Abstract
The present application provides a slurry concentration system for concentrating a flow of slurry. The slurry concentration system may include a boiler for producing a flow of steam, a first evaporator for concentrating the flow of slurry with the flow of steam and creating a first flow of water vapor, and a second evaporator positioned downstream of the first evaporator for further concentrating the flow of slurry with the first flow of water vapor and creating a second flow of water vapor.
