US 2006/0213197 A1 · Air pollution control system for ocean-going vessels

Abstract

A platform mounted emissions control unit includes a first system to reduce Particulate Matter (PM), Sulfur Dioxide (SO2), and Volatile Organic Compounds (VOCs), and a second system to reduce Oxides of Nitrogen (NOx). The systems serially process exhaust from a mobile or stationary pollution source. In one embodiment, first system is an Ionizing Wet Scrubber (IWS) and the second system is a Selective Catalytic Reducer (SCR), wherein the IWS processes the exhaust first to improve efficiency and service life of the SCR. A generator produces power required by the IWS and SCR, and heat from exhaust of the generator may be used convert urea to ammonia for use by the SCR, and to heat the exhaust flow into the SCR. The SCR may further include a heat exchanger to capture heat in the flow out of the SCR and use the captured heat to heat the flow into the SCR.

Dependent claims

A palletized emissions control unit comprising:

a platform;
a first system mounted to the platform and adapted to receive a dirty flow and reduce Particulate Matter (PM) and Sulfur Dioxide (SO2) in the dirty flow to produce a first processed flow from the first system;
and
a second system mounted to the platform and adapted to receive the first processed flow and to reduce Oxides of Nitrogen (NOx) in the first processed flow to produce a second processed flow from the second system;
wherein:
the first system and the second system are connected to serially process a gaseous flow to reduce PM, SO2, and NOx in the flow;
and
the first system and the second system operate on power generated on the platform.
