Monthly Technical Report

1 Monthly Technical Report (Due to AQRP Project Manager on the 8 th day of the month following the last day of the reporting period.) PROJECT TITLE PROJECT PARTICIPANTS (Enter all institutions with Task Orders for this Project) REPORTING Quantification of Industrial Emissions of VOCs, NO2 and SO2 by SOF and mobile DOAS Chalmers University of Technology University of Houston (UH) PROJECT NUMBER DATE SUBMITTED /08/11 From: May 1, 2011 REPORT 3 PERIOD To: May 31, 2011 NUMBER Invoice Number that accompanies this Report: Chalmers: 3 UH: Amount of funds spent during this reporting period: Chalmers: $24, UH: $56, Detailed Accomplishments by Task (Include all Task actions conducted during the reporting month.) Task 3. Intensive campaign During May 1-20, 2011, the intensive campaign continued in north eastern Texas. During May 1 to 6 emission measurements of alkenes, alkanes, NO2 and SO2 were carried out in the Port Arthur and Beaumont area using the SOF and mobile DOAS method and on May 7 similar measurements were carried out in Longview. During May 9 to 15, SOF and mobile extractive FTIR (meftir) measurements were carried out in the Fort Worth area, east of Eagle Mt lake in the Barnett shale area, complimented with canister sampling. With the meftir primarily methane, ethane, butane and CO was measured while a whole suite of VOC species will analyzed using the canisters. The measurements were carried by driving around in the Eagle lake mountain area looking for high methane concentrations. A large number of emission sources, including wells, compressor stations and treatment plants, were identified, and several of these were analyzed in detail carrying out tracer gas releases to quantify the emissions and canister sampling to get improved speciation of the VOC composition. In Figure 1 an example of routes traveled during the Fort Worth campaign are shown. May 16 and 17 SOF measurements were again carried out in Port Arthur and in particular, focus was put on training the UH-personnel to be able to carry out measurements on their own. During this period the meftir was used to identify emission plumes from the refineries and petrochemical industries, and in these plumes canister samples were taken. One nice canister measurements was carried out 5 km downwind of the industrial conglomerate in Beaumont at 3 AM to get stable atmosphere and down mixing of the emissions on the ground. On May 18 the intensive campaign ended and the meftir and mobile DOAS was dismantled from the UH SOF car and then packed and shipped back to Sweden.

2 The low intensity campaign, (Task 4) started may 19. The last weeks of May the weather was unfavorable for SOF measurements and hence no measurements were carried out. The wind mast was however moved to Mt Belvieu. Figure 1. Example of routes traveled with a mobile extractive FTIR during campaign measurements north west of the Fort Worth area. Data Collected (Include raw and refine data.) Below some figures illustrating the measurements, described above are shown with preliminary results.

3 Figure 2. Propene emission from the Kodak Eastman plant Longview on May 7. Here the propene emission corresponded to 300 kg/h and ethane 214 kg/h.

5 Figure 4. Emissions of methane (higher) and tracer gas (N2O) from a gas processing plant 8TDRW) in northern part of Eagle Mt Lake. Relatively high emissions were observed from a well tank; which was not observed the previous day. Here the ethane was about5% by mass and canisters were also taken. The average emission of methane corresponded to 277 kg/h.

Identify Problems or Issues Encountered and Proposed Solutions or Adjustments Since last report the project has gone as expected. Goals and Anticipated Issues for the Succeeding Reporting Period The intensive campaign ended May 20 and the the low intensity period started, were UH personnel will learn how to run SOF measurements by their own and produce emission data from Mt Belvieu. Additional Canister sampling will be carried out. Detailed Analysis of the Progress of the Task Order to Date (Discuss the Task Order schedule, progress being made toward goals of the Work Plan, explanation for any delays in completing tasks and/or project goals. Provide justification for any milestones completed more than one (1) month later than projected.) Task 1. Completed Task 2. Measurements completed,, analysis on going Task 3.
