Drying of sugar cane bagasse was theoretically and experimentally studied in a cyclone. The experiments were carried out using hot air as drying agent. The influence of the cyclone conical part was studied. It was shown that the conical part has a great influence on the particle residence time and, consequently, on moisture *** results were alike industrial ones. CFX 4.4坰 from AEA Technology was used to simulate some experiments. Simulated and experimental results were close and showed that the presented model leads to a good prediction.

The aim of this study is to assess the possibility of increasing ethanol production by introducing the bagasse hydrolysis process into conventional *** were performed for mass and energy balances using Aspen Plus?*** was assumed that sugarcane trash and lignin cake—hydrolysis process residues—are available as supplementary *** cases were evaluated,including:(a)conventional ethanol distillery,(b)conventional plant combined with a hydrolysis process without heat integration,with different solid contents in the hydrolysis reactor,and(c)conventional plant combined with the hydrolysis process applying heat integration by pinch *** highest ethanol yield was achieved in the case of heat integration and concentration of cellulose hydrolysate by the membrane system with a solid content of 5%in the hydrolysis *** represents an increase of 22%over conventional distilleries currently found in the industry.
