Adsorption Method For Sampling Of Dioxins And Furans
Adsorption Method for Sampling of Dioxins and Furans (AMESA) is an automatic system for ''continuous'' monitoring of emissions of dioxins and furans from industrial processes which require official approval in compliance with environmental regulations. Applications include refuse incinerators and hazardous material incinerators. Method A sample is continuously extracted from the gas stream being monitored using a titanium probe, which is water-cooled to below 70 °C (why?). The sample flow rate is automatically adjusted to ensure isokinetic sampling (the velocity of gas entering the sampling system is equal to the velocity of the gas in the system under test). The sample gas is drawn through a quartz Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tet ... wool pre-filter and then ...
