Abstract:
1. An apparatus for treating gas comprising acid gases and particulates, the apparatus comprising: a casing; a gas scrubber section located within the casing, the casing having a gas inlet for supplying gas to the gas scrubber section; an electrostatic precipitator section positioned within the casing to receive gas from the gas scrubber section, the casing having a gas outlet for exhausting gas from the electrostatic precipitator section and a scrubbing liquid inlet for supplying scrubbing liquid to the electrostatic precipitator section, wherein the scrubbing liquid inlet is located toward the upper end of the casing; and a partition disposed between the gas scrubber section and the electrostatic precipitator section and comprising means for conveying scrubbing liquid from the precipitator section to the gas scrubber section, wherein the gas scrubber section comprises a packed tower scrubber section positioned directly beneath the electrostatic precipitator section within the casing and receives scrubbing liquid only from the electrostatic precipitator section via the means for conveying scrubbing liquid from the precipitator section to the gas scrubber section, the casing having a scrubbing liquid outlet for draining scrubbing liquid from the gas scrubber section.
