The water-gas shift reaction is animportant industrial reaction used togenerate useful hydrogen gas as a fuel or aprecursor to other chemicals:CO + H₂O(8)2 (8)=H2(g)+ CO2(g)Since it is a reversible reaction, muchattention has been focused on optimizingthe feed ratio and temperature to obtaindesirable conversions. In one productionline, a catalytic reactor is charged with 349mol/h of a gaseous feed with a steam toCO molar ratio of 1.86. At the reactiontemperature of 272°C, the limiting reactantconversion was found to be 88.98%. Howmuch hydrogen gas was produced?Type your answer in mol/h, 2 decimal.nlaces.places.

One of the ways that benzene is produced on a large scale is the hydrodealkylation of toluene. C,H,CH; + H, C,H, + CH4 A stream of toluene is mixed with a recycle stream and enters a reactor along with a stream of pure hydrogen. The reaction products at 550 °C enter a condenser, where they are cooled to 41.0 °C. A vapor stream containing Y5CH, = 0.600 mol CH,/mol leaves the process, and a liquid stream containing x66 = 0.810 mol benzene/mol and x6 = 0.190 mol toluene/mol enters a distillation column. The distillate of the column leaves the process at n7 = 668.0 mol/h and contains y7h = 0.9000 mol benzene/mol and y7 = 0.1000 mol toluene/mol. The bottoms of the column contains X8b = 0.250 mol benzene/mol and xgt = 0.750 mol toluene/mol and is recycled back to the fresh feed. Hydrogen is fed into the process at ni = 1183 mol H,/h. This process is carried out at 760 mmHg. A n, mol/h mol H/mol YSH2 YSCH, mol CH_/mol Ysh mol b/mol Ys mol t/mol n̟ mol/h n, mol/h Condenser Улн, тol H/mol Усн,…
1,3,5 trimethylbenzene may be reacted with hydrogen over a catalyst to form meta- xylene, which is a valuable product at $1.35/kg. However, meta-xylene may also react with hydrogen to form toluene, which is much less valuable at $0.50/kg. Methane is a side product of both reactions, and it gets recycled elsewhere in the plant. 1 kg of catalyst is degraded for each 200 kg of toluene produced, and it must be disposed of in a toxic waste landfill at a cost of $25/kg. It is proposed to alter the conditions of the reactor such that the selectivity of the reaction is increased from 0.8 (the current selectivity) to 0.9 (the proposed selectivity). Calculate the amount of money gained (in dollars) by making this change to the process, for each 100 kg of 1,3,5 trimethylbenzene reacted.

In the operation of a synthetic ammonia plant, a 1:3 nitrogen-hydrogen mixture is fed to the converter resulting in a 37% conversion to ammonia. The ammonia formed is separated by condensation, and the unconverted gases are recycled to the reactor. The initial nitrogen-hydrogen mixture contains 0.3part of argon to 100 parts of N2-H2 mixture. The toleration limit of argon entering the reactor is assumed to be 7 parts to 100 parts of N2 and H2 by volume. Estimate the fraction of recycle that must be continually purged.
3. Nitrobenzene is an intermediate used to produce phenylamine or aniline. Its application extends to the production of lubricating oils used in motors and machinery. Nitrobenzene is produced by the reaction of benzene and nitric acid as shown. C6H6 + HNO3 C6H5NO2 + H₂O 75 kmoles of benzene and 200 kmoles of mixed acid are fed into a reactor. The mixed acid is composed of 50.2 %mol H₂SO4, 42.5 %mol HNO3, and the rest is water. All the benzene is completely isolated in the separator is fed back to the reactor.

Ethylene is the largest single chemical commodity in the world. It is the precursor for polyethylene, the most common form of plastic. One method for producing ethylene is to "crack" ethane using high temperature steam. C2H6→C2H4+H2 C 2 H 6 → C 2 H 4 + H 2 Successful cracking requires that the ethane reach a temperature of 800-900 [C]. Assume that pure ethane flows into a cracking unit at 75 [C] and that the fractional conversion of ethane in the unit is 80%, and that the outlet temperature is 800 [C]. How much heat is required to produce 1,000 [kg] of ethylene? Compare both the heat of reaction and heat of formation method. For this reaction, Δh∘r=137kJ/(molC2H4) Δ h r ∘ = 137 k J / ( m o l C 2 H 4 ) .
