M.T. Tham

<<Distillation is based on the fact that the vapour of a boiling mixture
will be richer in the components that have lower boiling points. Therefore, when this vapour is cooled and condensed, the condensate will contain more volatile components. At the same time, the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently. Although many people have a fair idea what "distillation" means, the important aspects that seem to be missed from the manufacturing point of view are that: distillation is the most common separation technique; it consumes enormous amounts of energy, both in terms of cooling and heating requirements; it can contribute to more than 50% of plant operating costs.>>

<<Process heat integration is an important concept for the design
engineer. In a typical chemical plant or refinery, a large number of process streams are being heated and cooled. As a way of minimising utility demand (usually steam and cooling water) these process streams can be run against one another to achieve the same objective heating requirements. That is, hot process streams that need to be cooled can be placed in a heat exchanger with cold process streams that need to be heated, in order to save on utility usage. This course introduces a programmed design method and discusses some considerations for integrating plant heat transfer requirements.>>

<<Solid-Liquid Separation is a major unit operation that exists in
almost every flowscheme related to the chemical process industries, ore beneficiation, pharmaceutics, food or water and waste treatment. The separation techniques are very diverse and the objective of this site is to provide a platform for plant and design engineers, research personnel and students to discuss practices, experiences and new developments in this fascinating unit operation.>>

MB Solutions

<<25 years ago, nearly every drawing produced in the world was done with
pencil or ink on paper. Minor changes meant erasing and redrawing while major changes often meant recreating the drawing from the scratch. If a change to one drawing affected other documents you were dependent upon having someone manually recognize the need to make the changes to the other drawings and to do so. CAD has fundamentally changed the way design is done.>> Received on Thu Nov 09 17:33:00 2000
