Pulping Of Vetiver Grass With NH4OH-KOH-AQ Mixtures
Abstrak
The detail analysis of the heat and mass transfer between the droplet containing
suspended solids and the drying gas was carried out numerically. The temperature and
moisture distributions within the slurry droplet were calculated during the first and
second drying phases. The parametric study revealed that the droplet drying time
decreases with increasing the drying gas temperature and decreasing the droplet
diameter.
