Abstract
Low grade heat recovered from various sections of an integrated gasification system is used to drive an absorption chilling cycle. In an exemplary embodiment, the recovered low grade heat is used to heat a two component working solution that is pumped through a closed cycle absorption chilling system. The heated working solution is separated into a rich stream and a lean stream. The rich stream is condensed to produce a liquid rich stream that is throttled to reduce its temperature and then evaporated to produce a cooling load. The cooling load may be used for auxiliary cooling needs in the integrated gasification system. The rich vapor stream produced by the evaporating step is mixed with the lean stream to produce a mixed stream, which is cooled in an absorber to produce the working solution for the cycle to be repeated.
