Hydrothermal carbonization of coniferous biomass: Effect of process parameters on mass and energy yields
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 ...
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 ...
Integration of torrefaction and CHP plant: Operational and economic analysis
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 ...
Effect of heat integration method and torrefaction temperature on the performance of an integrated CHP-torrefaction plant
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. ...
