2. A horizontal spray chamber with recirculated water is used for adiabutic humidification and cooling of air. The chamber has cross- section of 3m' with an air rate of 5 m' is at dry bulb temperature of 60 "C and absolute humidity of 0.017 kg water / kg dry air, the air is cooled and humidified to a dry bulb temperature of 34" C and leaves at 80% RH. For the system volumetric mass transfer coefficient may be taken as 1.12 kg /m'. s(AY).the Density of the air is 1.113 kg/m'. Determine the Length of chamber for the requirements. (Ans 4.59 m)

Hazard Analysis and Design in Chemical Engineering

Hazard is the intrinsic property of a material or process which harms the people, buildings, or environment. Health, safety, hazard, risk assessment, loss prevention, and environmental consideration play an important role while designing a chemical processing plant. Hazard is often confused with risk. Risk measures the magnitude of loss and injury of likelihood incidents or the consequence and frequency of incidents.
