Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective Catalytic Reduction unit (SCR), which deploys ammonia gas NH3 to limit emissions of NO and NO2. A modern nitric acid plant needs to monitor the emissions of these gases.

ABUTEC specializes in providing advanced technology for the CDM initiative and for carbon credit projects in the landfill and waste water industries. The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change, which sets internationally binding emission reduction targets. There are three mechanisms within the protocol, one being the Clean Development Mechanism (CDM). A CDM project must provide emission reductions that are additional to what would otherwise have occurred.
