Integration of torrefaction and CHP plant: Operational and economic analysis
(Elsevier, 2016-12-01)
Biomass torrefaction is a pre-treatment technology with high potential to convert biomass into a valuable commodity. The heat integration of torrefaction and combined heat and power (CHP) plant was investigated in previous ...
Production and characterization of coffee-pine wood residue briquettes as an alternative fuel for local firing systems in Brazil
(Elsevier, 2019-02-26)
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 ...
Biomass-based carbon capture and utilization in kraft pulp mills
(Springer Netherlands, 2019-01-04)
Corporate image, European Emission Trading System and Environmental Regulations, encourage pulp industry to reduce carbon dioxide (CO2) emissions. Kraft pulp mills produce CO2 mainly in combustion processes. The largest ...
Characterization of residual biomasses from the coffee production chain and assessment the potential for energy purposes
(Elsevier, 2018-11-19)
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, ...
Effect of heat integration method and torrefaction temperature on the performance of an integrated CHP-torrefaction plant
(Elsevier, 2015-07-01)
An important factor for industrial-scale implementation of torrefaction – a thermal pre-treatment technology that enhances the fuel characteristics of biomass – is the requirement for a low-cost source of heat energy. ...
Towards large, fossil free mills with integrated biorefineries : trends in modern pulp mills
(ABTCP, 2018-10-23)
Global economics require ever larger pulp mills with increased energy efficiency. Paris agreement means pulp and paper mills need to significantly reduce fossil fuel based carbon dioxide emissions. World markets are turning ...
Shell-and-tube heat exchanger optimization - impact of problem formulation and cost function
(HEFAT, 2019-07-22)
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 ...
Pre-treatment of coniferous biomass via hydrothermal carbonization and torrefaction: mass and energy yields
(Benet Ltd., 2015-09)
Fuel properties of woody biomass could be significantly improved with several pre-treatment technologies. This paper presents the results of experimental comparison of hydrothermal carbonization and torrefaction processes ...
Hydrothermal carbonization of coniferous biomass: Effect of process parameters on mass and energy yields
(Elsevier, 2015-05)
Hydrothermal carbonization of biomass presents a promising way to improve fuel characteristics of biomass without preliminary drying. In this process, feedstock is subjected to heating with water at temperatures between ...
