Stat Method

Dissolution rate of limestone for wet flue gas desulfurization in the presence of citric acid was measured by pH-stat method. It was found that limestone dissolution rate in the presence of citric acid was controlled by mass transfer. As can be seen from the experimental results, in the presence of citric acid, limestone dissolution rate increased with increasing stirring speed and reaction temperature. When pH value was greater than or equal to 5.5, due to the formation of calcium citrate, citric acid would inhibit the dissolution process of limestone. And the inhibition effect was more obvious at higher pH value.

Sulfur Dioxide Removal

A new wet FGD process in which sulfur dioxide was absorbed in the bubble reactor using granular limestone simultaneously adding acetic acid had been proposed. The main difference compared to conventional wet FGD process was the ability of the new process to utilize granular limestone directly as a desulphurization reagent simultaneously adding acetic acid. Thus, the pulverizing of limestone, which causes power consumption, can be saved. Only using granular limestone directly as absorbent without acetic acid, SO2 removal efficiency and limestone utilization were too low. Adding some concentration of acetic acid, the performance of the new wet FGD process was confirmed to be equal to or higher than that of a conventional process in various tests. Various parameters of the new FGD process which would affect the sulfur dioxide removal efficiency and limestone utilization were studied.
