SM-4_Mercury_Stack_Gas_Monitor_ENVEA - 1

Mercury Stack Gas Monitor SM-4 PROCESS & EMISSIONS MONITORING SYSTEMS With more than 20 years of experience as a provider of customized solutions in mercury analysis Mercury Instruments were the first to develop an emission monitoring system that uses a dry thermocatalytic method instead of wet chemistry. The Mercury Stack Gas Monitor SM-4 is ready to meet future measurement standards (Minamata convention & European directives for thermal power plants and incinerators). Designed for accurate and reliable measurement of very low mercury concentrations in flue gases within complex matrices (SO2, NOx, HCl, etc.) SPECIFIC FEATURES: S ampling line length up to 100 m (300 ft) N o liquid waste or condensate generated E xtremely high precision measurement A utomatic back-flush function C ontinuous measurement of total Hg (elementary, ionic & organic) S ample dilution and pre-concentration minimize interference with matrix gases S ample conditioning system (probe, dilution unit and low temperature catalytic converter) is entirely heated to avoid mercury adsorption P robe converter directly at stack: maintenance-free & no transport of ionic Hg O ption to install elemental Hg calibration gas generator, NIST traceable, inside analyzer cabinet V ery low maintenance needed (service interval: ≥ 3 months) – can be automated MAIN APPLICATIONS: 200°C converter box with dilution unit and catalyst cartridge 200°C heated stinger Connectors for dilution air, clean air, purge air, sample, calibration standard Coal fired power plants (before & after mercury absorbers) Cement kilns Sulfuric acid production plants Incineration plants (industrial, domestic, medical waste, sewage sludge...) Thermal treatment of contaminated soils, hazardous waste... M etallurgical facilities with potential Hg emissions... COMPLIANCE WITH IED, WID & LCPD APPLICATIONS Sample conditioning system

PROCESS & EMISSIONS MONITORING SYSTEMS The treated sample is transported through a mildly heated sample line up to 100 metres long to a highly sensitive detector featuring an amalgamation unit (proprietary Mercury Instruments GoldTrap) for preconcentration. The detector uses Cold Vapor Atomic Absorption Spectrometry (CVAAS) at a wavelength of 253,7 nm. Both sample dilution and pre-concentration minimize interferences caused by SO2, NOx, HCl, VOCs etc. TECHNICAL SPECIFICATIONS Measuring range Detection limit Response time Temperature range Sample line length Power supply Electrical power...
