ABSTRACT
Once degassed and dehydrated-desalted, crude oil is pumped to gathering facilities to be stored in storage tanks. However, if there are any dissolved gases that belong to the light or the intermediate hydrocarbon groups (as was explained in Chap. 3), it will be necessary to remove these gases along with hydrogen sulfide (if present in the crude) before oil can be stored. This process is described as a “dual process” of both stabilizing and sweetening a crude oil.
