Abstract

The invention relates to an exhaust aftertreatment arrangement (20, 220) for converting NOx emissions. The exhaust aftertreatment arrangement comprises:- a fluid channel (21, 221) for providing a fluid pathway (26, 226) for the exhaust gases,- a selective catalyst reduction, SCR, catalyst (32), arranged in or downstream the fluid channel,- an injector (34) configured to inject a liquid reductant for providing ammonia to the SCR catalyst, the injector being arranged upstream of the SCR catalyst,- a heating arrangement (38, 138, 238, 338) for heating the injected reductant, the heating arrangement being arranged upstream of the SCR catalyst and comprising an electrical heating element (40, 140) and at least one evaporation member (42, 43, 142, 342) configured to be heated by the heating element. The heating arrangement is removably arranged relative the fluid channel such that, in an assembled state, the evaporation member is arranged in the fluid channel such that at least a portion of the injected liquid reductant comes into contact with the evaporation member when injected.
