The competing chemical pulping process, the sulfate or kraft process was developed by Carl F. Dahl in 1879 and the first kraft mill started (in Sweden) in 1890. Types of Pulping Processes. Pulp can be divided into two principal types: chemical or mechanical pulp. In fact there are more than two types of pulp . Pulp from  nin) by bleaching; and 4) paper formation and manufacture. A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical,.The 4 processes principally used in chemical pulping are kraft, sulfite, neutral sulfite semichemical (NSSC), and soda. The first 3 display the greatest potential for . The semichemical pulping process involves cooking wood chips in a neutral solution of sodium sulfite and sodium carbonate or sodium hydroxide. Only some of . There are two primary means of chemical pulping.
