Definitions

  • So-called sludge is the deposit of crude oil and its heavy fractions on storage units. This sludge causes many troubles in the handling of crude oil whether in pipelines, storage tanks, or in refineries. It leads to block pipelines, especially in cold weather and also causes blockage of the nozzles of burners.
  • Petroleum sludge consist of organic materials such as paraffin waxes, asphaltenes, resinous materials and other materials such as cotton pieces. Beside the organic materials, there are inorganic substances as dust, scales and water.
  • the factors controlling the sludge formation in petroleum storage units are oxidation, - ⁇ iectrostatic charging, coagulation, volatility and the precipitation of wax and solid components.
  • Comi ⁇ ntional methods are mainly manual methods as labors used to break down the sludge bonds (after opening the tank and leaving it to be gas free) then dump all the sludge inside pits causing many environmental problems besides loss of huge quantities of crude oil that can be recovered and sold by our new method or mechanical method where moving the sludge from tank to another that leads to transporting and spreading the problem without presenting a final solution.
  • the main target of the invention is to reclaim and recover the hydrocarbons from the sludge accumulated in oil storage structures ( tank, tankers and gas separators) into crude oil conformable to specs , reducing the economic losses, also to expand the holding capacity of these storage units by removing the sludge and taking use of the spaces it occupy in these units.
  • thermo-chemical method because the chemical introduced in the sludge to break the sludge into three components (hydrocarbon, water and inorganic sediments).
  • hydrocarbon, water and inorganic sediments all the hydrocarbon contents of sludge will be provided with a permanent floating ability for dissolving into crude oil.
  • Thermal in order to achieve the optimum working of the chemical in the sludge within an acceptable time.
  • the sludge is stirred " and v ⁇ alme ⁇ l ⁇ pTF ⁇ Ft ⁇ heat exchangers are temporarily piped to storage tanks, So by elevating the temperature of the mixture, the sludge will be pumped and liquefied, then at 50-60 0 C the chemical will start to act as a surfactant.

Abstract

La présente invention concerne la récupération de boues de pétroles à partir de pétrole brut dans des unités d'entreposage, ce qui comprend : l'aspiration du pétrole brut des unités pour être chauffé à l’extérieur par un échange de chaleur, l’ajout de produits chimiques pour dissoudre la boue, le pompage du pétrole brut réchauffé dans l'unité pour chauffer le contenu entier à la température optimale, et la répétition de ces étapes pour terminer le procédé.
