And Performance

The oily sludge-based adsorbents for flue gas desulfurization were prepared by pyrolysis. Based on benzene adsorptivity, the conditions of pyrolysis process were optimized. The optimum prepared conditions of adsorbent material were in nitrogen atmosphere and 550°C, 4h, 10°C/min for the pyrolysis temperature, pyrolysis time and heating rate, respectively. In this case, the maximum benzene adsorbability was 60.12mg/g. Moreover, the main influencing factor was pyrolysis temperature, secondly was pyrolysis time and finally was heating rate. The sludge-based adsorbents were appropriate for flue gas desulfurization. The sulfur capacity of adsorbents via a flue gas desulfurization test after subsequent processing was about 3% and breakthrough time could keep to 109 min.

ALSTOM’s Flash Dryer Absorber (FDA) system is a dry FGD technology, which aims for simplicity and compactness. This first installation was in Poland at the 2×120 Mwe Lasiska site, and was commissioned in 1996. Since then there have been a number of important developments of technology, notably combination with an ESP, use of integrated lime hydration and use of ash from CFB as the reagent; supported by an ongoing test program. The technology also looks promising for the retrofit area. The combined full-scale plant for the removal of flyash and SO2 can often be fitted into the space occupied by the existing electrostatic precipitators. There are seventeen commercial installations of FDA in various stages of operation, construction, and design.

The full-scale of PC/Cyclone Boilers with common wet flue gas desulfurization (WFGD) with limestone forced oxidation (LSFO) was studied. Ontario Hydro Method (OHM) recommended by the United States Environmental Protection Agency (USEPA) was used to determine mercury emission and speciation at these two full-scale WFGD systems, and OHM quality assurance/quality control (QA/QC) was followed during the field testing. WFGD re-emission problems were repeatedly observed at this unit. Selective catalytic reduction (SCR) had significant effects on mercury removal and Hg0 re-emission rates across WFGD. Effects of injection of continuous chemicals additive containing HS-, S2- or I- on mercury re-emission control were also conducted at this unit.
