On the basis of high water consumption property of the wet gas desulfurization(FGD) technology
several operation conditions such as the limestone-gypsum method
magnesium method and natrium-alkali method were simulated to investigate the effects of parameters like the vapor concentration in flue gas
the circulating slurry temperature
the inlet flue gas temperature and other parameters corresponding to different water contents in the original coal on water consumption of FGD.The results show that
all the vapor concentration of the flue gas
the temperature of the inlet flue gas and the circulating slurry temperature have a significant influence on the water consumption due to the moisture condensation.There exists a group of critical operating parameters allowing for a zero water consumption(ZWC)system to be built for all the desulfurization methods investigated
even when the most commonly used limestone-gypsum method is employed.
