EXCHANGE OF ATMOSPHERE IN CARGO OIL TANKS BY USING THE MIXING METHOD

This paper contains the results of an investigation into atmosphere exchange of cargo tanks by use of the mixing method. The investigation show that if certain requirements regarding tank inlet dimensions and arrangement are met the exchange process can, for practical use, be described with sufficient accuracy assuming the tank to be an ideal mixing chamber. It was found that the deviations from the theoretical process caused by inner tank structures and tank geometry were too small to be of practical importance. However, the investigations showed that a basic requirement for sufficient mixing is that the inlet jet penetrates down to the tank bottom.
