Apr 01, 2016 A kraft pulp mill can be divided into four main parts: (1) raw material handling; (2) pulping line with an almost closed chemical and energy recovery system; (3) bleaching with an open water system and (4) the external wastewater treatment system. Figure 5 shows the emissions sources to water from a kraft pulp mill.

Oct 02, 2011A modern Kraft pulp mill produces more heat and power than necessary for the process. In existing mills, improved Process Integration typically enables reduction of heat consumption by 15–30%. Over time, specific energy consumption can be decreased in existing mills thanks to Process Integration studies.

Comparison of Chemical Pulping and Mechanical Pulping
There are some differences between the two types of pulp. Mechanical Pulp In the production of mechanical pulp, goldare ground against a water-lubricated rotating stone. During this process, the heat generated by grinding softens the lignin-containing fibers, and the mechanized forces separate the fibers to form the ground we want.
