Abstract:
The present invention relates to a method for purifying a tar containing gas stream. The method comprises the steps of:
a) contacting a tar containing gas stream with a washing liquid in a washing unit to obtain a tar containing washing liquid and a purified gas stream;
b) adding an extractant to the tar containing washing liquid to obtain an extraction liquid comprising a tar containing extractant and a regenerated washing liquid;
c) cooling the extraction liquid;
d) after cooling, separating the tar containing extractant from the regenerated washing liquid, and
e) recirculating the regenerated washing liquid to the washing unit.
