Structure of the Balancing System IBS

If compared with other analogous balancing systems, IBS is characterised by considerable freedom in structure formation. This flexibility of course does not mean a chaos - when defining the structure (configuration of the balance system for a specific problem), the user must obey certain rules described below. [Pg.469]

A node is the smallest unit to be balanced. Typical representatives of nodes are unit operations and reservoirs. One further often meets with joining or splitting of pipes - the node is then called mixer or splitter, respectively. It is often useless to balance single pieces of equipment, thus a node can consist of several apparatuses or even represent a larger operational unit or a whole plant. [Pg.469]

For better lucidity a set of many nodes is adequately divided into subsets [Pg.469]

Qualitatively, a stream can be characterised by the name of the medium which flows in it. From the balancing standpoint, the difference between mass [Pg.469]

As individual materials are considered such that considerably differ by their properties. It is not important where the material arises or where it flows to, because such information is stored in another way. Also unimportant are state variables (temperature, pressure) or other qualitative properties (such as density, sulphur content and the like), so far as these properties remain in certain limits. [Pg.470]
