Introduction
How to Use AlPrg
AlPrg User Interface, AlPrg Windows.
Description of the AlPrg interface and AlPrg windows.
Plant Data
Aluminum Production
AlPrg determines on this page the aluminum production of your plant.
Consumptions
This AlPrg page calculates the consumptions of alumina, carbon anodes and alumina fluoride during electrolysis.
Alumina Feeding Page (1, 2, 3)
On this page you estimate the parameters of several alumina feeding phases to set the feeding frequency of the alumina feeding system.
Alumina Feeding Diagrams
On this interactive diagrams you change the feeding parameters and AlPrg draws the corresponding time behavior of cell parameters like voltage and temperature.
Interactive Alumina Feeding Webpage
On this interactive webpage you determine online the parameters of an alumina feeding phase.
Info about the Interactive Alumina Feeding Webpage
On this webpage you learn how to use the Interactive Alumina Feeding Webpage.
Electrolyte Properties
Electrolyte Properties Page
AlPrg calculates the bath properties in dependence of the bath composition and temperature.
Electrolyte Properties Diagrams
On this pages you find details about the dependence of bath properties on composition and temperature: Liquidus Temperature, Electrical Conductivity, Maximal Alumina Solubility, Densities, Total Vapor Pressure, Viscosities.
Interactive Electrolyte Properties Web Page
On this interactive webpage of this website you determine online the bath properties in dependence of the bath composition and temperature.
Cell Voltage
Cell Voltage Page
On this AlPrg page you determine the optimal cell voltage setting of your electrolytic cell.
Haupin Diagrams
The interactive Haupin diagrams draw the components of the cell voltage and of the energy balance. You change key cell values by mouse pointer dragging.
Cell Geometry Page
On this page you define the geometric layout of your electrolytic cell.
Cell Geometry Diagrams
This AlPrg page shows the dimensions of the cell layout.
Busbars Page
The busbar system is electrically divided into internal and external components concerning the energy balance.
Busbars Diagrams
These diagrams give an overview of the busbars layout of your cell.
Bath Voltage Page
The bath voltage is the sum of its electrochemical components (decomposition voltage and overvoltages) and ohmic components (due to the electrical bath resistance and gas bubbles).
Energy Balance Page
The electrolytic cell consumes energy to heat the starting materials and to produce aluminum. The difference of energy input and energy consumption is lost as heat.
