PROCESS FOR WET CLEANING ROAST GASES

摘要

The invention relates to a process for removing the sulphur oxides from the roast gases resulting from the combustion of sulphur-containing fuels in the industrial boilers or in other fields. The process consists in directing the gases to be cleaned in an ascending direction through a one-step cleaning tower, in counterflow with a sludge containing finely divided particles of calcium carbonate with or without other reactive materials, followed by making the cleaned gases flow on a horizontal path for a step of mist removing and the residual heat recovering by means of a heat exchanger.
