Abstract

The invention relates to a method of separating sulphur from a cellulose cooking process of a sulphate cellulose plant and of recycling it for being reused. In the method, the sulphur is separated and recovered as odour gases produced at various stages of the process, which gases are passed to combustion of odour gases and oxidated after that by means of a catalyst into sulphur trioxide, which as an aqueous solution produces sulphuric acid. The sulphuric acid again is used for replacing the outside sulphuric acid needed by the plant. (Figure 1)
