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.
