This application provides an HS scrubbing system, a column packed with an inert material, wherein an inert gas passes counter to a flow of a hydrotreated product containing HS through said column. There is also provided a method for scrubbing HS from a hydrotreated product, comprising providing a hydrotreated product containing HS; and passing the hydrotreated product over a column packed with an inert material, wherein an inert gas passed counter to a flow of the hydrotreated product.

Scrubbing hydrogen sulfide from hydrotreated product

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.
