Suggest suitable materials of construction for the following applications:1. A 10,000 m3 storage tank for toluene.2. A 5.0 m3 tank for storing a 30% w/w aqueous solution of sodium chloride.3. A 2m diameter, 20 m high distillation column, distilling acrylonitrile.4. A 100 m3 storage tank for strong nitric acid.5. A 500 m3 aqueous waste hold-up tank. The wastewater pH can vary from 1 to12. The wastewater will also contain traces of organic material.6. A packed absorption column 0.5 m diameter, 3 m high, absorbing gaseoushydrochloric acid into water. The column will operate at essentially atmosphericpressure.
