PROCESS FOR INCREASING THE CONCENTRATION OF NORMAL HYDROCARBONS IN A STREAM

Номер: US20210277316A1
Принадлежит:

A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. The non-normal paraffin rich stream is isomerized over a first isomerization catalyst to convert non-normal paraffins to normal paraffins and produce a first isomerization effluent stream. An iso-C4 stream is separated from the first isomerization effluent stream and isomerized over a second isomerization catalyst to convert iso-C4 hydrocarbons to normal C4 hydrocarbons and produce a second isomerization effluent stream. The normal paraffin rich stream, the normal paraffins in the first isomerization effluent stream and/or the second isomerization effluent stream may be fed to a steam cracker. 1. A process for increasing the concentration of normal paraffins in a feed stream comprising:separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream;isomerizing the non-normal paraffin rich stream over a first isomerization catalyst to convert non-normal paraffins to normal paraffins and produce a first isomerization effluent stream;separating an iso-C4 stream from said first isomerization effluent stream;isomerizing said iso-C4 stream over a second isomerization catalyst to convert iso-C4 hydrocarbons to normal C4 hydrocarbons and produce a second isomerization effluent stream; andfeeding said second isomerization effluent stream to a steam cracker.2. The process of further comprising separating a C4 stream from said first isomerization effluent stream and separating said C4 stream into said iso-C4 stream and a normal C4 stream.3. The process of further comprising feeding said normal C4 stream to said steam cracker.4. The process of further comprising feeding said normal C4 stream to the step of separating a normal paraffins stream from non-normal paraffins stream and desorbing normal paraffins from an adsorbent.5. The process of ...

Process for producing jet fuel with heat integration

Номер: US20240132790A1
Принадлежит: UOP LLC

A process isolates a liquid hydrocracked stream from a liquid hydroisomerized stream, so heat in the hydrocracked stream can be preserved. Preserving heat in the hydrocracked stream avoids having to reheat the hydrocracked stream before product fractionation. Particularly, kerosene in the hydrocracked stream is not cooled with the hydroisomerized stream and then reheated in fractionation to distill the kerosene range hydrocarbons from the diesel range hydrocarbons.
