The water-gas shift reaction is an important industrialreaction used to generate useful hydrogen gas as a fuelor a precursor to other chemicals:CO +HO(8) 2 (g)=H + CO2 (g)2(g)Since it is a reversible reaction, much attention has beenfocused on optimizing the feed ratio and temperature toobtain desirable conversions. In one production line, acatalytic reactor is charged with 359 mol/h of a gaseousfeed with a steam to CO molar ratio of 2.19. At thereaction temperature of 294°C, the limiting reactantconversion was found to be 92.56%. What is thehydrogen gas concentration at the reactor outlet?Type your answer as a mole fraction, 4 decimal places.

Acetylene (C2H2) may be formed from methane (CH4) by pyrolyzing-decomposing at high temperature according to the reaction: 2CH4 (g) → C2H2 (g) + 3H2 (g) In a commercial reactor system, the methane is supplied as a liquid at 25°C to a heater where it is heated and vapourised leaving as a vapour at 650°C. The vapour then passes to the catalytic reactor in which a conversion of 40% is achieved. It may be assumed that there are no other reactions, that operation is at a pressure of one atmosphere and that the stream leaving the reactor is all in the vapour state. With a complete block diagram of the process, determine the heat transfer rate (kW) required to the reactor if it is operated isothermally. Evaluate on the value of the heat transfer rate obtained from your calculation.

Methanol (CH3OH) and its derivative products are used as base materials in acrylic plastic, synthetic fabrics, adhesives, paints and as chemical agent in pharmaceuticals and agrichemicals. In petrochemical industry, one promising pathway to produce methanol is from conversion of syngas to methanol via hydrogenation of carbon dioxide and carbon monoxide. The reaction of this process is given as follows, CO + 2H2 → CH3OH (1) CO2 + H2 → CO + H20 (2) Suppose 1000 kmol/hr of syngas with molar composition of 22% CO2, 6.7% CO, 65% H2, 4.1% H20, 1.1% CH4 and 1.1% N2 is used as fresh feed. (a) Draw and label a complete process flow diagram of this process. (b) Calculate the amount of unreacted CO2 if given single pass conversion of CO2 is 14.2%. (c) Calculate the extent of reaction for the side reaction (2) and the amount of water produced. (d) If the selectivity of methanol to water is 92.1%, calculate the amount of methanol produced. (e) Determine mole fraction of CH3OH, CO2, CO, H2, H2O, CH4…

Alumina from bauxite separation stage calculations A crucial step in the production of aluminum from bauxite ore is the separation of alumina from the remaining mineral impurities in the ore. In the Bayer process this is accomplished by treating bauxite with aqueous NaOH to produce NaAIO2 (alumina). NaOH(aq) + Al(OH)3(s) → NaAIO2(aq) + 2H2O(1) Since NaAIO2 is water soluble while the residual mineral constituents of bauxite are not, a separation can be achieved by allowing the minerals to settle out and decanting the aqueous solution of NAAIO2 and unreacted NaOH. In order to further recover any NAAIO2 entrained in the settled mineral solids, this "mud" is repeatedly washed with water and allowed to settle, and the wash water is decanted. The figure below shows one stage of this washing-settling process. Wash water Slurry - Open to air Mixer/Wash tank Setling tank Decanted solution System boundary Washed mud In this stage, a feed slurry consisting of 10 wt% solids, 11 wt% NaOH, 16 wt%…
Acetic acid is esterified in the liquid phase with ethanol at 100 degrees * C and atmospheric pressure to produce ethyl acetate and water according to the reaction: CH 3 COOH(l)+C 2 H 5 OH(l) CH 3 COOC 2 H 5 (l)+H 2 O(l) If initially there is one mole each of acetic acid and ethanol, estimate the mole fraction of ethyl acetate in the reacting mixture at equilibrium.
Cyclohexanol is a highly desired chemical precursor for the production of nylon (billions of kilograms of cyclohexanol are produced annually!). Industrially, cyclohexanol can be formed by the oxidation of cyclohexane over cobalt catalysts. You have a vapor mixture of 50 mol.% cyclohexane and 50 mol.% cyclohexanol. You want to cool and condense your vapor mixture to form a vapor product and a liquid product. a. This problem contains a vapor-liquid system. Using the Gibbs phase rule, determine the number of degrees of freedom in a vapor-liquid equilibrium. b. Your vapor mixture fills a drum that is 300 L in volume. At atmospheric pressure and at 200°C, how many moles of vapor do you have? *c. You decide to feed your vapor mixture to the condenser at 5 mol/s. You measure your vapor product and see that it comes out at 760 mmHg and 75 mol.% cyclohexane. Using Raoult’s law and Antoine’s Equation, determine your outlet temperature. *d.
