Elective
2nd Cycle Studies - Mestrado
Recommended Prerequisites
Introduction to Biological Processes; Organic Chemistry; Chemical Thermodynamics; Mass and Energy Balances; Transport Phenomena I, II and III; Introduction to Materials and Characterization; Separation Processes I; Separation Processes II.
Teaching Methods
Teaching is provided in theoretical / theoretical-practical sessions, seminars and practices and demonstrations in laboratory. Theoretical concepts, real situations and some practical examples are presented by the professors and invited experts from industry. Oral presentation and discussion, supported by slides and videos, will be the main vehicles of communication. Students are encouraged to discuss and solve case studies and practical problems following, an independent approach and to working in group. Visits to different paper mills are anticipated, as well as laboratories in industry.
Learning Outcomes
It is intended that students know the world and national importance of the pulp and paper industries, understand the basic concepts of the composition and structure of the paper fibers and their relevance for the paper final properties; know the main types of paper products, the main paper components (fibers, fillers and additives) and their role; know the paper chemistry; know the main unit operations of the paper mill (identifying the processes of mass, heat and momentum transfer); know the fundamentals of furnish preparation, refining, sheet formation, surface treatment and converting, know which are the most important paper properties and the methods used to evaluate them; understand the relevance of the quality control; make some simple calculations related to the different stages of the process and major equipment; identify in the paper mill the most important operations and equipment.
