The Course

Transport of solids in the form of hydraulic and pneumatic conveying has progressed enormously since its beginning over a century ago. Industries concerned with the processing of particulate solids, have employed hydraulic or pneumatic transport of solids in almost all plants: the examples of catalyst, polymer particles, china, clay, pigments, paints, foodstuffs, etc. In these process industries, the greatest bulk is in the solid state and almost always in particulate form. In the chemical industry alone, the value of product formed as particles is greater than 30% of the whole. The handling of particles is very important and often done wastefully from an engineering point of view. Improvements could lead to considerable savings over wide range of industries.

Because of the complex nature of interaction between solid particles and intervening, the subject of transport solids in the form of hydraulic transport and pneumatic conveying is difficult and multi-faceted. The entire system is difficult to design and it is even more important to be operated and maintained properly. In order to decide whether hydraulic or pneumatic transport is viable solution, it is necessary to know the costs of the entire process including solids preparation, pumping or compressing, pipeline and solids post-processing. The course is very practical and provides information on materials, equipment, design, operation, maintenance and troubleshooting. The practical numerical examples and workshops are designed to facilitate and solidify the understanding of the material.

Highlights of the course include:

·         Principles of selecting the most appropriate means of transport of solids for the given application

·         Guidance for optimum performance and in trouble-free operation

·         Practical real-life examples of how to calculate slurry pipeline or pneumatic piping system

·         Interplay of various influencing design parameters
