Division Averaging periods and reference conditions for air emissions
United Kingdom
Emission levels associated with the best available techniques (BAT-AELs) given in these BAT conclusions refer to standard conditions: dry gas at a temperature of 273 K, and a pressure of 1 013 hPa.
Values given in concentrations apply under the following reference conditions:
| For sintered dolime produced by the 'double-pass process', the correction for oxygen does not apply. | ||
| For dead burned magnesia (DBM) produced by the 'double-pass process', the correction for oxygen does not apply. | ||
| Activities | Reference conditions | |
|---|---|---|
| Kiln activities | Cement industry | 10 % oxygen by volume |
| Lime industryf1 | 11 % oxygen by volume | |
| Magnesium oxide industry (dry process route)f2 | 10 % oxygen by volume | |
| Non-kiln activities | All processes | No correction for oxygen |
| Lime hydrating plants | As emitted (no correction for oxygen and for dry gas) | |
For averaging periods the following definitions apply:
| Daily average value | Average value over a period of 24 hours measured by the continuous monitoring of emissions |
|---|---|
| Average over the sampling period | Average value of spot measurements (periodic) of at least 30 minutes each, unless otherwise stated |
