The mechanical disintegration can be described as follows the wet chitins are suspended in water at 0.1-0.3%. Several drops of acetic acid, a dilute hydrochloric acid solution, or a dilute NaOH solution are added to the chitin slurries to adjust their pH values from 3 to 8. Ultrasonication is appfied to the slurries (15 mF each) for 2 min using an ultrasonic homogenizer at 19.5 kHz and 300 W output power (7 mm probe tip diameter). The temperature increase is kept below 5 °C during the ultrasonication [37]. 

For each run, the experimental and calculate values of outputs (flow rates, concentrations), the vapour composition and liquid temperature profiles are compared a good agreement is systematically observed without need of parameter adjustment. For illustration, one run is detailed. The liquid feed is water and acid acetic (0.76 mass) mixture with a flow of 4.34 kg/hr, and the vapour feed is pure methanol with a flow of...
