Abstract:
The industrial processing industry is under continuous sustainability pressure from environmental, legal, and financial quarters to use less water, and industrial processing plant designers and operators are obliged to consider the option of operating at higher concentration [1]. As the concentration of fine particle industrial processing suspensions increases, viscous stresses also increase, and inevitably become non-Newtonian in nature. For some years, our industrial flow process research group has been researching the behaviour of high concentration non-Newtonian suspensions in pipes, valves and fittings, pumps and launders, and these will form the focus of the paper. The aim of this paper is to highlight the important practical aspects of these fundamental issues [2], and their implications for design for industrial process suspension handling. In particular, the objective is to present the principal conceptual issues that underpin sound design for industrial process suspensions. The introductory detail of the design process for handling industrial suspensions will be presented in this paper. The important point to make at the outset is that the foundation of sound design for industrial suspension handling does not revolve around the task of choosing or producing special materials and plant - although these are often required. The foundation lies rather in having a good understanding of the industrial suspension fundamental viscous properties, and sustainable industrial process design and operation [3], which is the basis of this paper and our work at the industrial flow process research group.
