A toxic pollutant with an initial concentration 598.08 is being treated in a batch reactor. Unfortunately, we were unable to as certain whether the substance degrades via first order or second order reaction. If the goal is to reduce the concentration by 95%, determine the number of days............... for 1 order deacy and the number of days ...............for 2nd order decay to reach the target effluent concentration: The reaction rate constant for the first and second order reaction are 0.5 d(-1) and 0.5x10(-3) mg(-1)d(-1) respectively.

A waste stream flows at 2,000 liters/day with a concentration of 60 mg/l of hazardous chemicalA. The chemical undergoes a first-order decay reaction with k = 0.01/sec. Complete performanceanalyses of the three common ideal chemical reactors to determine the effluent concentration ofchemical A for the following conditions:1. CSTR, V = 500 liters2. PFR, V = 14 liters3. Batch Reactor, V = 500 liters (i.e., 4 batches of waste processed per day to handle thetotal daily volume of 2,000 liters) with a reaction time τ = 10 min.Compare and contrast the performance of each reactor type.
You are studying a reactor that receives a particular reactive contaminant which follows a zero order reaction process (ie. the reaction rate is independent of the concentration of the contaminant). If you assume plug flow, a cross sectional average velocity of 10 cm/sec, and a zero order reaction rate of 0.5 mg/l min, how long should my reactor be such thatthe concentration is reduced by from 10 mg/L to 1 mg/L? (hint: do a mass balance for the system).
Environmental Engineering: Water Treatment Please consider each of the following points: a. Determine the required residence time for each reactor of 3 equal volume CSTRs in series given a zero-order reaction with a reaction rate constant, k = -5 mg/L hr. The influent concentration is 125 mg/L and 95% conversion is required across the three-reactor system. What is the total reactor system residence time? b. Determine the required residence time for a single CSTR given the same conditions. c. Determine the required residence time for a PFR given the same conditions. d. Why are all three residence time the same?
(a) Prove that for a first order decay reaction (k1= 2 days-1) taking place in reactors of identical size at steady state, it does not matter if you use a CMFR followed by a PFR or a PFR followed by a CMFR (i.e. show that the final treated effluent concentration, in mg/L, is approx. the same in each scenario). Assume the volume of each reactor is 15 L and the reactors in series will be used to treat a wastewater containing 5 mg/L of contaminant “C” at a flowrate of 10 L/day. (b) Does this remain true if a second order decay reaction was taking place? If not, which sequence of reactors is more efficient (i.e. removes more of the contaminant)? Assume the same reactor volumes, flow rate and contaminant concentration as in part (a), and k2 = 2 Lmg-1day-1 . You must show your derivation of the expression for a PFR with 2nd order decay.

As a plant maintenance engineer, you are required to purchase a 3,000 L tank of liquid butane to heat a maintenance building during the winter. You are concerned about the tank rupture and the possibility of a vapour cloud explosion of all the butane. How far (in metres) must the tank be from the maintenance building to ensure that it will receive only partial demolition in the event of an explosion? The specific gravity of liquid butane is 0.6, and the energy of explosion for butane is 510 kcal/gm-mol. Assume the explosion efficiency is 10 % in this case.
