Abstract |
In this work, we studied the effects of the addition of mixtures of NaOH and functional aliphatic compounds on the dispersion of asphaltenes in a heavy oil. In this work, the functional groups of the organic compounds were alcohol, amine, and carboxylic acid. It was found that either NaOH or each organic compound did not show improved dispersion behavior of the asphaltenes by the addition of itself to the oil. However, when NaOH was mixed with the functional compounds, the mixture enhanced the dispersion of the asphaltenes in the oil. In addition, it was observed that the effects of the addition of NaOH-containing dispersant on the dispersion of the asphaltenes became stronger in the following order: the amine dispersant < carboxylic acid dispersant < alcohol dispersant. Furthermore, it was found that when the organic compound had a side chain, its dispersion property was improved. Thus, we proposed that NaOH-containing branched aliphatic compounds could be used as effective dispersants for the asphaltene in a heavy oil. |
