Zirconium is one of the few metals that retains its structural integrity upon exposure to radiation. The fuel rods in most nuclear reactors therefore are often made of zirconium. Answer the following questions about the redox properties of zirconium based on the half-reaction: ZrO2*H2O+H2O+ 4e^- yields Zr+4OH^- EMF= 2.36 V
Plain carbon steel would be a suitable material for the tanks, but it is essential that the polymer does not become contaminated with iron in storage. Suggest some alternative materials of construction for the tanks.
List the types of separator that could be considered for. Bearing in mind the nature of the process, what type of separator would you recommend for this duty?separating the solids from the liquid
Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0C (called the molar heat capacity of silver). c. It takes 1.25 kJ of energy to heat a sample of pure silver from 12.0C to 15.2C. Calculate the mass of the sample of silv..
When heavy oils are cracked in a catalytic or thermal cracking process, lighter hydrocarbon compounds are formed. Most cracking processes on heavy oil feeds form products with carbon numbers ranging from two to greater than twenty.
Calculate equilibrium products at 500K for the reaction of 1 mole CO and 1 mole H2O according to the water-gas shift reaction (CO • H2O CO2 • H2) as a function of temperature four ways
The process used in the manufacture of aniline from nitrobenzene is described in Appendix F, Design Problem F.8, which is available in the online material at booksite.Elsevier.com/Towler. The process involves six significant stages:
Miscellaneous friction losses due to the tanker outlet constriction and the pipe fittings in the inlet piping are equivalent to 1000 equivalent pipe diameters. The vapor pressure of chlorine at the maximum temperature reached at the pump is 685 kN..
Problem: A 500mm conductor inside an electric motor has a force of 1.5 newtons exerted on it. If it is at right angles to a magnetic field of flux density 0.6 T, calculate the current flowing in the conductor.
Outline the provisions of Occupational Safety and Health Act 2005 with regard to Substances hazardous to health Describe four types of hazard which arise from the use of chemicals
Devise a control system for this reactor, and draw up a preliminary piping and instrument diagram. The following points need to be considered:
The total volume of hydrogen gas needed to fill the Hindenburg was 2.0 108 L at 1.0 atm and 25C. How much heat was evolved when the Hindenburg exploded, assuming all of the hydrogen reacted?
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..
