PPT 115 - Pulping Technology

Institution:

Kennebec Valley Community College

Subject:

Description:

3 Credits This course begins with an overview of the basic pulping technologies, including mechanical, sulfite, kraft, and semichemical pulping. Because of the increased use of recycled fiber as a fiber source, secondary fiber technology is also reviewed. Kraft pulping is the predominant industry pulping process, so major emphasis is given to this technology. The supporting chemical and mechanical principles for the pulping processes considered are detailed. These include the chemistry of kraft and sulfite liquors, the chemistry of black liquor recovery, recovery boiler operation, steam properties in black liquor recovery systems, recausticizing, calcination, bleaching sequences, bleaching chemicals, and overall pulp mill recovery systems as associated with environmental concerns. The properties and testing of pulps will be discussed. Prerequisites: PPT111, CHE112, CHE114.
