Abstract

The present invention relates to a process for the separation of melt and preferably also solid particles from a gas flow, wherein the said flow arises from the gasification of spent liquor from pulp production, preferably black liquor, and comprises both gaseous substances (4) and melt and possibly also solid particles (5), which gas flow is conducted to a separating arrangement (2) where at least a certain portion, preferably the major portion, of the said particles (5) is separated from the gas stream (4), wherein the said flow of gaseous substances (4) containing melt and/or solid particles (5) is forced to move in a curved path and at least the outer periphery of the said curved path is delimited by a mobile liquid layer (12), wherein the said particles (5) are separated from the gas stream (4) by being amalgamated with, and preferably also dissolved and cooled in, the said liquid layer (12).
