BOPI 10 BR/2023 REPERTOIRE NUMERIQUE 13 (57) A novel polymers production process, often with tuels/chemicals as by-products. The invention consists of device, addition polymerization, condensation polymerization, process with piping, control and procedure. The device is a mechanical design to continuously remove solid deposit, conductive or not, on electrode surface. Besides overcoming the limitation of electrochemical polymer production where the products blocks the electrode from further operation, the device provides cheaper operation for electrometallurgy to harvest the valuable metals formed on electrode. The novel process allows retrofitting conventional polymer production process by replacing conventional reactor with electrochemical reactor, for low-cost rapid implementation. The novel reactions consist of addition reaction to produce addition polymers: and intermolecular reaction to produce classes of condensation polymers. The clusters of invention enable valuable polymers and chemicals to be produced at low cost for milder conditions and cheaper equipment, while allowing utilization of alternative feedstock especially chemical wastes, for further environmental and economic benefits.

NGWAFOR & PARTNERS Sarl, The House of Gideon, Golf/Bastos Quarters, Opposite The American Embassy, Entrance-Saint John Paul II Boulevard, P.O. Box 8211, YAOUNDE (CM) (57) Method for installing an elongated element (10), in a submarine duct (20), the submarine duct (20) having an entry port (21) and an exit port (22) located in outer liquid (OL) at a second depth, the method comprising the steps of : - introducing the elongated element (10) into the entry port (21), - introducing propelling liquid (PL) into the entry port (21), characterized in that the method comprises a step of sucking propelling liquid (PL) out of the exit port (22) of the duct (20) with an immerged suction pump (30) being operated at a predetermined suction pressure drop (APpump) of propelling liquid (PL) so that the predetermined suction pressure drop (APpUmp) applied to propelling liquid (PL) is smaller than a hydrostatic pressure (Phydro) of the outer liquid (OL) at the second depth.
