Detrital apatite and zircon (U-Th)/He evidence for early formation and slow erosion of the Gamburtsev Mountains, East Antarctica

A process for the production motor fuel components from isoparaffins by dehydrogenation, oligomerization and saturation uses a single compressor to provide all feed and recycle requirements within the process arrangement. The single compressor can be employed for the integration of all three processes while surprisingly reducing equipment requirements throughout the integrated process arrangement. The compressor raises the effluent pressure of the effluent from the dehydrogenation zone to a level that eliminates the need for any additional compression for the recycle of hydrogen to the saturation zone, eliminates the need for refrigeration to recover butanes from the dehydrogenation zone effluent and allow an essentially complete elimination of heavies from the feed to the oligomerization reaction zone.
