Research Regarding the Anticorosiv Protection of Atmospheric andVacuum Distillation Unit that Process Crude Oil
Journal Title: Tribology in Industry - Year 2011, Vol 33, Issue 4
Abstract
Due to high boiling temperature, organic acids are present in the warmer areas of metal equipment from atmospheric and vacuum distillation units and determine, increased corrosion processes in furnace tubes, transfer lines, metal equipment within the distillation columns etc. In order to protect the corrosion of metal equipment from atmospheric and vacuum distillation units, against acids, de authors researched solution which integrates corrosion inhibitors and selecting materials for equipment construction. For this purpose, we tested the inhibitor PET 1441, which has dialchilfosfat in his composition and inhibitor based on phosphate ester. In this case, to the metal surface forms a complex phosphorous that forms of high temperature and high fluid speed. In order to form the passive layer and to achieve a 90% protection, we initially insert a shock dose, and in order to ensure further protection there is used a dose of 20 ppm. The check of anticorrosion protection namely the inhibition efficiency is achieved by testing samples made from steel different.
