determinations The semi automatic ASPHAN 02 apparatus offers several
benefits to the chemist and operator:
- Compact design;
easy operation
- Increase repeatability
and reproducibility
- Increases the
yield of the standard methods
- Decreases solvent
consumption as the solvents can be recovered
- Increases the safety level as the filtration step of the method is automatic without operator intervention or contact with solvents
The titration of asphaltenes content of petroleum products is generally determined in accordance with IP143 or NFT 60115 standards by precipitation with n-heptane. These methods are very time consuming and difficult to handle for samples from hydrotreatment or visbreaking processes.
Normally with such methods, determinations below 0.5% asphaltenes content are impossible. Also for determinations above 0.5%, the repeatability and reproducibility are very poor respectively 10% and 20%.
Our ASPHAN 02 analyzer, designed by TOTAL ELF Research, improves the characteristics of the IP143 and NFT 60115 methods in respect to:
- Repeatability around 5% for content> 2% Wt.
- Minimum determination level at 0.2 / 0.3% Wt
