Introduction
Intended audience
The present document is oriented to:
-
Model developers
-
Model users
-
System Integrators.
Scope
The scope of the present document is to describe the capabilities of the Inorganic demo, for the process modeling of a purification process based on multistage, counter-current acid washings.
Prerequisites
-
basic knowledge of process engineering and / or of inorganic processing.
-
know about the different roles involved with the lifecycle of solutions developed using the LIBPF™ enabling technology, see LIBPF™ Technology Introduction
Inorganic kernel
In LIBPF™ one kernel can support many process models, each as a different flowsheet type.
All the process models supported by a kernel share the same list of components and can use all LIBPF™ embedded types plus the custom types registered by the kernel itself.
Type list
The Inorganic kernel registers the following models, based on the built-in LIBPF™ FlowSheet type:
| Type | Description | options | Note |
|---|---|---|---|
| Attacco | Multi-stage attacks + washing | number of stages | |
| Stadio | Single attack stage | ||
| Inorganic | Purification process based on multistage, counter-current acid washings | default model type |
Additionally the following reaction types are defined, starting from the built-in ReactionYield type:
| Type | Description |
|---|---|
| ReactionSalt2 | Attack of Metal2 with Chemical1 |
| ReactionInert | Inert reaction |
| ReactionChemical4 | Inert attack with Chemical1 |
| ReactionMetal1Decomposition | Decomposition of the Metal1 water aggregate |
| ReactionMetal1 | Reacion of Metal1 with water to produce the aggregate |
| ReactionH2O2 | Elimination of hydrogen peroxide |
| ReactionChemical3 | Combination of Chemical3 with water |
Component list
The fluids to be processed are broken down in their constituents and represented as a mixture of basic components.
The components are defined using built-in LIBPF™ basic types.
More precisely the Inorganic kernel defines the following component list (click on the component type to jump to the reference documentation for the component):
| Type | Name | Description |
|---|---|---|
| purecomps::water | water | standard model for water |
| purecomps::H2 | hydrogen | standard model for hydrogen |
| Chemical1 | first attack chemical | custom component |
| Chemical2 | second attack chemical | custom component |
| Chemical4 | fourth attack chemical | custom component |
| Salt1 | first salt | custom component |
| Chemical3 | third attack chemical | custom component |
| Metal1 | first metal | custom component |
| Inert | inert component | custom component |
| Metal2 | second metal | custom component |
| Salt2 | second salt | custom component |
