Inlet And Outlet Humidity
In Dryers In dryers, inlet humidity is a controlled parameter which affects the process, whereas outlet humidity is a monitoring parameter which is affected by the process. Inlet humidity Variations…
Applying Humidity In Calculations
The needs of the practitioner involved in industrial drying are completely different to those of the standards expert. He is not generally interested in predicting or measuring values of humidity…
Humidity effects in dryers
Humidity affects the dryness of the solids it is in contact with. A dynamic equilibrium is set up between the moisture in the solids and the vapour in the air.…
Humidity and its definition
Humidity is a key factor in drying processes. It expresses the amount of vapour in the carrier gas stream (usually air). However, there is often confusion between relative and absolute…
Absolute Humidity
Absolute humidity is the mass of water vapor divided by the mass of dry air in a certain volume of air at a specific temperature. The warmer the air is, the…
Unsteady state energy and mass balances
What IS accumulation? Recall that so far in this text it has been assumed that all systems are at steady state, which means that there is no buildup of mass, energy,…
Bypass Stream
Bypass stream is a stream that skips one or more stages of the process and goes directly to another downstream stage. Purge Stream Purge stream is a stream bled off…
Recycle and Bypass Processes
One of the more common processing configurations is the material recycle structure. These are particularly useful for reactors, where they allow better control of reactor selectivity when multiple reactions occur.…
Reactive Processes
Performing material balances on reactive systems is slightly more complex than for non-reactive systemsN2 + 3H2 -> 2NH3 While we can still do a balance on total mass, this is often not…
