PPT111 Introduction to Pulp &
Paper Technology
3 Credits
This course serves as an introduction to the study of pulp and paper
technology. It will focus on providing the student with an overview of the
entire pulp and paper manufacturing process. The course defines and
discusses the properties of wood and wood fibers, wood and chip handling,
the various pulping methods utilized (including cooking equipment,
processing of pulps, and chemical recovery), paper machine stock
preparation, paper manufacture, properties and testing of pulp and paper,
process control, and pulp and paper industry environmental considerations. A
special section on quality assurance is included.
PPT113 Paper Making Processes
3 Credits
This course covers basic papermaking technology. Topics include
preparation of stock for papermaking (including secondary fiber), additives
to papermaking stock, wet-end and dry-end paper machine operations, paper
surface treatments, manufacturing of specific paper and board grades, and
paper testing. Papermaking processes are discussed in the context of basic
chemical and mechanical principles including steam properties,
thermodynamics, hydraulics, and paper machine wet-end chemistry.
Pre/Co-requisite: PPT111.
PPT115 Pulping Technology
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.
PPT116 Maintenance for Pulp & Paper Manufacturing Facilities
3 Credits
This course introduces various concepts and practices used in
maintenance in the pulp and paper industry. Maintenance organization,
work-order systems, planning, scheduling, and work measurement and standards
are reviewed in detail. Special emphasis is given to preventive maintenance,
including the role of various predictive maintenance methods. Maintenance
materials control and the use of computerized maintenance-management
information systems are discussed. The student is introduced to new
maintenance concepts such as Total Productive Maintenance (TPM) and
Reliability Centered Maintenance (RCM). Practical maintenance
trouble-shooting techniques are discussed. Specific maintenance safety
considerations such as lockout/tagout and confined space entry are detailed.
Pre/Co-requisite: PPT111.
PPT117 Safe Work Practices in the Pulp & Paper Industry
3 Credits
This course introduces the student to the elements of occupational
safety with special emphasis on identification of safety hazards and unsafe
work practices as identified by the Occupational Safety and Health
Administration. The importance of personal protective equipment is stressed.
Methods to reduce the risk of personal injury are explained and discussed.
The role of safety training in creating the proper attitude toward safety is
indicated. Special emphasis is placed on hazardous materials used in the
pulp and paper manufacturing processes, boiler and recovery boiler
operations, as well as paper machine and related finishing operations. Safe
work practice for maintenance personnel is outlined.
Pre/Co-requisite: PPT111.
PPT219 Basic Paper Industry Process Chemistry
3 Credits
This course begins with a thorough review of general chemistry
principles. Following this, the chemistry associated with both pulping and
papermaking is examined in depth. Kraft and sulfite pulping processes are
reviewed, and as each unit operation is examined, appropriate analytical
calculations are demon-strated. Polymer and carbohydrate chemistry is
discussed prior to studying wet-end paper machine technology. Attention is
then turned to concepts and applications of colloid chemistry to papermaking
processes. The specific technology related to sheet formation, internal
sizing, wet/dry strength resins, and dyestuffs is explored. Other issues
studied include foam control, pitch control, and first-pass retention
performance on a paper machine.
Prerequisites: PPT111, PPT113, PPT115, CHE112.
PPT223 Process Instrumentation and Control
3 Credits
This course focuses on the four major areas in automatic control
systems: primary measurements, signal transmission, automatic controllers,
and the final control elements. How these areas work together as systems is
shown by describing typical installations as applied in various pulp and
papermaking processes. This course also provides a basic introduction to the
application of computers in control systems utilized in the paper industry.
Prerequisites: PPT111, PPT113, PPT115.
PPT225 Quality Aspects of Pulp and Paper Manufacture 3 Credits
In this course, the importance of quality in the manufacture of pulp and
paper is stressed, and the various ways quality needs are manifested are
explored including quality of raw materials; quality associated with product
requirement, not only to the customer, but within the manufacturing
facility; quality and its relationship to process optimization; and quality
requirements for equipment and people performance. The student will have the
opportunity to perform basic pulp and paper tests and have modern quality
philosophies detailed together with tools for systems analysis and basic
statistical methods.
Prerequisite: PPT111.
