A high-performance scrubber especially created for effective dust removal under various circumstances is the radial flow scrubber. The scrubber is provided with an adjustable scrubbing zone that is heavily sprayed with a central nozzle in order to respond to varying flow rates and dust loads.
The Global Radial Flow Scrubber market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Development and calibration of a model for packed bed marine scrubbers aboard ocean-going vessels.Scrubbers have become more important in the maritime industry as a result of recent sulphur emission legislation tightening.
For a packed bed marine scrubber, a model framework based on an Eulerian-Eulerian multiphase model has been created. Both dispersed droplets and a packed bed are taken into consideration by the framework, which applies sub-models for interfacial forces and heat- and mass transfer to the appropriate locations.
The liquid that is used to absorb the SO2 from the exhaust gas is operated in either a closed loop mode or an open loop mode for scrubbers intended for maritime usage. When operating in closed loop mode, fresh water is utilised as the scrubbing liquid, and a neutralizer such calcium carbonate or sodium hydroxide is added as the water becomes acidic from a buildup of sulphur species when it is recirculated through the scrubber.
While in open loop mode, seawater is led back into the ocean after passing through the scrubber only once. The open loop method is frequently employed since it has a low operating cost and occupies little space on board because no supporting equipment for water treatment are needed.
Additionally, boundary conditions and a chemical model are put into place for the nozzles that inject seawater into the scrubber. The model framework is calibrated using data from an ocean-going vessel, where the model’s predictions were within 3% of the actual pressure loss while accounting for temperature differences between gas and liquid. The model predicts a range in sulphur concentration. With the exception of one data set, the concentrations were all within 5 ppm of the measured values.
