SULPHURIC ACID MANUFACTURE

ABSTRACT

Sulphuric acid has always been considered as the foundation for inorganic chemicals. It is the wide spread use of sulphuric acid through out industry rather than tonnage that has caused consumption of sulphuric acid to be considered as a dependable barometer of general business conditions which includes manufacturing, utility suppliers and environmental technologies.

Sulphuric acid is manufactured by the combustion of sulphuric acid to produce sulphur dioxide gases, that is being converted to sulphur trioxide and absorbing the gas in water or sulphuric acid. This is the basic principle for all the processes. However we selected the Double Contact Double Absorption process for the manufacture of sulphuric acid.

This project deals with the manufacturing of sulphuric acid at a capacity of 100 tonnes per day. This project involves studying and gathering all the preliminary information required for sulphuric acid manufacture, generating material and energy balances for the plant, designing the equipments involved in the process of manufacturing, estimation of the economics of the plant, layout of the plant and analyzing the safety and environmental aspects.
