3 Monitoring Report No. History of Revisions Version (Date) Reference to Chapter Revision/Rationale ( April 0) Initial Version submitted for verification Introduction The document at hand describes the first monitoring period of the JI Project and documents the achieved GHG emission reductions. It is based on the project s PDD (approved version from 8 April 008), a revised monitoring plan and the JI Manual that serves as amendment to the PDD. Reason for the revision of the monitoring plan is the consideration of leakage emissions related to additional monitoring parameters L and L. The off gas treatment of BASF's adipic acid plant is connected to the nitric acid plant. Usually it is led to the off gas treatment line DK. During certain times it is treated in line DK. Both of these lines are connected to the N O decomposition units. In certain cases of malfunctions of the off gas treatment or maintenance services at the off gas treatment of the adipic acid plant tail gas is led through the off gas treatment of the LP (low pressure) train of the nitric acid plant (see Figure ). This special situation causes leakage emissions so contrary to the original PDD (off gas treatment over DK and DK) the off gas treatment via LP train of the connected nitric acid plant is additionally considered in the revised monitoring plan. The volume flow rates and the N O concentrations of the LP train off gas are measured continuously so the leakage N O emissions are considered in the same way as the project emissions are considered. The Monitoring Report (MR) covers the period from 6 October 009 to 3 January 00. As the Monitoring Report at hand is the first one for the JI Project, the following paragraph holds a brief history of the preparation of the project and construction and commissioning of the redundant catalytic decomposition of residual nitrous oxide (N O) from the BASF adipic acid plant in Ludwigshafen. BASF operates an adipic acid production plant at the integrated production site in Ludwigshafen, Germany. Adipic acid production was established in Ludwigshafen in 939, with the current installation running since 965 and the last capacity extensions to 330,000 tons/yr in 00 and to 370,000 tons/yr adipic acid finalised in 007 (licensed capacity, average production about 300,000 tons/yr). Adipic acid is used primarily as the main constituent for nylon production and is also used as carrier for fragrances, for the treatment of leather, in coatings, synthetic lubricants and fibres, photo chemicals, plastics and more. Two types of decomposition facilities are installed at the plant in Ludwigshafen: Selective Catalytic Reduction of NO x : The share of NO x in the waste gas is decomposed in selective catalytic reduction facilities Selective Catalytic Decomposition of N O: The share of N O in the waste gas is decomposed in a selective catalytic reduction facility On these occasions where the N O decomposition facility was shut down, the N O was released into the atmosphere. The venting of those residual amounts of N O (around 8 to 5 percent of overall N O generation) to the atmosphere is in line with all existing regulations and is approved by the licensing authorities. Although not required to do so, BASF installed a further, redundant, catalytic decomposition facility to decompose the residual N O amounts accruing during shutdown times of the existing N O decomposition facility, and to enhance its decomposition efficiency. With this measure, emissions of the potent greenhouse gas N O from the adipic acid production are reduced to almost zero. As the current waste gas treatment meets all existing regulations and the installation of a further catalytic Page 3 of 8

4 Monitoring Report No. decomposition plant does not generate any economical profit, the revenues from a JI project would alone enable the realisation of this emission reduction project. The JI project was officially approved by the German Designated Focal Point (DEHSt) in March 008 (Date of LoA: March 008). After different tests and approvals, the first day of official operation with the first decomposition and with this the first day of the JI project s crediting period was the 6 October Characteristics of the First Monitoring Period Possible plant specific situations and their handling are described in chapter 4.. of the JI-ADS manual in detail. During the first Monitoring Period absorption train DK was operated with adipic acid off-gas and evaluated during,40 hours, absorption train DK was operated with adipic acid off-gas and evaluated during 79 hours. By-pass of adipic acid off-gas via the LP absorption train occurred, was monitored and evaluated during 3 hours. Adipic acid was produced during the monitoring period with a daily amount of about t adipic acid per day. N O emissions were reduced to 8.94 kg N O/t adipic acid by the second decomposition unit compared to 30.4 kg N O/t adipic acid of the baseline. The calculation of the substitute values in cases of malfunctions due to special situations or analyzer failures is described in chapter 5 of the monitoring plan and chapter 4... of the JI-ADS manual. 4 Monitoring Parameters The following figure gives an overview of the relevant measurements for monitoring. The measuring points are part of the Automated Measuring System (AMS) which has been installed for the reliable monitoring of the JI project. Measured data are described in the tables below.

6 Monitoring Report No. 4.3 Project Emissions of the first Monitoring Period The calculation procedure for the project emissions is described in chapter 4.3 of the revised monitoring plan. The following table shows the calculated results for the total project emissions.

7 Monitoring Report No. 4.6 Baseline emissions of the first Monitoring Period Referring to chapter 4.6 of the revised monitoring plan an adjustment factor is calculated as the ratio of the monitored emissions rate and the historic standard N O emissions rate. In case that the emission rate from the adipic acid production process upstream of the N O abatement facilities is lower than the standard N O emissions rate used for the calculation of historic N O-emissions, the adjustment factor assures that the baseline emissions are not overestimated. Otherwise, if the real rate exceeds the standard value, the factor is capped at a maximum value of to assure conservativeness. For the first monitoring period the real rate exceeds the standard value, so the factor is capped at the value of. The annual quantity of N O baseline emissions is calculated depending on the measured amounts (annual basis) of adipic acid produced multiplied by the historic emission rate EF_N O Baseline for the first monitoring period with tn Q _ N O _ BL = P _ AdOH EF_N O AF = P _ AdOH Baseline t N O = 9,784 t AdOH =,79t N O t AdOH O tadoh AF = Formula Sum of baseline emissions BE (with a GWP of N O of 30) are 865,57 tco e. 4.7 Leakage emissions Data that are collected and recorded under a continuous monitoring are Effluent gas volume flowrates (Q_GE LPout, L) N O concentrations in gaseous effluent (N O_GE LPout, L) The monitoring of these parameters is described in chapter 4 of the JI-ADS manual and chapter 4.7 of the revised monitoring plan, the IDs refer to the tables in chapter 4 of the revised monitoring plan.
