Heterogenous tank method

FIFO method

The FIFO (First In, First Out) method is suitable for representing pipeline segments.

Pipeline segments that have significant capacity must be represented in your plant model. AVEVA Production Accounting allows you to do this using a tank object with special property settings. For pipeline segments the fluid quantity is fixed (it does not fill and drain like a tank).

Such pipeline segment representations enable you cope with different plugs of material in the line in any one transaction. Each plug of material comes out in the same order as it went in. There is no mixing of material between the separate plugs.

The LIFO Tank Method permits you to model a last-in, first-out tank without mixing.
