An organic chemical is produced by a batch process. In this process, chemicals X and Y react to form chemical Z. Since the reaction rate is very high, the total time required per batch has been found to be independent of the amounts of the materials, and each batch requires 2 h, including time for charging, heating, and dumping. The following equation shows the relation between the pounds of Z produced (lb,) and the pounds of X (lb,) and Y (lb,) supplied:
Chemical X costs $0.09 per pound. Chemical Y costs $0.04 per pound. Chemical Z sells for $0.80 per pound. If one-half of the selling price for chemical Z is due to costs other than for raw materials, what is the maximum profit obtainable per pound of chemical Z?
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..
A mixture containing 98 mol% methanol and 2 mol% of an inert contaminant is available as a feed to a formaldehyde plant. The fresh feed to a process consists of 1000 kmol/h of this mixture along with 200 kmol/h of oxygen. All of the oxygen is consume..
In the chlorination of ethylene to produce dichloromethane (DCE), the conversion of ethylene is reported as 99.0%. If 94 mol of DCE are produced per 100 moll of ethylene reacted, calculate the selectivity and the overall yield based on ethylene. T..
What is the name for the alkaline hydrolysis of an ester? Discuss the solubility of covalent compounds vs ionic compounds in polar and non polar media respectively.
An elementary second order adiabatic reaction A+ B CD ? + is taking place in a CSTR. The feed to the reactor is equimolar A and B at concentrations of 2.4 mol/liter. The entering temperature is 300 K.
Make a rough estimate of the cost of steam per ton, produced from a packaged boiler. 10,000 kg per hour of steam are required at 15 bar. Natural gas will be used as the fuel, calorific value 39 MJ/m3 (roughly 1 MMBtu/1000 scf). Take the boiler eff..

How will the mole fractions of benzene and toluene in the liquid change with time (increase, decrease, or remain constant)? Explain your answer.
the paint formerly used on some storage tanks contained aluminum powder which reflected heat from the surface of the
Suppose that for mass transfer of species A from a fluid flowing over a flat plate the Schmidt number is much less than one (Sc
The catalyst is in the form of 1/16th inch (1.588 mm) beads with average bulk density of 700 kg/m3 . Design, size, and cost a reactor for making 200,000 metric tons per year of cyclohexane using this process.
Carbon dioxide can be separated from other gases by preferential absorption into an amine solution. The carbon dioxide can be recovered by heating at atmospheric pressure. Suppose pure CO2 vapor is available from such a process at 80°C and 1 bar. Sup..
