Investigates storage tank emissions that may result from landing and subsequently refloating a floating roof.

The existing emission factors for floating-roof tanks are based on the assumption that the floating roof is continuously floating on the stored stock liquid.

Additional emissions may occur, however, if the tank is emptied such that the floating roof is no longer floating. This study sought to quantify these floating-roof landing loss emissions. See more
