Environmental Calculation Formulas
Water Dew Point
The water dew point temperature in a gas stream can be calculated as
Acid Dew Point
The acid dew point temperature for SO2/SO3 in a gas stream can be calculated as:
Cooling Water Injection for Gas Cooling
The required amount of cooling water for gas cooling can be estimated as
(Rule of thumb):
Air Inleakage in Process Filters from Temperature Reading
If the temperature at inlet and outlet of the process is known the air inleakage
can be calculated with a heat balance (dust in process gas is neglected).
For air leakage estimation a cp ratio (process gas/air) of 1.1 can be used and the temperature of the inleakage air can be approximated with the ambient
temperature resulting in:
Air Inleakage in Process Filters from Oxygen Measurement
Inleakage air can be calculated with an oxygen balance over the filter.
