摘要： A tank for storing liquid products, particularly a large capacity tank (1), comprises a bottom (5), whose centre (6), is at a level below the level of the edge of the bottom. Drainage channels (7), consisting of a ramp (8), as floor with lateral plates (10), as sides, bring the undesirable materials to the edge of the tank where they can be drained out of the tank through drainage tubes.

摘要： An on-line, thermo-chemical process for the dewaxing of oil export pipelines with the aid of a Nitrogen Generating System is described, wherein the treating fluid to be employed as dewaxing fluid comprises: a) a solution of nitrogen salts activated by emulsified acetic acid and designed to yield nitrogen and heat, and b) a solvent, which is the pretroleum oil being produced. The dewaxing treatment is effected at the same time as the pretroleum oil is produced, this leading to great savings in costs and energy.

摘要： A cyclone leg sealing system is composed of one or more intermediate solids-accumulation chambers (21) delimited by two sealing valves (10 and 12) in series, the function of the valves being to prevent the back-flow of particulate material towards the inside of the separating cyclones in fluid catalytic cracking (FCC) processes, thereby ensuring the maximum efficiency of the separating effected by the cyclone.

摘要： There is disclosed a method and a device to allow a 'rigid' pig to pass into an undersea flow pipe in which a hollow flow-constricting device is in use. According to the invention the device is provided with a first pipe branch and a second pipe branch. The first pipe branch is provided with a hollow flow-constricting device in it and both first and second pipe branches are provided with shut-off valves, whereby the flow can be diverted to the second pipe branch thereby enabling a rigid pig to pass into such second pipe branch, when necessary.

摘要： This invention relates to a method for inverting the convex configuration of a liquid-product storage-tank bottom with a view to providing greater efficiency in the operations of removing the undesirable materials which normally accumulate in the tank bottom (5). A layer of material having, plastic properties, is placed over the conventional tank bottom (7), except for one part from the centre of the tank base to the edges. The material with plastic properties hardens over time, thus producing a new bottom (7) whose centre (11) is at a level below the level of the edges. The part over which material having plastic properties was not placed forms a flow gutter (9) which leads the liquids and sediments which have to be drained off to the edges.

摘要： A new form of construction for synthetic cables used for the anchoring of floating platforms in offshore oil production is described. A desirable requisite for this application is that the durability of the cable is not affected by deterioration of its strong core by virtue of the aggressive mechanical action of particles of the sea bed which might penetrate the cable and reach its core. For this purpose a layer (3) to protect the core (1) comprising a strip of polymer material placed in helical fashion which permits the passage of water and prevents the passage of particles of the sea bed towards the core (1) is placed between the cable core (1) and its outer braided protective layer (2).

摘要： The present invention relates to a system which makes use of a multiple reel on which groups of flexible lines supported by articulated structures (8, 9) are wound. The groups of flexible lines are interconnected at one end to flexible production and utility lines (4) emerging from the sea-bed and, at the other end, to connection blocks (10, 11) which may be connected to connection plates (15, 16, 17, 18) on at least one connection tower (13, 14) fixed to the vessel. As the connections are redundant, it is always possible to reposition one group of flexible lines while another group is connected, which gives the transfer system (2) total freedom of movement.

摘要： 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. Multiphase organic residues, petroleum residues, pure or in admixture in any amount, from chemical and pharmaceutical industries, paper and pulp industry, and mining industries can be processed in the inventive system. Besides, it is possible to recover phenols from foundry sands in the system and process described.
