The progress of additives enhancement with the wet flue gas desulfurization(WFGD) process was studied, and the problems and solutions were pointed out. At the same time, compound additives were presented as promising additives, the results showed that the application of compound additives in FGD device is economically feasible. Of course, how to find the appropriate additives(especially compound additives)...
On the basis of the two-film theory, dynamical mass transfer model was deduced for the wet flue gas desulfurization (FGD) with lime, and the relation between the conversion ratio of calcium hydroxide (Ca(OH)2) and reaction time is set up. It is convenient for improving the residence time in the absorption tower in order to increase desulfurization efficiency and absorbent utilization ratio effectively...
This study focused on the characteristics of the removal of ammonia nitrogen in wastewater with spent grains, a by-product of the brewing process. The influences of density of NaCl solution, pH, contact time and initial ammonia concentration were investigated in batch experiments. The largest removal was obtained at pH 8 in 30 min by 20 g/L spent grains modified by 5% NaCl solution when the initial...
