1x1 Pass Through
1x1 Pass Through Useful for representing
continuous processing steps that are not
explicitly available in the current version of ProDesigner. It can handle simple pass-through
steps.
1x1 Reaction
Useful to represent continuous processing steps
that are not explicitly available in the current
version of Pro-Designer. It can simulate material
transformations (reaction) and / or simple pass
through steps.
1x2 Reaction / Separation
Useful for representing continuous processing
steps that are not explicitly available in the
current version of Pro-Designer. It can simulate
material transformations (reaction) and / or
simple pass through steps as well as flow or
component splitting.
2x2 Reaction / Separation
Useful for representing continuous processing
steps that are not explicitly available in the
current version of Pro-Designer. It can simulate
material transformations (reaction) and / or
simple pass through steps as well as flow or
component splitting.
3x2 Reaction / Separation
Useful for representing continuous processing
steps that are not explicitly available in the
current version of Pro-Designer. It can simulate
material transformations (reaction) and / or
simple pass through steps as well as flow or
component splitting.
5x2 Reaction / Separation
Useful for representing continuous processing
steps that are not explicitly available in the
current version of Pro-Designer. It can simulate
material transformations (reaction) and / or
simple pass through steps as well as flow or
component splitting.
1x1
Useful for representing batch processing steps
that are not explicitly available in the current
version of Pro-Designer.
3x3
Useful for representing batch processing steps
that are not explicitly available in the current
version of Pro-Designer.

5x5
Useful for representing batch processing steps
that are not explicitly available in the current
version of Pro-Designer.
10x10
Useful for representing batch processing steps
that are not explicitly available in the current
version of Pro-Designer.
Pass Through *
Useful in simulating processing steps of discrete
entities that involve no physico-chemical
transformation, yet they incur some cost (e.g.
inspection, weighing, etc.).
Pass Through / Bulk
Separation *
Useful in simulating processing steps of discrete
entities that involve no physico-chemical
transformation, yet they incur some cost (e.g.
inspection, weighing, etc.). It can simulate a
simple pass through of discrete entities and
component splitting.
Bulk to Discrete *
Converts flow of bulk material into flow of
discrete entities.
Discrete to Bulk *
Converts flow of discrete entities into flow of bulk
material.
Flow
Useful for expressing design specification
constraints that will set a stream’s flow. User
must select an input stream whose flow is to be
adjusted to achieve the design goal.
Composition
Useful for expressing design specification
constraints that will set a stream’s composition.
User must select an input stream whose flow is
to be adjusted to achieve the design goal.
Temperature
Useful for expressing design specification
constraints that will set a stream’s temperature.
User must select an input stream whose flow or
temperature is to be adjusted to achieve the
design goal.
