Integration of paraffin dehydrogenation with MOGD to minimize
compression and gas plant separation
摘要:
Disclosed is a method and apparatus for producing gasoline and distillate grade products which employs integrating catalytic (or thermal) dehydrogenation of paraffins with MOGD to minimize interstage compression and gas plant separation cost. The process cascades the product from a low temperature propane or butane dehydrogenation zone into a first catalytic reactor zone which operates at low pressure and contains zeolite oligomerization catalysts, where the low molecular weight olefins are reacted to primarily gasoline range materials. These gasoline range materials can then be pressurized to the pressure required for reacting to distillate in a second catalytic reactor zone operating at high pressure and containing zeolite oligomerization catalyst. The first catalytic reactor zone also acts to remove the olefins from the dehydrogenation reactor effluent to allow recycle of the unreacted paraffins.
