<span style="font-family: arial,helvetica,sans-serif">Tall oil is an oxidizing oil and through reaction with oxygen of the atmosphere<br />
it dries and hardens (drying oil). Oxidation occurs in three phases: liquid, gum<br />
and solid. Tank cleaning should be therefore executed as soon as possible after discharge.</span></span></span><br />
