Question

What arrangements and precautions will be required to store:
a. 30,000 tons of 98% H2SO4
b. 40,000 tons of CNG
c. 15,000 m3 liquid N2.

Answer 1

a) for sulphuric acid of 93-98% cncentration , 316 STAINLLESS steel and viton gasket can be used. mass stored is high so we need to to use 1.8 -2.2 specific gravity wall thickeness.

b) A compressed natural gas storage tanks can be made of thin-walled aluminium liners with a glass/epoxy reinforcement overwind. the hybrid construction allows the high tensle strength.

c) liquid nitrogen is stored in vacuum-insulated double wall tanks consist of two concentric vessels, one is austenitic steel and outer jacket is made of carbon steel with an anti-corrosion primer and a protective environmentally friendly top coat.

Precaution - observe and maintain the design parameter for all instruments carefully and use within the permissible allowable limits.
