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

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