CONDITIONING SYSTEM AND METHOD FOR USE IN THE MEASUREMENT OF MERCURY IN GASEOUS EMISSIONS

摘要

Embodiments of the invention relate generally to systems used to measuremercury in gaseous emissions. In one aspect, the invention is directed to theuse of an inert covalently bonded material selected from silicon carbide(SiC), silicon oxides (SiOn, n = 1-2), silicon nitride (e.g. Si3N4), siliconboride (e.g. SiB6), boron nitride (e.g. BN) and mixtures thereof as materialfor a thermal pyrolysis unit. In another aspect, the invention is directed toan improved pyrolyzer design, in which a thermal pyrolysis unit comprises atailpiece that allows water to be injected at the heated exit of the thermalpyrolysis unit. In another aspect, the invention is directed to the use of acoalescing filter in a scrubbing unit. In another aspect, the invention isdirected to the use of a hydrophobic filter element in a scrubbing unit. Oneor more of these elements may be used in a conditioning module of a continuousemissions monitoring system, for example.
