Abstract |
The paper discusses pilot-plant tests with a 28 cu m/min (1000 cfm) electrostatic precipitator (ESP) to evaluate techniques that have a potential for enhancing the SO2 removal of the E-SOx process for retrofit application. The techniques investigated included mass-transfer additives, improved gas/liquid contact, product recycle, and recycle activation through a combination of hydrating, heating, and mixing. Marginal effects were obtained with the mass-transfer additives tested. Improving the gas-flow pattern and gas/liquid contact had a positive influence on SO2 removal and demonstrated the importance of flow control and spraying system design. Significant SO2 removal enhancement was obtained with recycle operation. When the recycle material was further activated, SO2 removal of 60-65% was achieved at a lime stoichiometry of 1.2. |
