Title: Process containing hf alkylation and selective hydrogenation
Inventor: HAMMERSCHAIMB HAROLD U
IPC: C07B61/00
Filed: 1988-11-03
Granted: 1991-11-19
Abstract: "A PROCESS CONTAINING HF ALKYLATION                     AND SELECTIVE HDYROGENATION"     ABSTRACT             Selective hydrogenation and HF alkylation are combined in a process that employs a multifunction alkylation feed stripper for removal of light ends from both the selective hydrogenation and alkylation operations. The process combines the effluent from the selective hydrogenation operation, an isobutane feed stream and a bottoms stream from the HF stripper in the alkylation feed stripper to provide a C4-plus bottoms stream that serves as the feed to the alkylation zone and a C3-minus overhead that can be recovered as fuel gas. Significant benefit is obtained from this process when processing a mixed olefin feed of C3/C4 hydrocarbons and recovering a high purity C3 product stream ahead of the selective hydrogenation zone.

Patent CA-1336135-C (CA)
Inventor: DUBE GHYSLAIN
IPC: C22B21/06
Filed: 1988-12-14
Granted: 1995-07-04
Abstract: The invention relates to a method and apparatus for treating non-ferrous metal drosses in order to recover the free metal contained therein.  The dross is heated by a plasma torch in a rotary furnace, preferably to a temperature above 800°C.  The plasma heating and rotary motion make it possible to recover metal from the dross without employing the conventional salt bath.  This means that the gases exiting the furnace can be treated more easily to remove pollutants and the solid residues can be discarded without risk of causing environmental pollution. By controlling the speed of rotation of the furnace, large dross lumps can be accommodated and so the conventional grinding and screening procedure of the dross can advantageously be eliminated.

Abstract: "FLAME ARRESTER HAVING DETONATION-ATTENUATING MEANS"     ABSTRACT OF THE DISCLOSURE         A flame arrester for a pipe line is provided comprising a detonation attenuator mounted within the arrester chamber between the quenching element and the backflash flame inlet.   The attenuator is generally cup-shaped, aligned with the inlet, of greater diameter than the inlet but of lesser diameter than the arrester chamber, and is positioned close to the inlet so as to circumscribe it.          The major portion of the high pressure central portion of a detonation wave generated by a backflash is received by the cup and reflected back into the pipe.  Some of the detonation wave passes around the cup and impinges on the arrester element - however it has been delayed sufficiently to ensure complete quenching of the flame front in the element.

Abstract: ABSTRACT OF THE DISCLOSURE         A method for recovering crystals from a crystal-containing slurry by supplying the slurry to a rotary vacuum filter while rotating a cylindrical filter medium thereof to effect a first stage filtration, washing and a second stage filtration, which method comprises conducting a sucking filtra-tion while pressurizing the slurry side so as to maintain such temperature and pressure that the filtrate of the rotary vacuum filter will not reach a condition of supersaturation, whereby stuffing of the filter medium due to deposition of crystals from the mother liquor with increase in the slurry viscosity is prevented and the recovery of the crystals are realized efficiently over a long period of time.  This method is suitable for recovering crude and purified terephthalic acid crystalline products and can be applied also for the recovery of general crystalline products, such as hydroquinone, resorcin and so on from slurries of them.
