Pulping Principles and Engineering

South China University of Technology via XuetangX

Overview

Paper and paper products are important basic materials in China and also essentials in people's life, so pulp and paper making is an important industry. Papermaking has a long history, but modern pulping and papermaking involves many modern chemical, chemical engineering and intelligent control technologies, and is related to the efficient use of environment and resources. Thus, pulping principles and engineering is embracing the future with new forms. At present, following the progress and development of technology, traditional pulping and papermaking engineering have to face new requirements and challenges. Therefore it is necessary to continue to explore and study, and further spread the knowledge of pulping principles and engineering, so as to meet the needs of the industry and promote the development of the industry. Pulping principles and engineering is a core course for an undergraduate degree in Light Chemical Engineering. It will introduce the theory, technology and process of pulping of plant fiber, bleaching of pulp, recycling of liquid and solid waste.
