pulp capacity and about 55% of the total wood pulp capacity in this area are in kraft mills. About half of the kraft pulps are made into bleached or semibleaehed products. The major reasons for the success Of the kraft pulping process can be summarized as follows: t. An efficient and recovery process has been developed for the pulping chemicals. Size: 2MB. PSE Lecture 6 3 Kraft Pulping: Definition of Terms • White liquor.» Fresh pulping liquor for the kraft process containing NaOH, Na 2 S, and a variety of impurities. • Black liquor.» The waste liquor from the kraft pulping process. Contains most of the original inorganic components (most in different forms) and a high concentration of dissolved organics. 1 CHEMICAL REACTIONS IN KRAFT PULPING IN COOKING The main objective is to facilitate the disintegration of wood into fibrous product. This is achieved by breaking the bonds in the lignin macromolecule. The main chemical reactions in the cooking process can be described as: NaOH + NaS 2 + Wood à Na-org. + S-org. + NaHSFile Size: KB. Sulfate or Kraft pulp is one of the chemical pulping processes. It is manufactured by alkaline method. Kraft pulping process is the dominating pulp manufacturing process in the world. Today this process is most widely used with a production of % of the total Pulp.
Kraft process 1. KRAFT PROCESS 2. • The kraft process also known as kraft pulping or sulfate process • Is an industrial process for conversion of wood into wood pulp consisting of almost pure cellulose fibers • Treatment of wood chips with a mixture of sodium hydroxide and sodium sulfide, known as liquor, • That breaks the bonds that link lignin to the cellulose.
