Suggest suitable materials of construction for the following applications:
a. A 10,000 m3 storage tank for toluene
b. A 5.0 m3 tank for storing a 30% w/w aqueous solution of sodium chloride
c. A 2 m diameter, 20 m high distillation column, distilling acrylonitrile
d. A 100 m3 storage tank for strong nitric acid
e. A 500 m3 aqueous waste hold-up tank. The wastewater pH can vary from 1 to 12. The wastewater will also contain traces of organic material.
f. A packed absorption column 0.5 m diameter, 3 m high, absorbing gaseous hydrochloric acid into water. The column will operate at essentially atmospheric pressure.
