Abstract
Combustible carbonaceous and sulfur-containing wastes, especially waste liquors of cellulose plants, are burnt with a combustion-sustaining gas having a greater oxygen concentration than atmospheric oxygen (e.g. pure oxygen) and the gaseous products of the combustion are subjected to scrubbing to remove carbon oxides. The process is carried out under pressure and preferably with two-stage combustion so that carbon monoxide produced in an initial stage can be burnt further in the combustion chamber of a gas turbine to drive the latter and generate at least part of the power necessary to operate the compressor for the oxygen-rich gas.
Claims10
A process for the decomposition of a carbonaceous and sulfur-containing waste comprising the steps of burning said waste with a combustion-sustaining gas stream having an oxygen concentration of at least 50% by volume to produce an exhaust gas containing carbon oxides and sulfur dioxide;
- and scrubbing said sulfur dioxide from said exhaust gas to produce a scrubbed gas substantially free from sulfur oxides and a scrubbing liquid containing sulfur dioxide.
