WebThus for multiple bed reactors the average bed temperature for downstream beds is calculated according to eq. 3.3.5.3. It must be noted that both the single bed as well as multiple bed approach is a first approximation. For a more sophisticated WABT estimation please contact SIOP to use the “sliced reactor” approach. WebWABT - Weighted Average Bed Temperature is a way to get one representative temperature from an adiabatic reactor (no heat loss or gain to the surroundings), which in reality have …
