Abstract
Methods and systems for producing olefins and aromatics are provided. Methods can include removing silica from the coker naphtha feedstock to produce a first effluent, hydrogenating the first effluent to produce a second effluent, reacting the second effluent to produce a third effluent comprising aromatics, a fourth effluent comprising olefins, and a fifth effluent, separating the fourth effluent to produce a propylene product stream, an ethylene product stream, and a sixth effluent, recycling the sixth effluent by combining it with the second effluent.
