Definitions
- Mixer
-
Mixes or combines multiple input streams into a single output stream. For each species the output stream has a flow equal to the sum of the flow of that species in each input stream. The output stream has a composition equal to the total flow of each species divided by the total flow of all species. Mixers can be as simple as a pipe tee or as complex as a stirred tank.
- Divider
-
Divides the input stream into multiple output streams, each with the same composition as the input stream, but with differing flow rates.
- Separator
-
Separates the input stream into multiple output streams, each with a different composition than the input stream. If the output streams have the same composition as the input stream, then the separator is a divider. The fraction of a given species in the input stream that exits in a given output stream is the split fraction for that species in that output stream.
- Split Fraction
-
The fraction of a given species in the input stream that exits in a given output stream is the split fraction for that species in that output stream. For separators with two output streams, the split fractions for a given species in the two output streams sum to 1. For separators with more than two output streams, the split fractions for a given species in all output streams sum to 1.
- Composition
- Composition is the same as the mole or mass fraction of each species in a stream. See What the Frac? for more details.
