Process for inhibiting the deposit of paraffins in crude oils and petroleum sections utilizing N-substituted succinimide ethers |
摘要 |
A process for inhibiting the deposit of paraffins in crude oils and petroleum fractions incorporating additives of the family of N-substituted succinimide ethers. The additives according to the invention make it possible, on the one hand, to maintain in dispersion the whole range of paraffins improving the flowing properties of crude oils and, on the other, to prevent the deposit of the heavier paraffins on the walls. Therefore, the process is effective during both the storage and the transportation of crude petroleum.
