API s CELE Committee on Evaporative Loss Estimation GEORGE L. MOROVICH

Session Goals CELE Structure Standards and Process Research and Standards development Know where to find resources you need

Current Situation Tank emissions receive much attention AST Owners need to: know where to secure information for estimating emissions inventory have accurate information for regulators and public respond to ever increasing requirements to document various technologies and operational requirements

Topics Committee on Evaporation Loss Estimation Committee Structure Committee Make Up Environmental Drivers Current Projects Path Forward

CELE Benefits Your contact source for AST Emission information Maximum input to Standards Coordination between industry and regulation Response to environmental issues Continuous improvement Incorporation of latest technologies Credibility and improved defensibility Global leadership

API Committee on Petroleum Measurement COPM Committee on Petroleum Measurements CELE Committee Evaporation Loss Estimation COMA Committee on Measurement Accountability COMQ Committee on Measurement Quality COGFM Committee on Gas Fluids Measurement COLM Committee on Liquid Measurement COMET Committee on Measurement Education and Training CPMA Committee on Production Measurement and Allocation You know the who to contact for a question

API Staff Paula Watkins Committee Make Up Chair- Terri Stillwell Magellan Consultant Rob Ferry TGB Partnership Petroleum Company Representatives CELE AST Equipment Manufactures Energy Institute Europe US EPA Instrumentation Manufacturers Maximum Input

Drivers Regulators exploring new monitoring tools Looking at short term emissions Questioning estimation methodologies Desire to address maintenance and other nonroutine emissions Environmental Health and Safety Issues Development of new technologies Improve response to environmental issues

Standard Publications Update API Manual of Petroleum Measurement Standards (MPMS) Chapter 19 Chapter 19.1 Evaporative Loss from Fixed-Roof Tanks Chapter 19.2 Evaporative Loss from Floating-Roof Tanks Chapter 19.3 Testing Protocols Chapter 19.4 Evaporative Loss Reference Information and Speciation Methodology for Chapters 19.1 & 19.2 (including solar factors) Chapter 19.5 Atmospheric hydrocarbon emissions from marine vessel transfer operations Continuous improvement in resources

Research and Reports Technical Report 2567 Evaporative Loss from Floating Roof Landings Technical Report 2568 Evaporative Loss from the Cleaning of Storage Tanks Annex I of Chapter 19.4 (new edition under publication) Storage Tank Liquid Bulk, Liquid Surface, and Vapor Space Temperatures Technical Report 2569 Evaporative Loss from Closedvent Internal Floating-roof Storage Tanks

Technical Report for Tank Roof Landings Heel Configurations Determine the Saturation Factor Full Heel Partial Heel Drain Dry

Tank Liquid Surface Temperature Emissions are driven by liquid surface temperature EFRTs have higher liquid surface temperatures. A fixed roof shades the floating roof.

Tank Liquid Surface Temperature Study of 4 150 ASTs (2 ADRT / 2EFRT) 2 Dhahran, Saudi Arabia / 2 Edmonton Alberta

Current Projects Crude Oil Flashing Emissions and E&P Tanks Vertical ladder / Gauge well emissions Identify future needs for technical reports or standards Support other committees and task forces Marine vessel loading Improve your defense
