What materials of construction should be specified for the thiophane process described in Prob. 20 of Chap. 2? Note the extremes of temperatures and corrosion which are encountered in this process because of the regeneration step and the presence of H2S and caustic.
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:
A factory is producing tablets. It is required to design a system such that: The bottles moves till it reach the position shown (A) and 50 tablets are dropped in
Adsorption and Membrane Processes
It is proposed to use an existing distillation column, which is fitted with a dephlegmator (reflux condenser) that has 200 vertical, 50 mm i.d. tubes, for separating benzene from a mixture of chlorobenzenes.
Research the impact mining has had on the early history of Australia. In approximately 1,500 words choose an Australian town or city where mining started in the 18th or 19th or even early 20th Century and describe its early history.
The enthalpy change of reaction for the balanced equation (with lowest whole-number coefficients) is H 67.7 kJ. If 2.50 102 mL of N2(g) at 100.C and 3.50 atm and 4.50 102 mL of O2(g) at 100.C and 3.50 atm are mixed, what amount of heat is..
Hydrogen gas at a pressure of 1.25 bar is contained in a thick-walled neoprene rubber sphere which has inner and outer radii of 70 mm and 80 mm, respectively.
For a gas flow rate of 100,000 m3 /h, at the reactor conditions, determine how many cyclones operating in parallel are needed and design a suitable cyclone. Estimate the size distribution of the particles entering the filters.
As a system increases in volume, it absorbs 55.0 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.502 atm. The final volume of the system is 57.7 L. What was the initial volume of the system if t..
Five different batches of a commercial plastic are sampled to determine the variation of inert additives between batches. Since each batch consists of several thousand pounds of material, several samples are taken from each batch to determine the ..
