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.

This case is suitable for graduate-level quantitative analysis, business and government, environment and sustainability, and global economics courses. Students must consider the tradeoffs between continuing to run an old coal-burning plant and purchasing emissions allowances (EAs) versus upgrading to emissions-reducing wet or dry scrubbers. Reducing emissions creates the possibility of selling the plant's surplus EAs (which are likely to increase in price). Choosing a wet or dry scrubber requires considering installation cost and construction time, variable cost, and SO2 removal efficiency. Ideally, the investment should pay back over time, but management believes some net investment could also be justified. For that, however, complete analyses from both economic and environmental perspectives are required. A supplemental spreadsheet is available to accompany the case (UVA-QA-0726X).

Main Operating

The objective of this work was to study the sodium alkali(Na2S03) FGD process in a pilot-scale column packed column of diameter 0.4m. Main operating conditions affecting SO2 removal efficiency were investigated experimentally. These conditions include pH value of the absorption solution, liquid-gas ratio, superficial gas velocity, inlet SO2 concentration, temperature of absorption solution and initial Na2SO3 molar concentration. The relation between the ratio of desulfurization and every parameter was investigated. And the suitable operational conditions of SO2 absorption in lab are recommended. The experimental results show that SO2 removal efficiency may be over 80% under the following conditions: pH=6-7,L/G=1-2L/m3, gas superficial velocity is 1-1.5m/s, absorption solution temperature is under 50°C,initial [Na2SO3]≈0.3-0.5mol/L,and SO2 initial concentration is 4300 mg/m3. The experimental data can provide the necessary basic data for the design and operation of the practical desulfurization equipments.
