Flowsheet Design and Layout Preparation of Coal Processing Plants

Abstract

Layout of a Coal Preparation plant involves several equipments housed sequentially with the sole objective of producing a coal of certain desired quality. Design of such plant consists of three basic steps viz., development of a flowsheet, equipment selection and layout prepartion. This task is done very judiciously by a team of engineers after several permutations and combinations. For a coal of known washability characteristics, one can design several flowsheets but ultimately the type of flowsheet to be adopted is decided by capital cost and life of the plant operation. The present lecture material has been prepared purely from the academic point of view to bring awareness about the basic information(s) that one need to collect for the design of flowsheet and preparation of a layout. The steps that are to be adopted in designing of such plants, selection of equipments and its layout preparation are described in this lecture in detail. Hence the facts that are narrated in this topic are the information(s) collected from the literature to which the experiences of the author gained over the years in this field has been added.
