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.
Abstract:
GCI fuel compositions and methods of making them are described. The GCI fuel compositions comprises a fuel blend having an initial boiling point in a range of about 26° C. to about 38° C. and a final boiling point in a range of about 193° C. to less than 250° C., a density of about 0.72 kg/l to about 0.8 kg/l at 15° C., a research octane number of about 70 to about 85, and a cetane number of less than about 27, the fuel blend comprising a naphtha stream and a kerosene stream.

Abstract:
One exemplary embodiment can be a process for producing a chemical feedstock. The process can include passing a feed to a hydrotreatment zone, passing an effluent from the hydrotreatment zone to a fractionation zone, passing a stream including one or more C5-C25 hydrocarbons from the fractionation zone to a fluid catalytic cracking zone to obtain an another stream including one or more C6-C10 hydrocarbons, and passing the another stream to an adsorption zone for removing at least one heteroatom compound having a sulfur or a nitrogen atom.
