Submodules

idaes.property_models.examples.saponification_reactions module

Example property package for the saponification of Ethyl Acetate with NaOH Assumes dilute solutions with properties of H2O.

class idaes.property_models.examples.saponification_reactions.ReactionBlock(*args, **kwargs)

Parameters:

• rule (function) – A rule function or None. Default rule calls build().
• concrete (bool) – If True, make this a toplevel model. Default - False.
• ctype (str) – Pyomo ctype of the block. Default - “Block”
• default (dict) –

  Default ProcessBlockData config

  Keys

  parameters

  A reference to an instance of the Reaction Parameter Block associated with this property package.

  state_block

  A reference to an instance of a StateBlock with which this reaction block should be associated.

  has_equilibrium

  Flag indicating whether equilibrium constraints should be constructed in this reaction block, default - True. Valid values: { True - ReactionBlock should enforce equilibrium constraints, False - ReactionBlock should not enforce equilibrium constraints.}

• initialize (dict) – ProcessBlockData config for individual elements. Keys are BlockData indexes and values are dictionaries described under the “default” argument above.
• idx_map (function) – Function to take the index of a BlockData element and return the index in the initialize dict from which to read arguments. This can be provided to overide the default behavior of matching the BlockData index exactly to the index in initialize.

Returns:

(ReactionBlock) New instance
