The Role of Graphics in Process Control
... graphics. It is important to plan early so that all graphics for a particular project are consistent, and the amount of time spent revising is minimized. Specific colors should be chosen to represent vessels, pipelines, pumps, fans, and any other process ...
Catalyst - Preparation and Characterization
... thermal degradation, (4) vapor compound formation accompanied by transport, (5) vapor-solid and/or solid-solid reactions, and (6) attrition/crushing. Finally the characterization of the catalyst is necessary at every stage of development ...
Cyclone
... air spirals round the cylinder to create centrifugal forces which are created by the spinning stream. According to Perry and Chilton (1973), the centrifugal separating force or acceleration may range from five times gravity in very large diameter, low resistance cyclones to 2500 times ...
Adsorption
... of air, gases, and liquidsSilica gelDrying and purification of gases; refining of petroleum distillatesBase-exchange silicateWater treatmentMagnesiaTreatment of gasoline and solventsAdsorption from the liquid phase is used to remove organic components from drinking water or aqueous wastes, colored ...
Reynolds Experiment
... amount of dye injected through the liquid, which was controlled by a needle valve injector. Since the dye has a higher specific gravity than water, methylene blue flowed along with the mainstream. SUMMARY AND ...
Sedimentation
... of marking the heights of the interface. If adequate accuracy is needed, infrared sensors in tandem with computer software may be used to measure the decreasing interface height as a function of time ...
Fuel fundamentals
... of energy. In the table bellow we can see the different sources of the fuels. Fig 4 fuel sourcesCombustion is a chemical reactionIn a chemical reaction, molecules are broken up and their atoms are rearranged to form different kinds of molecules. Bellow is the example of ...
Haber process
... catalyst. It is a substance that alters the rate of a chemical reaction (speeds it up) without itself being permanently changed (consumed). The catalyst is part of the optimum conditions for producing ammonia from nitrogen and hydrogen. 5. a) The most common types of ...
Pipe corrosion
... development of plastic piping, this is now more possible than ever. Another way to minimize pipeline corrosion is to keep the amount of fittings and especially elbows to a minimum. Inclination of the pipe may also be of ...
Fire Protection
... amount of time).The only potential risk to safety from concrete in fire is spalling, however in most cases concrete does not require any additional fire protection. The factors that lead to spalling of concrete are rapid rates of heating, large compressive stresses and ...
