This vessel can be used for several different liquids, one at a time.
It can also be used to blend different liquids.
The Vessel Receives liquid from an upstream source, which may be a tanker delivery or an upstream vessel
If then Delivers liquid downstream
It can stores the liquid at a controlled temperature, This may be above or below ambient depending on the liquid
The liquid is stirred, but the rate of stirring should ensure that energy is not wasted, by stopping the agitator or varying the speed.
Receiving can take place at the same time as delivering downstream, but this is not normally the case.
It is an Operator decision whether to all this.
The downstream process takes the material in batches, and there may be several downstream demands. These together may exceed the capacity of the discharge pump, so an arbitration system is required.
The vessel must be flushed with solvent to prevent cross contamination of different liquids.
