초록 ▼

A high-flux membrane, especially a sieving membrane, is used to separate a naphtha feedstock into a retentate fraction having a reduced concentration of normal paraffins for an enhanced reforming feed and a permeate fraction having an increased concentration of normal paraffins for an enhanced crack

대표청구항 ▼

The invention claimed is: 1. An integrated naphtha cracker and naphtha reformer system comprising: a. a naphtha supply conduit adapted to supply naphtha feedstock; b. a membrane separator having at least one inlet and containing a selectively permeable membrane having a permeate side and a retentate side, said membrane having a C6 Permeate Flow Index of at least 0.01 and a C6 Permeate Flow Ratio of at least 1.25:1, said membrane separator adapted to provide a permeate on the permeate side that is enriched in normal paraffins as compared to the naphtha feedstock; c. a naphtha cracker adapted to produce olefin in fluid communication with the permeate side of the membrane; and d. a naphtha reformer adapted to provide a reformate in fluid communication with the retentate side of the membrane. 2. The system of claim 1 in which the membrane is a sieving membrane. 3. The system of claim 2 in which the sieving membrane has a C6 Permeate Flow Index of at least 0.02 and a C6 Permeate Flow Ratio of at least 1.35:1 to 6:1. 4. The system of claim 1 in which intermediate and in fluid flow communication with the membrane separator and the reformer is a hydrotreater adapted to remove sulfur components. 5. An integrated process for converting naphtha feedstock containing normal and non-normal paraffins to olefins and reformate comprising: a. contacting at said feedstock with a retentate-side of a selectively permeable membrane having a C6 Permeate Flow Index of at least 0.01 and a C6 Permeate Flow Ratio of at least 1.25:1 under conditions including sufficient membrane surface area and pressure differential across the membrane to provide a retentate fraction that has a reduced concentration of normal paraffins, and to provide across the membrane at a permeate-side, a permeate fraction having an increased concentration of normal paraffins; b. cracking at least a portion of the permeate fraction under cracking conditions to provide an olefin-containing cracker product; and c. reforming at least a portion of the retentate fraction under reforming conditions to provide an aromatic-containing reformate. 6. The process of claim 5 in which the membrane is a sieving membrane. 7. The process of claim 6 in which the sieving membrane has a C6 Permeate Flow Index of at least 0.02 and a C6 Permeate Flow Ratio of at least 1.35:1 to 6:1. 8. The process of claim 5 wherein the naphtha feedstock contains sulfur component and the retentate fraction is subjected to hydrotreating under hydrotreating conditions to remove sulfur component therefrom prior to reforming. 9. The process of claim 8 wherein the sulfur component permeates the sieving membrane and the concentration of sulfur component in the permeate fraction is greater than the concentration of sulfur component in the retentate fraction. 10. The process of claim 5 wherein the concentration of normal paraffin in the permeate fraction is between 40 and 80 mass-%.
