Sulfur dioxide produced by the combustion of sulfur in air is absorbed in water. Pure SO2 is then recovered from the solution by steam stripping. Make a preliminary design for the absorption column. The feed will be 5000 kg/h of gas containing 8% v/v SO2. The gas will be cooled to 20 °C. A 95% recovery of the sulfur dioxide is required.
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
A plant has a batch of 100 kmol of a liquid mixture containing 20 mol% benzene and 80 mol% chlorobenzene. It is desired to rectify this mixture at 1 atm to obtain bottoms containing only 0.1 mol% benzene. The relative volatility may be assumed con..
The liquid stream from the scrubber goes to a dryer where the water is driven off leaving pure maleic anhydride - The moles of benzene that are completely oxidized in the reactor per mole of benzene fed into the reactor?
Consider an inventor who claims to have invented a device which, upon activation, becomes colder when a liquid solution crystallizes spontaneously at constant pressure. Considering the laws of thermodynamics, should a government patent office deny hi..
Circle all answers that are correct; there can be 0 to 5 correct answers. Which of the statements below is true?
The scaling factor k must be such that the total probability is one. Therefore, we have k = 1/36. The table shows one instance where x + y >5, which is x = 3, y = 3. The probability is p = 9/36 = 1/4.
The potential energy between two atoms A and B are constants and r the interatomic separation distance.
Calculate the equilibrium conversion, then redo parts (a) through (c) to achieve a concentration that is 90% of the calculated equilibrium conversion.
Analysis of these publications outline the chiral ligands used and draw a catalytic cycle for one initermolecular and one intramolecular reaction - the asymmetric Heck reaction
Suppose that R2 is decreased to 0.5 min/ft2. Compare the old and new values of the ultimate gain and the critical frequency. Would you expect the control system performance to become better or worse, justify your answer.
A fresh feed stream containing 4.0 mol% inert gas and a stoichiometric ratio of hydrogen and nitrogen is combined with a recycle stream and is fed to a system to produce ammonia according to the reaction: N2 + 3H2 = 2NH3
