Hydrocarbon Absorber Design
Because of its similarity to distillation, many parts of this subject have already been covered, such as As for distillation, shortcut hand calculation methods exist, for hydrocarbon absorption. In distillation, relative volatility a values are generated from the K values. For hydrocarbon absorption the K values are used to generate absorption and stripping factors. The 1947 Edmister1 method using effective overall absorption and stripping factors and the well-known Edmister graphs are very...

Time to Evacuate
To estimate the time required for an ejector to evacuate a system from atmospheric pressure down to the design pressure, assume that the average air handling capacity during the evacuation period is twice the design air handling capacity. Assume also that the actual air leakage into the system during the evacuation is negligible. The approximate evacuation time is Tc Time to evacuate a system from atmospheric pressure to the design pressure of an injector, min. V System volume, vapor space, cu....
Silica in Steam
Figure 1 from GPSA shows how the silica content of boiler water affects the silica content of steam. For example at l,600psia, 100 ppm silica in the boiler water causes 0.9 ppm silica in the steam. If this steam, were expanded to lOOpsia, following the steam line down the saturated and superheated curves converge by the time lOOpsia is reached , the solubility of silica decreases to 0.1 ppm. Therefore the difference 0.8 ppm would tend to deposit on turbine blades. The American Boiler...
