Condition, Stream and Segment Subroutines

A stream is considered as a non-reactive medium for transferring matter to a reaction zone. It has constant temperature and pressure, and contains one or more phases of a certain composition, i.e., for each stream, temperature, pressure, and input amounts of phase constituents must be defined. Different sets of equilibrium conditions can be defined for the same system in different segments.
