Question

Unit ops

A tank has the following dimensions: depth =2m, width -2 m, length = 12 m. it can be fed at one end. such that the reactor behaves like a plug flow reactor (PFR), or the feed can be distributed and the tank mixed so it behaves like a completely-mixed, stirred tank reactor (CSTR). A waste stream with flow rate of 100 m3/hr contains a chemical that has a first-order decay reaction of 0.1 hour1. This waste stream, which has a concentration of the chemical of approximately 50 mg/L, is to be treated in the tank.Estimate the effluent concentration (mg/L) of the chemical under both of the proposed flow regimes.Briefly explain why the two values are not the same and list one potential advantage for each of the two flow regimes (PFR and CSTR) for treating this waste stream
