Refinery vs cracker

WebIn refining, the FCC is the most common unit used to upgrade heavier distillation cuts to light products. The FCC takes VGO and similar intermediate streams and cracks them using heat in the presence of a catalyst. The primary product is FCC gasoline, which is used in gasoline product blending. WebThe difference between refining and cracking is that "refining" is present participle of refine and "cracking" is the thermal decomposition of a substance, especially that of crude …

WebThe most common cuts that are hydrotreated in a refinery include: light naphtha, heavy naphtha, jet fuel or kerosene, and diesel oils ( e.g., light and heavy coker diesel oil). This article focuses on the two main cuts: naphtha and diesel oil. The feed is first pressurized and mixed with the recycle and makeup hydrogen streams. WebMost refineries, therefore, add vacuum distillation and catalytic cracking, which adds one more level of complexity by reducing fuel oil by conversion to light distillates and middle …

However, both were considerably higher than the pre-coronavirus benchmark level of $10.80/b in 2024.

WebThe term cracking comes from the process of breaking up long hydrocarbon molecules into smaller, more useful molecules. The cracking process converts heavy straight run liquids into gasoline. There are multiple versions of the cracking process, and refiners use the process extensively. WebA higher cracking temperature (also referred to as severity) favors the production of ethene and benzene, whereas lower severity produces higher amounts of propene, C4-hydrocarbons and liquid products. The process also results in the slow deposition of coke, a form of carbon, on the reactor walls.
