| Hydrodesulphurisation (HDS) of cracked gasoline is vital for the production of clean fuels. Along with sulphur removal, however, olefin saturation occurs. In order to design a gasoline HDS reactor, it is important to know the olefin content and the S content. Knowing the olefin content is key to achieving a proper design, as olefin saturation largely sets the heat release and hydrogen consumption that will be experienced. Measuring the olefin content of cracked gasoline is not as simple as it seems. There are a number of analytical methods with varying degrees of accuracy and relevance for olefin measurement in cracked gasoline. This study examines several of the more common methods used in the industry, and compares their performance with a sample of full range FCC gasoline. A case is made that the Bromine Number is the best measurement to use as the basis for a reactor design. |
