1. A system for treating exhaust gas of a vessel having at least one engine equipped with a turbocharger, the system comprising:
a storage tank configured to store a powder for treating the exhaust gas;
a dosing assembly fluidly coupled to the storage tank and configured to inject the powder into the exhaust gas at or adjacent the turbocharger;
a gas analyzer including one or more probes configured to communicate data associated with a sulfur measurement in the exhaust gas; and
a computing device configured to receive the data from the gas analyzer and determine an adjustment to a metering amount of the dry powder injected into the exhaust gas;
wherein the computing device determines the adjustment based on both the data from the gas analyzer and real-time data associated with an amount of fuel injected into the engine.
 
9. A nozzle for injecting a powder into exhaust gas of an engine of a vessel, comprising:
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, wherein 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.
