VOCs are one of the main sources of photochemical reaction in the atmosphere leading to various environmental hazards. Thermal oxidation is the only viable method for controlling toxic and other certain harmful air pollutants. Regenerative thermal oxidation incorporating two regenerators is quite effective in VOC incineration process. In the present work a mathematical model has been studied using the computer code developed in Fortran language. Present work deals with study of various operating parameters like particle diameter, bed cross sectional area and cycle time for different xylene concentrations. Temperature distribution in the bed for different particle diameters and bed cross sectional area is analysed. Effect of particle diameter and bed cross sectional area on regenerator bed length is also studied. Bed length is optimised in each case for attaining operative oxidation temperature of 8600C. Effect of cycle time on average exit temperature of hot gas as well as thermal heat recovery (TER) is also discussed. It is observed that with increase in particle diameter regenerator bed length increases and with increase in bed cross sectional area it decreases. TER remains constant with increase in particle diameter as well as bed cross sectional area. Increasein cycle timeincreases average exit temperature of hot gas which in turn reduces TER. TER remains constant up to cycle time of 600s but after that it starts reducing. The increase in xylene concentration after 1200 ppm significantly reduces TER as well as bed length for corresponding particle diameters and bed cross sectional areas.ennullThesis
