Aiming at investigating the ammonia-based wet flue gas desulfurization(WFGD) process
the influence of process parameters on desulfurization efficiency was experimentally studied on a small scale countercurrent spray tower FGD system
under cold state condition.The results indicated that
the desulfurization efficiency was mainly affected by pH value
which increased from 69.6%to 94.1% when the pH value rose from 4.5to 5.0.The optimal pH value varies from 5.5to 6.0.Properly increasing the residence time of flue gas and enhancing the liquidgas ratio was helpful to the desulfurization efficiency.However
the desulfurization efficiency dropped when the inlet SO2 concentration was increased.
