ECS provides a highly efficient catalyst for the abatement of N2O from a process flue gas. ECS can deliver a full tertiary system along with associated ASME high pressure vessel fabrication and compliance analyzers. A typical catalyst installation will reduce N2O in excess of 95%.

ECS provides N2O catalyst for the direct decomposition of N2O in process streams. This direct decomposition avoids the use of fuel or other reducing agents resulting in lower operational cost of the catalyst.

According to the EPA the main greenhouse gas (GHG) emitted during nitric acid, caprolactam, and adipic acid production is N2O. More specifically nitrous oxide is formed through side reactions during the oxidation of ammonia at the primary converter. This N2O has a global warming potential of 310 metric tons of CO2 equivalent emissions per metric ton of N2O. Around the world nitric acid production is the main source of N2O emissions in the chemical industry. The EPA has estimated that this results in approximately 15.6 million metric tons of CO2 equivalent, accounting for about 5 percent of all GHG emissions from stationary industrial sources excluding utilities.

Operating Conditions

  • Typical Application: 790 – 1,110° F (420 – 600° C)
  • Pressure: Atm – 140 psig
  • N2O Destruction: 99%

N2O System

ECS’s N2O decomposition catalyst is an iron zeolite extrudate and the catalyst is contained between two internal baskets. The result is a radial flow design that eliminates gas bypassing the catalyst between the sealing surfaces while providing a minimum amount of pressure drop.
