BS EN 1911 describes the Standard Reference Method (SRM) with three alternative analytical techniques for determining gaseous chlorides content emitting to atmosphere from ducts and stacks.
The method described in BS EN 1911 determines the concentration of chlorinated compounds in a flue gas that – after passage of the sampling system including a particle filter – give Cl- ions in the absorption solution. This Standard Reference Method has been evaluated during field tests on waste incineration.
BS EN 1911 applies to waste gases in which chlorides concentration expressed as HCl may vary between 1 mg⋅m-3 and 5 000 mg⋅m-3 under normal pressure and temperature conditions (see Note 1), and according to emission limit values laid down, for example, in the Council Directive 2000/76/EC on waste incineration plants.
NOTE 1 The limit values of this European Standard are expressed in mg HCl/m3, on dry basis, at the reference conditions of 273 K and 101,3 kPa and at the reference O2 concentration.
NOTE 2 The required uncertainty results from the capacity of the method tested in the field (Annex D) and in the laboratory (see performance characteristics in Tables 1 and 2 and Annex C).
BS EN 1911 on GHG is relevant to:
Stationary sources of air pollution, such as factories, refineries, boilers, and power plants, emit a variety of pollutants.
BS EN 1911 lays out general aspects and requirements for determining mass concentration of gaseous chlorides, benefitting the end-user through accurate estimation and measurements.
BS EN 1911 defines the requirements, definitions, and rules applicable to estimating HCL emission from different sources and provides a step-by-step method of determining mass concentration of gaseous chlorides.
Overall, BS EN 1911 specifies, establishes, and provides the users with reliable, accurate and quality emissions information for reporting and verification purposes.
