An ethanol (A) water (B) solution in the form of stagnant film 2.0 mm thick at 293 K is in contact at one surface with an organic solvent in which ethanol is soluble and water is insoluble. Take NB=0. At point 1 the concentration of ethanol is 16.8 wt% and solution density is r1 =972.8 kg/m3. At point 2, the concentration of ethanol is 6.8 wt% and r2 = 988.1 kg/m3. The diffusivity of ethanol is 0.740x 10-9 m2/s. Calculate the steady state flux NA

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.
