Apparatuses, systems and methods for separating highly pure unsaturated olefinic hydrocarbon stream with zero cooling water and or steam consumption, with minimum possible capital investment and uncompromised operational ease are disclosed herein from a mixture of hydrocarbon stream consisting of saturated and unsaturated hydrocarbons. Embodiments of the invention are directed to producing a hydrocarbon stream containing polymer, chemical grade ethylene, propylene, butylenes, isoprene, hexane stream which are of value in manufacturing chemicals, polymers, and rubbers. Embodiments of the process provided can be applied to concentrating ethylene, propylene, butylenes, cyclopentadiene, isoprene, 2 methyl butene-2, isopentane, hexene etc.

Process of separating unsaturated hydrocarbons from saturated hydrocarbons with low energy consumption

A process for the distillative separation of ethylbenzene from a mixture comprising ethylbenzene and at least one other C8 aromatic compound, comprising introducing a feed stream comprising said mixture into a first distillation column, introducing a first stream comprising a heavy solvent above the feed stream into the first distillation column, introducing an aqueous stream below the feed stream into the first distillation column.

Process for the enhanced separation of ethylbenzene

Apparatuses, systems and methods for producing Pips stream for manufacturing catalytic C5 hydrocarbon resins containing all the key reactive monomers that are already present in the C5 fraction of the pyrolysis gasoline, which is otherwise lost with the crude isoprene stream, are disclosed herein. Embodiments of the invention are directed to producing a hydrocarbon resin grade DCPD stream consisting of dimers and codimers of isoprene which are of value in manufacturing thermal hydrocarbon resins, either polymer grade isoprene and gasoline quality raffinate (free or sulfur and acetylenes) or a relatively small crude isoprene stream with maximum utilization of isoprene by moving some of the isoprene to a DCPD stream used to manufacture thermal hydrocarbon resins.

Process and apparatus for separating C5 di-olefins from pyrolysis gasoline

Apparatuses, systems and methods for separating heavy hydrocarbons from a solvent stream are disclosed. The heavy hydrocarbons and solvent can be recovered and processed further.

Methods and systems for the removal of heavy hydrocarbons

The claimed invention provides a technique wherein the two column system is combined into a single column. The light components are concentrated on the prefractionation side (feed side) of the column, where they are removed as an overhead top product. The middle boiling components are removed as an overhead product on the opposite side of dividing wall. For the same product specifications, top divided column requires substantially lower capital and operating cost than a conventional two-column system.
