment, were studied. The effect of operating ...
