Introduction

Describes the features of the AlWeb Interactive Webpages

Plant Data

Aluminum Production

On this page you determine the aluminum production in dependence of the number of electrolysis cells, the time period, current intensity and current efficiency.

CO₂, CO Production

This page shows the corresponding production of the gases carbon dioxide (CO₂) and carbon monoxide (CO).

Greenhouse Gases

On this page AlWeb investigates the production of the gases tetrafluoromethane (CF₄) and hexafluoroethane (C₂F₆) two very potent greenhouse gases.

Energy Consumption

This page shows the energy balance details of an electrolysis cell as an value overview and an Haupin type diagram.

Al₂O₃, AlF₃ Consumption

The electrolysis reaction produces aluminum from alumina ore (Al₂O₃). The sodium oxide (Na₂O) impurities of this feed material consume aluminum fluoride (AlF₃) to generate cryolite (Na₃AlF₃). This page describes this processes.

Anodes Consumption

This page shows the parameters how the electrolysis process consumes the carbon anodes.

Fluorides

This page is under construction.

Electrolyte Properties

On this page AlWeb calculates physical and chemical properties (like the liquidus temperature, the electrical conductivity, the alumina solubility, etc.) of the electrolyte in dependence of its composition and temperature.

Concentration Converter

On this page you determine the electrolyte composition for different systems (NaCry-AlF₃, NaF-AlF₃, Elements) and units (weight-, mole-percent).

Cell Voltage

On this page you determine the set values to operate the electrolytic cells optimally in an technical and economical way.

Web Pages without Database Connections

Alumina Feeding

On this page you determine the setting of the alumina pointfeeder to achieve a wanted time response of the alumina content of the electrolyte.

Anode Table Layout

On this page you study the behavior of the anode table during and anode change cycle period in dependece of the anode numbering scheme.
