PROCESS FOR PRODUCING SULPHUR DIOXIDE, A THERMOCHEMICAL SYSTEM COMPRISING THE PROCESS AND ITS RELATED APPARATUSES, USE OF CARBON-BASED COMPOUNDS TO FEED A PROCESS FOR PRODUCING SULPHUR DIOXIDE AND ITS RELATED SYSTEM

摘要

The invention relates to a thermochemical process for producing sulphur dioxide, a thermochemical system comprising the thermochemical process and apparatuses for the implementation of the process and of the thermochemical system, as well as the use of carbon-based compounds in order to feed a thermochemical process for producing sulphur dioxide and its related system. The process comprises the steps for the collection of concentrated sulphuric acid (S) inside a thermochemical reactor (11) of a thermochemical apparatus for producing sulphur dioxide (10), for the heating of the concentrated sulphuric acid (S) until it boils. The peculiarity of the process is that of adding carbon-based compounds in the thermochemical reactor (11).
