112th LDAR Symposium May 15-16, 2011 New Orleans, LA Utilizing LDAR Data to Lower (Actual and Reported) Emissions at Your FacilityGreg WilsonLDAR CoordinatorLyondellBasell Houston RefineryShane KlingChemical EngineerEnvironmental intellect
2LyondellBasell-Houston Refinery Located in Houston, Texas372,000+ componentsin LeakDAS databaseAbout 350,000 annualLDAR monitoring events
3Where to Focus on Reducing Emissions? A substantial percentage of annual reported emissions are from two sourcesUnmonitored (not required) componentsMisidentified componentsIdentification of these sources can allow a targeted approach to sizable reductions
4What’s What?Unmonitored components are ones for which no regulatory requirement existsMisidentified components are those in your facility that are being calculated using an emissions factor for another class of component. For example, in accurately referring to a component class of “Other” rather than “Valve.”
5Unmonitored Components Light liquid (LL) and gas/vapor (GV) connectors that have no regulatory require-ment can contribute a great deal to calculated emissions and are the easiest targetsWhich ones?Built-in reports within the software (e.g., LeakDAS)Homegrown tools to examine the data in order to make informed decisions
6Unmonitored Components, cont. LDAR software can assist in spotting trends or areas that you can address; i.e. “Top 50 Emitters” ReportHomegrown systems can be customized to your needs. We use a program that reports the Top 1000 emitters every day
7Unmonitored Components, cont. Using this data, analysis of specific areas or units for reduction opportunity can maximize effectiveness.Voluntary monitoring of a subset of non-regulatory components can significantly reduce reported emissions in a large or small facility.
8Unmonitored Components, cont. Using refinery factors, a connector that is unmonitored and has no valid monitoring has an emissions rate equal to one that was monitored and left unrepaired at 1,026 ppmStated another way, monitoring 10,000 connectors and achieving a net of 50 ppm will reduce VOC emissions by about 22 TPY for a refinery.
9Unmonitored Components, cont. Using SOCMI factors for the same 10,000 components and the same 50 ppm net reading as an average, would result in a reduction of about 167 TPY for the facility.A 1 wt% averagebenzene concentrationfor these componentswould result in greater than1.6 TPY reduction in reported BZ emissions.
10Can You Keep It That Way?After a period of time, a single monitoring result is no longer valid. To maintain a reduction, these previously unmonitored components must become part of your schedule. Budget for them!Make a habit of looking for “bad actors” within your program and fix them!Create a “Voluntary Rule” and apply it to the ones you’ve selected
11Other Ways to Reduce Emissions from Unmonitored Components? Consider routing non-regulatory connectors with monthly/quarterly valve monitoring.Incorporate non-regulatory monitoring as fill-in work when possible.Got fin-fan plugs?Non-regulatory connectors are DTM? SKIP THEM!!!Remove the voluntary rule across the board before the end of the year. You’re finished!
12Misidentified Components Incorrect class description, stream speciation and other issues with the information in the data are prime culpritsCorrect identification and field verification are key to having an accurate reporting foundation.A key is to know where and what the components are in the field and on the P&ID’s
13How Can Smart P&IDs Help Eliminate Misidentified Components? Integrate refinery stream speciation into individual LDAR components on smart P&IDExport P&ID data into LeakDAS (Stream, Chemical State, Component ID, P&ID No., etc.)Use marked-up P&IDs with tag numbers labeled to expedite LDAR inventory processMaintain P&ID with LDAR tags to account for regulated equipmentLong-term: update LeakDAS database automatically when smart P&ID is updated during MOC process
14What is a “Smart P&ID?” (nothing more than a P&ID with underlying data)
15Eliminating Misidentified Components with Smart P&IDs
16Apply Stream Speciation to LDAR Equipment in sP&ID Stream speciation data is exported from Aspen HYSYS into MS Excel formatSpeciation data was importedinto sP&ID using Ei’s softwareStream assignments wereintegrated into smart P&IDsfor pipes, valves, etc.Ei’s software generated LDAR determinations for all streams and all equipment in smart P&IDs
17Apply Stream Speciation to LDAR Equipment in smart P&IDs
18Import Smart P&ID data into LeakDAS Data is exported from smart P&IDs into LeakDAS through the following steps:Data for LDAR equipment is stored in an underlying P&ID database within AutoCAD P&IDTMNine P&ID data fields, including ‘Stream’, ‘Chemical State’, ‘Component ID’, ‘P&ID No. have been utilizedData is exported from sP&IDs into a .csv format file with data columns that match LeakDAS database structureEi’s data was imported into LeakDAS to ‘Quarantine’Data is processed from ‘Quarantine’ into LeakDAS and then available for download into LeakDAS MobileNote: any future changes to LeakDAS data can be exported to update the smart P&IDs (e.g., LDAR Tag No.)
19Export P&ID data into LeakDAS (Stream, Chemical State, Component ID, P&ID No., etc.)
20Long-Term: Connect LeakDAS with Smart P&IDs Future efforts are being planned to link together smart P&IDs and LeakDAS – when the P&ID is changed during MOC, updates will be sent to LeakDAS automaticallyAdditional environmental compliance benefits for smart P&ID implementation:Component counts for permitting project emissionsMarked-up P&IDs with LDAR tag numbers labeledImproved LDAR inventory performance
21ConclusionsIf you can maintain a program that allows you to finish each period without burning the “midnight oil,” you can make a difference by monitoring voluntary components.Accurate counts, classifications and speciation of components will enhance your ability to manage your program.LDAR programs are meant to REDUCE EMISSIONS! These processes can help achieve that goal.
22ConclusionsSmart P&IDs can help eliminate misidentified components and ensure accurate speciation.The ability to manage change through data-driven processes can keep your LDAR program evergreen.
