Methanol vapor is burned with excess air in a catalytic combustion chamber. Liquid methanol initially at 25°C is vaporized at 1.1 atm and heated to 100°C; the vapor is mixed with air that has been preheated to 100°C, and the combined stream is fed to the reactor at 100°C and 1 atm. The reactor effluent emerges at 300°C and 1 atm. Analysis of the product gas yields a dry-basis composition of 4.8% CO2, 14.3% O2, and 80.9% N2.
- Calculate the percentage excess air supplied and the dew point of the product gas.

- A hydrocarbon stream composed of 40 mol% n-butane and 60 mol% n-octane is fed at 100 kmol/h to a flash vessel operating at 5 bar and 145°C. The liquid outlet stream of the flash vessel is then sent to a distillation column with a partial condenser to further separate the components. 90% of the butane in the feed to the column is recovered in the overhead vapor product (distillate), along with small amounts of octane. The bottoms product contains octane which accounts for 75% of the octane in the fresh hydrocarbon feed (to the flash vessel). The condenser and reboiler operating temperatures are 136.7°C and 165.7°C, respectively. Determine the compositions of the liquid outlet stream of the condenser and the vapor outlet stream of the reboiler.arrow_forwardThe synthesis of methanol from carbon monoxide and hydrogen is carried out in a continuous vapor-phase reactor at 5.00 atm absolute.

- Q4/in a two stage process, acetic acid (A)is extracted from water (W) into hexanol (H) in a liquid-liquid extraction vessel and the extract is subsequently separated by distillation. Assume that water is completely insoluble in hexanol. A mixture of 18wt% acetic acid and the balance water is feed to liquid-liquid extraction vessel. Pure hexanol is feed to the column to extracted the acetic acid. The water-rich stream leaving the vessel is 99.5wt% water and the balance acetic acid. The hexanol-rich extract from the vessel is feed to a distillation column. The composition of the distillate is 96wt% acetic acid and the balance hexanol. The bottom stream contains 97.2wt% hexanol and recovers 95% of the hexanol feed to the liquid-liquid extraction vessel.

The mixture enters a distillation column that creates two streams. A top stream exits that contains 70 mole% methanol and balance with water. The bottom stream, which is 70 moles, enters a second distillation column. A top stream exits the second column as a 50% methanol and 50% water.

- Methanol (CH3OH) is produced in the reaction of carbon dioxide and hydrogen via the reaction and process given below: CO2+3H2→CH3OH+H2O The fresh feed to the process contains hydrogen, carbon dioxide, and 0.400 mol% inerts (I). The reactor effluent passes through a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The unreacted reactants and inerts are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts. The single-pass conversion of hydrogen is 46.71%.

Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake.

The HF is then dissolved in water to form hydrofluoric acid. A source of calcium fluoride is fluorite ore containing 96 wt% CaF2 and 4% SiO2. In a typical hydrofluoric acid manufacturing process, fluorite ore is reacted with 93 wt% aqueous sulfuric acid, supplied 15% in excess of the stoichiometric amount.
