Abstract
A process and apparatus provides for blending a heavy naphtha stream with a diesel stream to increase the yield of diesel. The diesel stream is recovered separately from a kerosene stream to leave the kerosene stream undiminished. The blended diesel provides a valuable composition.
Claims20
A process for separating hydroprocessed effluent comprising:
- separating a hydroprocessed effluent into a heavy naphtha stream having an initial boiling point temperature between about 121° C. (250° F.) and about 138° C. (280° F.), a kerosene stream having an initial boiling point temperature between about 138° C. (280° F.) and about 216° C. (420° F.) and a diesel stream having an initial boiling point temperature above 193° C. (380° F.);
- and
- blending the heavy naphtha stream with the diesel stream to provide a blended diesel stream.
A process for separating hydroprocessed effluent comprising:
- stripping a hydroprocessed effluent stream;
- separating a stripped hydroprocessed effluent into a heavy naphtha stream having an initial boiling point temperature between about 121° C. (250° F.) and about 138° C. (280° F.), a kerosene stream having an initial boiling point temperature between about 138° C. (280° F.) and about 216° C. (420° F.) and a diesel stream having an initial boiling point temperature between about 193° C. (380° F.) and about 227° C. (440° F.);
- and
- blending the heavy naphtha stream with the diesel stream to provide a blended diesel stream.
