Patent ID: 6979755

Claim:
A process for manufacturing ethylene including a first remote site and a second developed, industrial site, wherein the first remote site forms a blend, comprising a Fischer-Tropsch syncrude having less than 1 ppm sulfur, to be used at the second developed, industrial site, the second developed, industrial site forming the ethylene, the process comprising: (a) receiving at the second developed, industrial site a blend comprising a Fischer-Tropsch syncrude having less than 1 ppm sulfur, a lighter naphtha fraction containing at least one C 5 –C 10 hydrocarbon and having a sulfur content of at least 1 ppm, and a heavier fraction having a sulfur content of less than 100 ppm, wherein the blend is made at the first remote site by a method comprising: (i) preparing a Fischer-Tropsch syncrude; (ii) preparing a lighter naphtha fraction containing at least one C 5 –C 10 hydrocarbon and having a sulfur content of at least 1 ppm; (iii) preparing a heavier fraction having a sulfur content of less than 100 ppm; and (iv) blending the Fischer-Tropsch syncrude with the lighter naphtha fraction and the heavier fraction; (b) converting the blend in a cracker unit to a product stream comprising ethylene; and (c) isolating ethylene from the product stream of the cracker unit.
