Definitions
- a second embodiment of the invention is a process for converting a naphtha feedstream, comprising fractionating the naphtha feedstream to generate a naphtha overhead stream comprising C4 and lighter hydrocarbons, and a naphtha bottoms stream comprising C5+ hydrocarbons; hydrotreating the naphtha bottoms stream to generate a hydrogenated stream having a reduced acetylene, diolefms, sulfur and nitrogen content; passing the hydrogenated stream to a separation unit to generate an extract stream enriched in normal hydrocarbons and a raffinate stream; passing the extract stream to a extraction separation system to generate an extract overhead stream comprising nC5 and nC6 compounds, an extract intermediate stream comprising nC7 to nCl 1 compounds, and an extract bottoms stream comprising desorbent; passing the raffinate stream to
- An embodiment of the invention is one, any or all of prior embodiments in this paragraph up through the second embodiment in this paragraph further comprising passing a portion of the extract overhead stream to an isomerization unit to generate an isomerized stream comprising C5 and C6 compounds.
- An embodiment of the invention is one, any or all of prior embodiments in this paragraph up through the second embodiment in this paragraph further comprising passing the isomerized stream to the separation unit.
- the present embodiment provides flexibility in the processing of a hydrocarbon feedstream for the production of light olefins and/or aromatics.
- the process as shown in Figure 1, includes passing a treated hydrocarbon stream 8 to a separation unit 10.
- the separation unit 10 generates an extract stream 12 enriched in normal hydrocarbons, and a raffinate stream 14 having a reduced normal hydrocarbon content.
- the extract stream 12 is passed to an extract separation system 20 to generate an extract overhead stream 22.
- the extract separation system 20 can also generate an extract intermediate stream 24, and an extract bottoms stream 26.
- Normal components in the hydrocarbon stream are more readily cracked to form light olefins than non-normal components.
- the normal components are also more difficult to reform to aromatics than non-normal components.
- the separation of normal and non-normal components, combined with passing the different stream to appropriate downstream processing units improves flexibility and the economics of cracking and reforming naphtha.
- the ability to convert normal components to non-normal components allows the shifting of hydrocarbon components from the stream fed to a cracking unit to a stream for generating gasoline components.
- a naphtha feedstream comprises many hydrocarbon components, and is often passed to a cracking unit for the production of light olefins.
- the composition of a naphtha stream includes components that do not crack well to light olefins and this leads to further processing.
- a naphtha feedstream also include useful hydrocarbons for converting to aromatics.
- the present embodiment seeks to separate a naphtha feedstream to increase the yields and efficiencies of naphtha cracking units and reforming units.
- a naphtha feedstream will typically comprise hydrocarbons in the C4 to C 11 range.
- the adsorption separation unit 10 will therefore utilize an appropriate desorbent, which is normally outside this range.
- One desorbent that works for a light naphtha having components in the C4 to CI 1 range is n-C12.
- a preferred embodiment is for the integration of a separation system, an isomerization system, and a catalytic reforming process into an integrated refinery-petroleum operation.
- the process provides for shifting hydrocarbons between a cracking process to generate light olefins, and a reforming process for generating aromatics.
- the extract separation system, or the raffinate separation system will utilize a divided wall column to produce three separate streams. This will save on capital and operating costs. This process will allow flexibility in the area of gasoline production, through shifting of hydrocarbon components, and in particular C5 and C6 components in a naphtha feedstream, from a cracking stream to a reforming stream, or for directing to a gasoline blending pool.
