| Abstract: | The corrosion protection by desahing and injection of water, corrosion inhibitor and fouling inhibitor for atmospheric - vacuum distillation unit processing marine high - TAN crude oils and the corrosion of overhead coolers of atmospheric and vacuun distillation towers are elaborated. The corrosion causes of tower overhead coolers are studied. The analysis concluded that th, main culprits of corrosion are the high salt content in the desalted high - TAN crude oil, which results in higher chorine ions in the overhead. Corresponding measures have been recommended for the mitigation of corrosion. |
