    Refining 3-2-1 per Time Magazine

    I always get a chuckle out of non-refiners trying to explain the refining business, but I can't say that the Time Magazine piece was too terrible. It touched on fundamentals of the crack-spread, which all refiners still use to some extent to gauge the overall health of industry margins, and...

    reforming catalyst contamination by silica

    Couple of tips for you: - monitor and manage the amount of antifoam used in upstream coker unit - install a silicon guard layer as top bed of your hydrotreater catalyst - measure silicon level in your feed on a routine basis - perform routine calculations of silicon loading, and pro-actively...

    coker feed

    I've seen refiners run topped crudes through a coker, but that is very different than whole range crude. Given that your coker was designed for SR resid, i agree with comments above that your equipment can handle whole range crude processing in any considerable amount. As also noted, i'd be...

    Refining process units monitoring

    Sheiko, MCP is Methyl-Cycle Pentane. The separation between this molecule and cyclohexane is an important one for optimizing reformer feed quality. MCP does not reform well, while cyclohexane does. Reactor exotherm is how much temperature gain occurs across your reactor. It's also known as...
