The objective of this work was to determine the feasibility of applying the Surfactant Enhanced Scrubbing technique to the removal of sulfur dioxide using an ejector venturi scrubber.

Surfactants were chosen according to information from manufacturers. Those surfactants which offered good behavior in the presence of acidic solutions ( low pH ), and anti-corrosion characteristics were tested.

In the first phase, experiments were performed to determine the behavior of the foams in the ejector venturi scrubber. A foam destruction system was used when foaming conditions required it. In the second phase dynamic runs were performed to determine the removal efficiencies for each surfactant at various concentrations.

These studies determined that the application of Surfactant Enhanced Scrubbing technique in the ejector venturi scrubber is very practical and promising. Further research should be done to improve this technique.
