Chapter 1 Overview of Chemical Reaction Engineering 1.1 Municipal waste water treatment plant. Consider a municipal water treatment plant for a small community(Fig.P1. 1). Waste water,32000 m3/day,flows through the treatment plant with a mean residence time of 8 hr, air is bubbled through the tanks, and microbes in the tank attack and break down the organic material (organic waste)+O2 wicrobes CO2+H2O A typical entering feed has a BOD (biological oxygen demand)of 200 mg O?/liter, while the effluent has a megligible BOD.Find the rate of reaction, or decrease in BOD in the treatment tanks. Waste water 32.000 m3/day Waste water Treatment plant Clean water 32,000 m3/day 200 mg O needed/liter Mean residence time t =8 hr Zero O1 needed Figure P1.1 Solution: =18.75mol/(m3 ·day)=2. 17×10?mol/(m3 · s) 1.2 Coal burning electrical power station.Large central power stations(about 1000 MW electrical) using fluiding bed combustors may be built some day (see Fig.P1.2),These giants would be fed 240 tons of coal/hr(90% C,10%H2),50% of which would burn within the battery of primary fluidized beds, the other 50% elsewhere in the system.One suggested design would use a battery of 10 fluidized beds, each 20 m long,4 m wide, and containing solids to a depth of 1 m.Find the rate of reaction within the beds, based on the Fluidized bed 10 mx4mx1m 240 90% ton/hr C.10%H 50% of the feed burns in these 10
