US Patent:

20110124931, May 26, 2011
Filed:

Nov 4, 2010
Appl. No.:

12/939808
Inventors:

Jianhua YAO - Bartlesville OK, US
Devadas PANJALA - Pearland TX, US
Eric W. VETTERS - Ponca City OK, US
Bruce RANDOLPH - Bartlesville OK, US
Assignee:

CONOCOPHILLIPS COMPANY - Houston TX
International Classification:

C10L 1/16
US Classification:

585 14
Abstract:

It has been discovered that the residence time of oils/fats in metal apparatus, particularly in the upstream of a hydrotreating unit, for example, a heat exchanger and/or a storage/feed tank, can impact significantly on corrosiveness of oils/fats in combination with and without conventional hydrocarbons. In addition, it is also found that the presence of hydrogen in the metal apparatus can also inhibit the corrosion rate of oils/fats.
