  • Patent number: 7727377
    Abstract: A system 100 is described for the treatment of multiphase residues having unlimited content of water, oil and solids to obtain hydrocarbons and other products, said system comprising multiphase residue feed system 10, inert gas system 20 and reduced pressure system 30, tubular reactor 40 provided with three heating zones Z-1, Z-2 and Z-3 with a temperature gradient and transportation helicoid 42 to displace the residue mass throughout the reaction zones, the hydrocarbon products and water being collected in a system 60 of condensers 61, 62 and 63 linked to a system 70 of bubbling vessels 71, 72 and 73, reactor 40 being operated in the sealed mode and being provided with a multiphase residue inlet 43 and exit 44 of solid product. The solid product is collected in a system 50 comprising upper valve 51 and lower valve 52, and intermediate silo 53 and then directed to post-treatment system 90 for activation aiming at industrial utilization. The process using the system 100 of the invention is also described.

  • Publication number: 20050000032
    Abstract: “EQUIPMENT AND PROCESS TO FINISH FABRICS IN GENERAL” comprised of a bath tank (3) that may be filled with a treatment liquid such as a bleacher, dyeing agent or washing liquid that can be adjusted to a fabric (T) conveyance means. In the circulation direction, at the rear of the bath tank (3) exit, there are squeezing rolls (6) or suction devices, to which the fabric to be squeezed or suctioned from the bath liquid is conveyed. After that there are guides on which the humid fabric may be placed on a return belt. (7A). In the latter, the fabric circulates more slowly so that it is accumulatively placed on the belt (7A). At the end of the return belt exit (7A), additional guides are connected (11) to allow the fabric (T) to return to the bath tank (3) or to allow the bath to be ended and the fabric to be taken to the plaiter unit (8).
