Continuous Mercury and Chloride Monitors for Coal Gasifiers

PDF Version Also Available for Download.

Description

Ames Laboratory will develop an integrated sampling and analysis system suitable for on-line monitoring of Hg and HCl in advanced coal-based gasifiers. The objectives of this project are to 1) summarize current technology for monitoring Hg and HCl in gaseous effluents, 2) identify analytical techniques for such determinations in high-temperature, high-pressure gases from coal-based systems for producing electrical power, 3) evaluate promising analytical approaches, and 4) produce reliable on-line monitors which are adaptable to plant-scale diagnostics and process control. Project Description Commercially available instruments which were potentially suitable for monitoring Hg and HCl in coal gasifiers were screened and the ... continued below

Description

Ames Laboratory will develop an integrated sampling and analysis system suitable for on-line monitoring of Hg and HCl in advanced coal-based gasifiers. The objectives of this project are to 1) summarize current technology for monitoring Hg and HCl in gaseous effluents, 2) identify analytical techniques for such determinations in high-temperature, high-pressure gases from coal-based systems for producing electrical power, 3) evaluate promising analytical approaches, and 4) produce reliable on-line monitors which are adaptable to plant-scale diagnostics and process control. Project Description Commercially available instruments which were potentially suitable for monitoring Hg and HCl in coal gasifiers were screened and the most promising techniques were selected for laboratory evaluation. For Hg, the techniques selected for further consideration were atomic absorption (AA) and atomic fluorescence (AF). For HCl, gas-filter-correlation infrared spectroscopy (GFCIR), a dry calorimetric procedure, and ion mobility spectroscopy (IMS) were selected for testing in the laboratory. The analytical systems selected for use in on-line Hg and HCl analyzers will be adapted for application to monitoring hot pressurized gases from coal gasifiers. Additional work will involve developing suitable gas conditioning and sample introduction systems. That work may be as important as the development of the analytical detectors themselves. After the laboratory studies have been completed, prototype instruments will be tested and evaluated in the field.
