A gas stream containing 40.0 mole% hydrogen, 35.0% carbon monoxide, 20.0% carbon dioxide, and 5.0% methane is cooled from 1000°C to 10°C at a constant absolute pressure of 35 atm. Gas enters the cooler at 120 m3/min, and upon leaving the cooler, is fed to an absorber where it is contacted with refrigerated liquid methanol that enters the absorber at a molar ?ow rate 1.2 times that of the inlet gas and at — 155°C. Essentially all of the CO2is absorbed, as is 98% of the methane and an inconsequential amount of the other components of the feed gas. The gas leaving the absorber is saturated with methanol at −12°C and is fed to a reactor for further processing.
(a) Calculate the volumetric ?ow rate of methanol entering the absorber (m3/min) and the molar ?ow rate of methanol in the gas leaving the absorber. D0 not assume ideal-gas behavior when doing PVT calculations.
(b) List and explain at least three hazards associated with the system described.
(c) One of the possible uses of the product gas is as a feed to a reactor in which the water-gas shift reaction takes place:

- 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 To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts.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%. What is the recycle-to-fresh feed ratio?arrow_forwardA gaseous fuel containing methane and ethane is burned with excess air. The fuel enters the furnace at 25°C and 1 atm, and the air enters at 200°C and 1 atm. The stack gas leaves the furnace at 800°C and 1 atm and contains 5.32 mole% CO2, 1.60% CO, 7.32% O₂, 12.24% H₂O, and the balance ₂. 1. Calculate the molar percentages of methane and ethane in the fuel gas and the percentage excess air fed to the reactor. 2.

- (5) The emissions from a manufacturing process contain gaseous pollutant that cause odors and fumes. The company plans to incinerate the 5,000 acfm exhaust stream. Estimate the volumetric (standard) flowrate of natural gas fuel required to increase the waste gas stream temperature from the initial 80°F to the required temperature of 2500°F. Energy (enthalpy) is transferred from the fuel to the gas. Neglect any possible heat losses in this process. The average net heating value of natural gas is 850 - 1050 Btu/std-ft. Include a diagram of the scenario.arrow_forwardTo prepare a delicious banana milk on an industrial scale, there is an experimental process that consists of seven unit operations. A stream of banana (whose components are fruit, peel, and moisture) is fed to a peeler, where 99.9% of the peel is removed. This stream should become pulp, so it is mixed with an additive Q to avoid pulp oxidation. This mixture is then sent to an extruder press wherein a stream of a 50:50 mixture of additives Q and R is added. The resulting flow of 30 kg/h has a composition of 2% additive R and 5% additive Q. This flow is then fed to an agitated mixer. To the same mixer is fed a dairy stream of 250 kg/h that contains 70% milk (the rest is water) and a sweet aqueous stream that contains 30% sugar. For each 25 kg/h of dairy flow, 2 kg/h of the sweet flow is fed. The stream that leaves the agitated mixer has 5% fruit and 0.005% peel and enters a series of two thermal processes in which each operation allows 5% of the water and 2% of the milk to evaporate.

A customer has ordered the airplane but requested that its total weight be reduced by 10 percent for fuel saving purposes. An engineer in the design and analysis department has suggested that the weight saving objective can be accomplished by replacing the current aluminum alloy of the floor beams with another one containing 3 wt% Li and 1 wt% Cu. Is this possible? Answer the question by first determining the weight saving that will take place using the Al-Li alloy. Assume weighted averages of density and use the following densities for the mentioned materials: Al = 2.70 g/cm³ Cu = 8.92 g/cm³ Mg = 1.74 g/cm³ Li = 0.53 g/cm³arrow_forward
- Solid calcium (CaF2) reacts with sulfuric acid to form solid calcium sulfate and gaseous hydrogen fluoride. 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. Ninety-five percent of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction 6 HF + SIO2 (aq) – H2SİF6 (9) + 2 H2O (1) The hydrogen fluoride exiting from the reactor is subsequently dissolved in enough water to produce 60 wt% hydrofluoric acid. Calculate the quantity of fluorite ore needed to produce a metric ton of acid.
