Phillip R. Westmoreland,Peter A. Kollmanhe filter cake must then be removed from time to time by some form of cleaning process. The cleaning techniques most commonly used are shaking, reverse flow and reverse pulsing. The dust removal efficiency of fabric filters generally lies in the region of 99 to 99.9%. Operating pressure drops are ge

Bioethics Education and Nonideal Theory two main types of filtration behaviour: ‘depth’ filtration and ‘surface’ (or ‘barrier’ or ‘cake’) filtration (Figure 6.1). In depth filtration, collection of particles from the gas occurs throughout the filter medium, which usually consists of fibres or grains (see Section 6.2). In surface filtrati

Gail Steptoe-Warren,Thomas Rhys Evansbility of the medium to withstand operation at elevated temperatures is the principal reason for the choice of this type of filter, but other advantages, such as resistance to attack by acid gases, are also important. This chapter sets out some of the basic considerations involved in the selection a

Technical advances promise to raise temperature limits even further, as new processes that run at well over 1000°C leave the labora

Navigational Bridge Layout and Arrangementsith the dimensions of the particles to be filtered. Granular bed filtration is therefore not ‘absolute’ in the sense that surface filtration can be, although ‘absolute’ filtration is approached for a fixed bed filter if a ‘cake’ forms on the up-stream face. Furthermore, collection efficiency will of

The main condensable inorganics are salts, primarily the chlorides of sodium and potassium. Understanding their behaviour depends in part on understanding the thermochemistry of their reactions.
