Cold-feed stabilization system

A typical cold-feed stabilization system is shown in Figure 2.4. The crude is being produced to a high-pressure separator operating at 1000 psig (7000 kPa). In this separator, the majority of the very light components, such as methane, can be removed without significant loss of the heavy components, while the bulk produced water is also removed from the crude. The crude oil is then flashed to the stabilizer...

The selection of equipment and the decision on a cold-feed versus a reflux stabilizer depend on several considerations. The availability of heat sources for the reboiler and streams for cooling the system influences the final decision. As usual, the economics of product recovery, capital investment, and operation costs will be major factors. 

For stabilizers with a reflux system, a feed heater may be required. If a feed heater is used, it is normally a shell-and-tube type that exchanges heat between the cold-feed and the hot bottom product, which is then cooled before going to storage.
