ABSTRACT:
Apparatus and method for removing gaseous components and/or solid impurities from a gaseous fluid flow by introducing a first scrubbing liquid into contact with the gaseous fluid flow in a pre-purification section to pre-purify the same. The pre-purified gaseous fluid flow is then conducted to the region of the scrubber impeller in the fine-purification section with a second scrubbing liquid being introduced into contact with the pre-purified gaseous flow as the latter is conducted to the region of the scrubber impeller. The flow of the pre-purified gas is accelerated as it is conducted to the region of the scrubber impeller, such as through a conduit which tapers in cross-section in the direction of gaseous fluid flow therethrough. An extremely fine scrubbing of the gaseous fluid is obtained in a reliable manner without the need for large quantities of scrubbing liquid.
