ABSTRACT
As already noted, a petroleum refinery is a group of integrated unit processes (Figure 8-1), the use and combination of which are dependent upon the character of the crude oil (Speight, 1991; McKetta, 1992; Gray, 1994). Nevertheless, a refinery produces a variety of products from these processes that often require stabilization though hydrotreating. In this sense, the term stabilization refers to production of a product that, to all intents and purposes, does not undergo any further reaction when exposed to the air.
