Kraft Process
Posted on Mei 17, 2008 - by admin, in category News
The kraft process was developed by Carl Dahl in 1879, and a pulp mill using this technology started in Sweden in 1890. The invention of the recovery boiler by G.H. Tomlinson in the early 1930s, was a milestone in the advancement of the kraft process. It enabled the recovery and reuse of the inorganic pulping chemicals such that a kraft mill is almost closed-cycle with respect to inorganic chemicals, apart from those used in the bleaching process. For this reason, in the 1940s, the kraft process surpassed the sulfite process as the dominant method for producing wood pulp. (Source : Wikipedia)
