A delayed coker is a large machine that takes thick, heavy oil from the ground and turns it into lighter, more useful products like gasoline and diesel. It's like a big cooking pot that uses heat and pressure to break down the thick oil into smaller molecules. But it's a slow process - that's why it's called "delayed"!
Think of it like cooking a pot roast. You put the pot roast in the oven and let it cook for a long time, slowly breaking down the meat until it's tender and delicious. The delayed coker works the same way, slowly breaking down the oil into smaller molecules.
Once the oil is broken down, the different molecules are separated and sent to different places where they can be made into useful things like gasoline and diesel. It's like cutting up a cake and giving different slices to different people to enjoy.
Overall, the delayed coker is an important tool in making the things we need to go about our daily lives, like driving our cars or powering our homes.
