2 Continuous Benzene-Specific Monitoring Werner R. Haag & Stephen Powell Ion Science RAECO Webinar, 15 Sept 2016

3 Benzene Continuous Monitoring Benzene- Specific Monitoring Werner Haag B.S. Chem., M.I.T. Ph.D. Chem., U. Tenn. Author of The PID Handbook Theory and Applications of Direct- Reading Photoionization Detectors

4 Benzene Industrial Exposure Oil refineries, Petrochemical Plants Storage, distribution & use of gasoline or benzene Offshore installations, Fracking operations Coke works Natural Gas condensate ABS Plastics manufacturing

5 Benzene in Fuels Exposure Limits for Various Fuels Chemical Benzene Diesel Fuel Jet Fuel Gasoline ACGIH TWA 0.5 ppm (Carcinogen) 12 ppm 30 ppm 300 ppm

6 Benzene in Fuels Mixture TWA Calculation TWA total = 1 f benzene + TWA benz f gasoline TWA gas.

7 Benzene in Gasoline

8 Benzene in Gasoline Typically 0.5 2% Difficult to measure selectively

9 Benzene EPA 2015 Final Rule Requires Benzene Fence-Line Monitoring at 12 to 24 locations every 2 weeks

10 Benzene Fence-line Monitoring

11 Benzene Fence-line Monitoring If rolling avg. over ppm, search for sources within 5 days, implement correction in 45 days. Annual sampling and analysis costs have been estimated at $40,000 to over $100,000 per year for biweekly sampling rule allows for less frequent carbon tube sampling if the plant can demonstrate a history of staying under the ppm annual limit, moving from bi-weekly to monthly, quarterly, semi-annually and finally annual sampling.

12 Tiger Select PID/Tube can measure: No Tube: Continuous ppb levels of VOCs for screening Insert Tube: Benzene-specific readings Single Point and 15-minute STEL

13 Benzene Monitoring TITAN Continuous Benzene- Specific Monitor

14 Benzene Specific Measurement Methods with DL near 0.5 ppm Method Time DL Cost Other Tubes: Manual min 0.5 ppm Single Point Tubes: Draeger CMS 10 min 0.2 ppm Single Point PID w/filter Tube 1-3 min 0.1 ppm $ Single Point Portable GC 5-10 min 0.1 ppm $$ Single Point Titan Separator 1 min 0.1 ppm $$$ Continuous Portable IR <1 min 2 ppm $$$ Continuous GC: On-Line 1 hour 0.01 ppm $$$$ Semi-Contin. GAC: Lab Analysis 1-10 days ppm $$$$ Off-site Portable IMS 1 min 0.01 ppm $$$$ Not Intr. Safe.

15 How TITAN works Temperature control AirSep filter PID Pump Pump Sample Control of temperature is critical therefore TITAN has two independent large heater ensures temperature an elevated temperature systems. inside the main A second heater accurately controls the temperature of the Benzene enclosure. separation (Air-Sep) filter tube.

16 How TITAN works AirSep filter PID Pump Valve Carbon Pump Sample TITAN continually draws a sample from the environment and through A portion of the air inside the TITAN is scrubbed by a carbon filter, and A sample the is instrument periodically taken to be used as carrier to separate benzene & then purge the filter tube. analysed for benzene content
