The International Maritime Organization (IMO) is strengthening regulations on reducing sulfur oxide emissions, and the demand for exhaust noise affecting environment of ships also increasing. Various technologies have been developed to satisfy these needs. In this paper, a composite scrubber that can simultaneously reduce was proposed, flow characteristics were analyzed. For silencer, vane type...

Abstract A variety of dust control methods are often applied in coal mines, among which the application wet scrubbers has proven to be an efficient technology for removal airstreams, rather than diluting or confining dust. In this paper, a scrubber design was developed. Based on self-designed experimental test platform, total concentration, respirable air volume, and average pressure drops with...
