Title: METHOD AND SYSTEMS FOR ENERGY RECOVERY FOR MARINE AIR QUALITY CONTROL SYSTEMS
Abstract:
An air quality control system (AQCS) (200) is configured to clean a process gas (106). The AQCS includes a gas cleaning device (202) that receives a process gas (106) containing pollutants and a clean fluid flow (206). The process gas (106) is contacted with the clean fluid flow (206) to remove the pollutants from the process gas (106). Contact of the process gas (106) with the clean fluid flow (206) generates a clean exhaust gas flow (108) and an effluent fluid flow (208). A fluid conduit (228) receives the effluent fluid flow (208) discharged from the gas cleaning device (202), and defines a fluid column (209) height (H) of effluent fluid flow (208). The effluent fluid flow (208) therefore has an amount of kinetic energy based on a height of the fluid column (209). An energy recovery device (210) receives the effluent fluid flow (208) from the fluid conduit (228). The energy recovery device (210) converts a portion of the amount of kinetic energy of the effluent fluid flow (208) to mechanical work.
