Technology Description

1. High temperature thermal N2O destruction - High temperature (T = 1200-1500 °C) combustion of KA off-gases in a low NOx natural gas or oil fired burner associated with a steam boiler

Key Features

N2O is a bi-product of both adipic acid and nitric acid manufacturing. One tonne of N2O is recognized as having the equivalent climate change effect of 310 tonnes of CO2.  INVISTA has developed world class protocols to measure and verify N2O reduction projects in Canada, USA and the UK.
