SETT OCH ANORDNING FOR KEMIKALIEATERVINNING AV MASSAAVLUTAR I KONVENTIONELL SODAPANNA |
摘要 |
The present invention relates to a method and means of increasing capacity and improving the chemical recovery process when using a conventional soda recovery boiler for recovering chemicals out of spent sulphate liquors. The spent sulphate liquor is supplied in full or in part to a liquor gasifier (8) while external energy independent of combustion is simultaneously supplied (at 16, 17). The temperature and oxygen potential are carefully controlled independently of each other by means of controlled supply of the energy. The product thus obtained is thereafter introduced in full or in part into a soda recovery boiler (1). |
