Generation and utilization of ammoniated water in gasification

Abstract

Gasification processes utilizing carbonaceous feeds and preferably biomass are disclosed, which can implement one or more strategies for generating an ammoniated water product having, in addition to alkalinity, suitable purity for utilization in a number of applications, including those within the overall process. Exemplary applications involve neutralization of sump and interfacing slag water systems. Recovery by condensation of this ammoniated water product from an overhead vapor product of a first scrubber contacting stage may be performed in conjunction with a scrubbing operation that utilizes a scrubber vessel containing this scrubber contacting stage and optionally one, two, or more additional scrubber contacting stages, for example separated vertically by individual aqueous scrubber feeds that are input at varying axial heights.
