Chlorine is to be removed from a vent stream by scrubbing with a 5% w/w aqueous solution of sodium hydroxide. The vent stream is essentially nitrogen, with a maximum concentration of 5.5% w/w chlorine. The concentration of chlorine leaving the scrubber must be less than 50 ppm by weight. The maximum flow rate of the vent stream to the scrubber will be 4500 kg/h. Design a suitable packed column for this duty. The column will operate at 1.1 bar and ambient temperature. If necessary, the aqueous stream may be recirculated to maintain a suitable wetting rate.
Figure shows the tensile engineering stress-strain behavior for a steel alloy. (a) What is the modulus of elasticity?
1. A newly constructed power plant proposes to burn coal with a sulfur content of (a) 1.8 and (b) 2.4 percent by weight. If the plant is to meet the new source review performance standard (see attached CFR new source regulation), what percent of SO 2..

The unit cell for Cr2O3 has hexagonal symmetry with lattice parameters a = 0.4961 nm and c = 1.360 nm. If the density of this material is 5.22 g/cm3, calculate its atomic packing factor.
Natural gas is widely used as fuel in the process industries, so the price of natural gas is often an important variable in economic analysis. Develop a 15-year forecast of U.S. natural gas prices. Historic natural gas prices are available at www...
What were the materials used in the implant? What were the advantages of the materials used and what was the surface texture of these implants? How did this contribute to the biocompatibility of the implant?
A paint mixture containing 25% of pigment and the balance water sells for $18.00/kg, and a mixture containing 12.0% pigment sells for $10.00 kg. If a paint retailer produces a blend in containing 17.0% pigment, for how much ($/kg) should it be sold t..
Express the maximum radius (Rmax) and maximum thickness (Tmax) in terms of bulk oxygen concentration, Cb (mol/mL), diffusivity of oxygen through the device D (cm2/s) and maximum oxygen consumption rate, Vmax (mol/mL/s).
The data in Table 1 were obtained from a kinetic study of an enzymatic reaction. The substrate S (with a concentration s) was converted, using an enzyme, to a product in 4 different experimental runs. The initial conditions of each experiment (initia..
