Question 3

Define Slopover

Answer 3

Any pockets of water, for example, from ill directed cooling lines that are interspersed within crude oil will be instantly heated to boiling point and expand to steam. The force of this expansion causes frothing of the top layers of the product which can then flow down the sides of the tank and into the bunded area.

Question 4

Define Boilover

Answer 4

over takes many hours to occur. A layer of water is located at bottom of tank mixed with sludge and waste. When the thermal layer (travelling at 0.3m to 1m an hour) reaches the bottom of the tank, the water is instantly vaporised (water to steam ratio of 1700:1).

This causes a piston effect which violently forces unburnt product up through the fire
