    20 *               * Inlet(Ninlet) streams ....    at least one material stream
    21 *               * Outlet stream             ....        one material stream
     20*               * Hot Inlet streams ....        at least one Hot material stream
     21*               * Cold Inlet streams ....       at least one Cold material stream
     22*               * Hot Outlet streams  ....      one material stream for each Hot Inlet
     23*               * Cold Outlet streams  ....     one material stream for each Cold Inlet

    24 *               * Determines thermal and phase conditions of outlet stream
     26*               * Heat Transfer between multiple hot and cold streams.
