M/BC/CEN/91/14 - Measuring equipment for HCl

This standard specifies a method for sampling and filtration of gases, in view of their HCl concentration determination. Subsequent HCl absorption and analysis are described in prEN 1911-2 and prEN 1911-3 respectively. The method applies to ducted gaseous streams emitted by waste incinerators, and more generally to waste gases in which HCl concentration may vary between 1 mg. m-3 and 5000 mg.m-3 under normal pressure and temperature conditions. The method is validated for gaseous streams of dust concentration below 100 mg.m-3, and is not suitable for measurement of molecular chlorine Cl2 content.

This European standard specifies methods for analysis of chlorides resulting from hydrogen chloride absorption, according to prEN 1911-2, in waste gases having been sampled and filtered according to prEN 1911-1. All compounds which are volatile at the filtration temperature and produce chloride ions upon dissolution during sampling are measured by this method, which gives therefore the volatile inorganic chlorides content of gases expressed as HCl.

This European standard specifies a method for the absorption of hydrogen chloride, in waste gases having been sampled and filtered according to prEN 1911-1. The resulting absorption solutions is subsequently analyzed according to prEN 1991-3. The method described applies to ducted gaseous streams emitted by waste incinerators and more generally to waste gases in which HCl concentration may vary between 1 mg.m-3 and 5000 mg.m-3 under normal pressure and temperature conditions. Note: For the purposes of this standard, normal pressure and temperature conditions are 101,325 kPa and O°C (273,15 K).
