Internship - Behavior of Impurities During The
Il y a 7 mois
This is the opportunity to join Carmeuse for an exciting internship. During 6 months, within the Innovation department, you will have the opportunity to review the influence of limestone calcination and quicklime hydration steps on the final state of the impurities in the lime/hydrated lime.
**Purpose of the position**
Carmeuse produces and commercializes Ca (and Mg)-based products:
- Calcium hydroxide (Ca(OH)2) is a key products in Carmeuse’s portfolio.
Calcium hydroxide is obtained from a process in different steps:
- First, calcium carbonate (CaCO3) is extracted from the quarry;
- Then, the calcium carbonate is calcined in a kiln to obtain calcium oxide (CaO);
- Finally, the lime is converted into hydrated lime (Ca(OH)2) in a hydrator (reaction with water).
The different properties of the hydrates are:
- Chemical characteristics:
- Major impurities
- Minor impurities
- Heavy metal content
- Residual CO2- Physical characteristics
- Textural properties
- Density
- Particle size distribution- Properties
- Flowability
- Solubility
- Reactivity
- Performance test**Work Description**
The scope of the project is to study, with different chemical analyses (to identify), the impurity state in limestone, quicklime and hydrated lime.
The aim is also to understand how the state of the impurities is influenced by other impurities or by process parameters. A key element to identify is the oxidative level of each element at each phase.
Concretely, after a scientific bibliographic review, the work will continue with experimental reactions at laboratory scale. Product from the plant, sampled by the student and Carmeuse supervisor, will be compared with samples produced at lab in specific conditions. The main part will be to validate the right method to use to correctly measure the element.
