N2O avoidance
RWE Power, acting along with the Austrian company Carbon Projektentwicklung, manages the Carbon Climate Protection joint venture. Here, we develop, finance and operate CDM/JI project activities in which nitrous oxide (N2O, laughing gas) in the waste-gas stream of nitric-acid plants is catalytically degraded.
The AM0029 methodology for avoiding N2O was developed by Carbon Projektentwicklung in 2006 and approved by the UNFCCC.
In project implementation, both methodologies in the N2O area – secondary and tertiary avoidance – approved by the UNFCCC can be put into practice using tried-and-tested technology. Experienced technology partners are available for this.
By the adoption of innovative catalyst technology, very high N2O abatement rates of up to 99% are achieved. These are continuously monitored by online measurements at the inlet and outlet of the catalyst unit, enabling easy and reliable monitoring of the project's success.
Examples of successful project implementation include the world's first CDM project of this type in the nitric-acid plant of Abu Qir Fertilizer Company in Egypt, the biggest CDM project in Africa, as well as the projects at Hu-Chems Fine Chemicals Corp. in South Korea and ENAEX S.A. in Chile.
