A waste gas stream, containing 15 % CO2,5 % H2S, 1.5 % Co, and the balance...
A waste gas stream, containing 15 % CO2,5 % H2S, 1.5 % Co, and the balance is CH4 by mass, is leaving a chemical process. H2S and CO have to be removed from the waste gas stream due to severe environmental concerns. An absorber is installed so that H2S and CO in the waste stream can be removed before being released to the environment. The absorber design placed a maximum flow rate limit of 75 kg/h. Therefore, any feed flow...

Problem 1 An absorber-stripper process is used to remove carbon dioxide (CO2) and hydrogen sulfide (H2S) from a feed (stream 1) consisting of 25% CO2 and 15% H2S in nitrogen. In the absorber, a solvent selectively absorbs hydrogen sulfide and carbon dioxide. The absorber overhead (stream 2) contains only 2% CO, and the balance Nitrogen with no Hys. Ny is insoluble in the solvent. The rich solvent stream leaving the absorber (stream 3) is flashed in a flash separator: the...

Sorry about that.
#8 (20 pts) SO2 is to be removed from a CIL gas stream by contacting the gas with solid adsorbant in an adsorber. The feed gas is 7 mol % SO2 and 93% CH4. The absorber operates at 1 atm and 25°C. The solid adsorbant enters the adsorber essentially free of any SO2, 95% of the SO2 is to be removed from. the gas. An equilibrium X-Y diagram for this system is shown below Find the ratio...

Methanol is synthesized from carbon monoxide and hydrogen (H2) in a catalytic reactor. CO + 2H2 → CH3OH The fresh feed to the process contains 32.0% mol of CO, 64% of H2 and 4% N2. This stream is mixed with a recirculation stream at a ratio of 5 mol recirculation / 1 mol fresh feed to the process. The mixture of these streams forms the feed stream to the reactor, which contains 13.0 mol% of N2. Low conversion is achieved...

A synthesis gas stream consisting of 65.30% H2, 34.30% CO, and 0.400% CH4 (by mole) is fed into the process described below at a rate of 100 mol/hour. The effluent stream from the reactor is fed into a separator where the methanol is completely removed, and the unconverted reactants are recycled to the reactor. To avoid the buildup of methane, a portion of the recycled stream is purged. At present operating conditions, the CO conversion over the entire process is...

Problem 4.80 Methanol Synthesis Methanol is synthesized from carbon monoxide and hydrogen in a catalytic reactor. The fresh feed to the process contains 32.0 mol% CO 64.0 mol% H2 and 4.00 mol% N2: This stream is mixed with a recycle stream in a ratio of 10.00 mol recycle / mol fresh feed to produce th feed to the reactor, which contains 12.0 mol% N2 The reactor effluent goes to a condenser from which two streams emerge: a liquid product stream...

A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent. Components of the gas that are highly soluble, like ammonia, will dissolve into the liquid phase. Water is an appropriate liquid solvent for this process. The chemical plant produces 105.0 m^3/hr of waste gas (rho = 0.0407 mol/L) initially having a mole fraction...
