Document Type and Number:
WIPO Patent Application WO/2014/152073
Kind Code:
A3
Abstract:
Systems and methods for step-wise cooling high pressure and high temperature ash discharged from the gasifier used for gasification of carboneous materials, wherein a high pressure cooler cools the ash under the operating pressure of the gasifier, which may be followed by a depressurizer which brings the cooled ash to safe-handling temperature. A low temperature ash cooler may also be optionally used. Also provided is a system where a wet scrubber is used to clean the syngas from the gasifier, the waste water blow down from the scrubber is used to cool the hot ash either in the high temperature ash cooler, or the low temperature ash cooler. Steam generated in the ash coolers is supplied back to the gasifier to reduce steam consumption
