Process and installation for purification of exhaust gases from internal combustion engines |
摘要 |
The process enables the removal of gaseous contaminants from the exhaust gases of thermal engines, particularly diesel locomotives operating in confined spaces. The process comprises the following stages: re-heating of the exhaust gases to a temperature of 300 - 450 degrees C., preferably 350 - 360 degrees C.; treatment of the oxides of carbon and hydrocarbons by catalytic oxidation; addition of a reactant such as urea or ammonia; treatment of oxides of nitrogen by catalytic reduction; cooling of the gaseous flow; treatment of the sulfur oxides by mixing with water in a venturi-effect washer; and bubbling of the residual gases through water. The addition of a reactant is regulated as a function of the nitrogen oxide content in the exhaust gases. An Independent claim is also included for the installation for the process. |
