IPA: /haɪˈdrɒkər/
KK: /haɪˈdrɒkər/
A facility in chemical engineering where a process called hydrocracking occurs, which breaks down large hydrocarbon molecules into smaller, more useful ones, typically in the production of fuels.
The refinery's hydrocracker is essential for producing high-quality diesel fuel.
Hydrocracker → It is formed from "hydro-" (from Greek "hydor", meaning water) and "cracker" (from the verb "to crack", meaning to break or fracture). The term refers to a process that uses water in the breaking down of hydrocarbons in petroleum refining.
Think of 'water' ('hydro-') being used to 'break down' ('cracker') substances in oil refining — that's what hydrocracker means.
