Hybrid Scrubber
Hybrid scrubber reduces SOx emissions to meet the environmental regulations at coastal region. The main source of SOx emissions is burning of fossil fuel which contains high sulphur component in diesel engine. The high sulphur content fuel is used for marine applications because of its less Hybrid expensive. Switching to low price fuel to high price fuel causes burden to ship owners. This causes the SOx emissions in marine environment, thus disturbs marine eco systems, harms human health and violate the regulations. In order to control the SOx emissions from ship engines, designed and developed a hybrid wet scrubber.
Description
It works based on the absorption with chemical reaction, involved to remove pollutants from exhaust gas by dissolving into the liquid. A central piece of equipment, called packed bed column, in which the polluted gas is fed from the bottom and pass upward through packing material. At the same time, solvent is sprayed from the top to wash the pollutants. The down come liquid is again recirculated back using pump. SOx scrubber includes packed bed column, scrubber tank, re-circulation pipe connected with solvent spray nozzle. Recirculation pump, Instrumentations, Suction blower and Control panel. All the parts involved in the scrubber unit is designed and selected based on the standard design criteria. Packed column helps to achieve heat transfer and mass transfer. The exhaust gas contains SOx mostly has high temperature than atm. The packed column is utilized in cooling of hot gases and dissolving acid gases into the solvent. Water will be used as solvent for the physical absorption. However, Alkali solution will be used for continuous effective scrubbing. Packing material with high surface area is used to increase intimate contact between gas and liquid.
