WebHydrocracker. Also known as: HCK, HCU, unicracker, VGO hydrocracker. In a refinery, the hydrocracker upgrades VGO through cracking while injecting hydrogen.This yields a high volume of high-quality diesel and kerosene product. This is in contrast to the FCC, which uses the same feed (VGO) but produces more and better-quality gasoline.. The … WebThe FCC is particularly valuable in a refinery that is trying to maximize gasoline production over residual fuel oil. ... Deactivated catalyst is drawn off the bottom of the reactor and is sent to a regenerator, where the coke is burned off by injecting heat and air. The cleaned (regenerated) catalyst is then sent back to the reactor, and the ...

WebThe first step is to hydrotreat the heavy naphtha feed to remove impurities such as sulfur and nitrogen that would be harmful for the reformer's platinum catalysts. This is done in a naphtha hydrotreater that may be considered part of the reformer, or a separate process unit. Next, the feed is sent through a series of 3-4 reactor vessels. can glass be used in the freezer

WebAn alkylation unit (alky) is one of the conversion processes used in petroleum refineries. It is used to convert isobutane and low-molecular-weight alkenes (primarily a mixture of propene and butene) into alkylate, a high octane gasoline component.
