<p>The fractionation and stripping equipment of a middle distillate catalytic dewaxing unit may be eliminated by integrating the catalytic dewaxing unit with a catalytic cracking unit. The light cycle oil sidestream (10) from the catalytic cracker fractionator (8) bypasses the sidestream stripper (38) and serves as the feed to the catalytic dewaxing unit (22). The dewaxed product is separated into a gasoline fraction (4) which is recycled for fractionation in the catalytic cracker fractionator and a fuel oil fraction (34) which is recycled to the catalytic cracker sidestream stripper for removal of light materials to produce a low pour point fuel oil (40).</p> |
