2.B.3 - Adipic Acid Production

Short description

In source category NFR 2.B.3 - adipic acid production NOx and CO emissions from the production of adipic acid are reported. As there are only three producers of adipic acid, data provided by them has to be treated as confidential. Due to that, only emissions could be reported.

As this source category is a key category for N2O, plant specific activity data is applied here according to the IPCC guidelines. This data is made available basically via a co-operation agreement with the adipic acid producers. A single data Collection of plant specific NOx and CO emissions and related emission factors of one year (2016) was sufficient as the emissions are below the threshold of significance. These emission factors are applied to the whole time series for every plant.
