A system for treating exhaust gas of a vessel having at least one engine equipped with a turbocharger includes a storage tank configured to store a powder for treating the exhaust gas, and a dosing assembly fluidly coupled to the storage tank. The dosing assembly is configured to inject the powder into the exhaust gas at or adjacent the turbocharger, and includes a nozzle for injecting the powder into the exhaust gas. The nozzle includes a conduit configured to transport the powder, and a conical member mounted to a distal end of the conduit and defining a central hole in fluid communication with the conduit for guiding a first portion of the powder through the central hole. The distal end of the conduit and the conical member together define an annular gap configured to guide a second portion of the powder through the annular gap.
