Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed whereby dewaxing aids used to improved the separability of wax from hydrocarbon oils, preferably petroleum oil most preferably lube or transformer oils are themselves recovered from the wax and/or the dewaxed oil by means of the selective per-meation of the wax/dewaxed oil/dewaxing solvent through a semipermeable membrane with the retained, recovered de-waxing aid being recycled to the dewaxing process.  The dewaxing aid is recovered in an undegraded form, and is as effective in the dewaxing process as is fresh dewaxing aid.  Degraded dewaxing aid, if any, is passed through the membrane along with the wax, oil or dewaxing solvent and is thus not recovered for recycle.

Abstract: Case No. 7066.1 PROCESS FOR IMPROVING PRODUCT   YIELDS FROM DELAYED COKING Abstract of the Disclosure A delayed coking process in which the coker furnace feed is free of conventional heavy recycle.  Elimination of this material from the coker furnace feed produces, based on fresh feed to the process, increased liquids and decreased coke.  Coker furnace feed is initially combined with a diluent hydrocarbon having a lower boiling range than conventional heavy coker recycle and then transferred to the coker furnace.  The hydrocarbon diluent is much lower in coke-forming components than the heavy recycle which is normally combined with the fresh feed and fed to the coker furnace.

Abstract: Abstract of the Disclosure A plug container has a flanged, splined end which mates with a complemental end of a casing adapter member.  These two ends are secured to each other by a clamping mechanism which permits easy connecting and disconnecting of the two ends, thereby affording easy interchanging of different adapter members.  The plug container has a cavity with a diameter larger than the outer diameter of the plug to be retained in the cavity so that pressure equalization around the plug is maintained without an external bypass.  Pressure equalization is also maintained adjacent a cap which closes an end of the plug container.  This pressure equalization of the cap is achieved by one or more radial openings in an abutment wall of the cap.  The cap is sealed by a pressure-energized seal disposed in the interior surface of the housing into which the plug is threadedly connectible. Two manifold ports are disposed near the two ends of the cavity in which the plug is to be disposed.
