WebInside reactors during normal operation, fluid flow is the only significant way to remove process heat. Uneven fluid flow can impair performance. It can lead to hot spot formation, which can jeopardize process safety and catalyst life. ... The data shows that the operating WABT is reduced significantly. Fig. 23.8. Graph comparing WABT, before ... WebThe reactor can be operated as a continuous or batch process, when the hydrogenation reaction could generally take place at 250–350 °C and 3–10 MPa. The liquid product is separated from the gas phase in a separation tank, while the gas stream is fed to a gas purification unit before being recycled to the reactor.

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. ctc west school
