    Sainmhíniú emissions reduction technique used in combustion engines, where a portion of an engine's exhaust gas is recirculated back to the engine cylinders Tagairt COM-EN, based on:Wikipedia > Exhaust gas recirculation. http://en.wikipedia.org/wiki/Exhaust_gas_recirculation [24.9.2013]
    Nóta In a gasoline engine, this inert exhaust displaces the amount of combustible matter in the cylinder. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture. Because NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature, the lower combustion chamber temperatures caused by EGR reduces the amount of NOx the combustion generates (though at some loss of engine efficiency). Most modern engines now require exhaust gas recirculation to meet emissions standards.

    Sainmhíniú NOx pollution reduction process which implies the reinjection of flue-gas from the furnace into the flame to reduce the oxygen content and therefore the temperature of the flame Tagairt COM-Terminology Coordination, based on:European Commission. JRC. Best Available Techniques (BAT) Reference Document for the Non-Ferrous Metals Industries, http://eippcb.jrc.ec.europa.eu/reference/BREF/NFM_Final_Draft_10_2014.pdf [13.4.2016]
    Nóta The use of special burners is based on internal recirculation of combustion gases which cool the root of the flames and reduce the oxygen content in the hottest part of the flames.

    Sainmhíniú recycling loop of the waste gas from the continuous regeneration unit of the catalyst Tagairt European Commission. Joint Research Centre. Institute for Prospective Technological Studies (JRC-IPTS). European Integrated Pollution Prevention and Control (lPPC) Bureau. Correspondence dated 9.4.2015
    Nóta The process could be simplified in the following steps (in reality there are more than one reactor):Step 1: fresh catalyst is introduced at the top of the reactor (the catalyst allows to upgrade the octane of heavy naphtha which is in the reactor)Step 2: the catalyst flows down by gravity to the bottom of the reactor, and is progressively "spent" during the reactionStep 3: the spent catalyst is removed from the bottom of the reactor and introduced in an external regenerator (Continuous Catalyst Regeneration reforming unit).Step 4: The catalyst is "regenerated" (the carbon is burned from the catalyst)Step 5: The regenerated catalyst is introduced at the top of the reactor, and the cycle starts again
