Abstract The invention relates to a method of separating sulphur from a cellulose cooking process of a sul- phate 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 pro- cess, 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)
