Blending is the last process in the refining that mixes the optimal combination of components (among various petroleum streams) to produce the final finished product. The main purposes of crude oil blending are to optimize commercial value, to upgrade or reduce oil consumption to meet specifications, and to facilitate oil movement. End product example: LPG, gasoline, diesel etc

Conversion convert one hydrocarbon stream into another by changing molecule size and structure. The objective is to shift the yield of the refinery away from less valuable products (e.g., residual fuel oil, LPG) and toward more valuable ones (e.g., gasoline, diesel). ]]> 2021-10-13 02:51:28 UTC https://padlet.com/arina_sauki/CPE656_W1_G2_T1/wish/1812661517 https://padlet.com/arina_sauki/CPE656_W1_G2_T1/wish/1812666446 Breaking large molecules into smaller ones (cracking), joining small molecules into larger ones, or changing the shape of molecules without changing overall size.

These fuels can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. ]]> 2021-10-13 03:07:39 UTC https://padlet.com/arina_sauki/CPE656_W1_G2_T1/wish/1812697463 https://padlet.com/arina_sauki/CPE656_W1_G2_T1/wish/1812701302 -Farisa
There are 3 types of blending process:

• In-line through a manifold system: The in-line blending is accomplished by injecting proportionate amounts of each component into the main where turbulence promotes thorough mixing.
• Batch blending in tanks: All component is fed into mixing and stirred until a homogeneous blend is achieved
• Onboard blending into marine vessels: Mixing operation of two products should only be undertaken whilst the ship is within port limits. The physical blending on board of bulk liquid products during a sea voyage to create new products is prohibited.
