Power and Chemicals - New Possibilities for the Kraft Recovery Process, 1998 International Chemical Recovery Conference Proceedings
By replacing the conventional kraft recovery furnace with a combined cycle based on the pyrolysis-gasification process it is possible to double the production of electric power. With this process it is also possible to produce two separate streams of chemicals, one sulfur-rich and one sodium-rich stream. Specific requirements from the digester plant concerning the sulfur/sodium ratio will be met at the same time as caustic for the oxygen delignification and bleach plant will be supplied.
