Babu Chemical Engineering Department Birla Institute of Technology and Science (BITS) Pilani333031(Rajasthan) India ________________________________________________________________________ Abstract Biofiltration of off gases containing Volatile Organic Compounds (VOCs) is a reliable and cost effective technology for VOCs removal. As most of the enterprises operate in the periodic conditions, a model is developed based on the transient conditions. In the study, a Linear Driving Force (LDF) model is used which takes into account the adsorption of pollutant in the support phase and the rate of biodegradation. The rate equation is given by the modified three-parameter Monod-type expression. The results are compared with the earlier and experimental data as reported in literature. It is also observed that dispersion coefficient plays a significant role in the removal rate of VOCs.

Simulation Studies on Transient Model for Biofilter operated in Periodic Mode
Biofiltration of off-gases containing Volatile Organic Compounds (VOCs) is a reliable and cost effective technology for VOCs removal. Due to many inherent advantages, most of the industries operate biofilters under the periodic conditions (highly transient). Taking the importance of such operation into account, a model is developed based on the transient conditions. In this study, a Linear Driv...

متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
