Abstract: The present invention relates to minimizing benzene, toluene, and an A9/A10 recycle loop in a zero benzene aromatics complex. More specifically, the present invention relates to a minimizing benzene, toluene, and an A9/A10 recycle loop in a zero benzene aromatics complex wherein the aromatic feed has a low methyl to phenyl ratio, and where the aromatic feed has a high methyl to phenyl ratio.

Abstract: A crude distillation and refining process and apparatus enables modular supply of the crude distillation column. Crude oil may be heated and then separated into only two liquid products in the crude distillation column. The separation between the light and heavy products may be controlled by the overhead product flow rate. Heat is recovered from an overhead stream and a bottoms stream by pre-heating the incoming crude oil stream by heat exchange with overhead stream and the bottoms stream. In an embodiment, a diesel-range distillate fraction may be condensed from an overhead stream in a first heat exchanger and a naphtha-range fraction may be condensed from the gas stream uncondensed by the first heat exchanger in a second heat exchanger.
