Gas cyclones and swirl tubes : principles design and operation Believed to be a publishing first when originally brought out this book covers all aspects of centrifugal gas cleaning devices. These are cyclones used as gas solid separators for dedusting and as gas liquid separators for demisting. The optimization of cyclone performance for any given task is a sought after goal but it is one that is seldom achieved in practice. This second edition will help mechanical and chemical engineers to achieve this optimization.
