Definitions

  • the subject of the invention is method for treatment of loose and bulk substances, in particular sand and soil as well as huge areas contaminated with chain hydrocar ⁇ bons, in particular crude oil, crude oil derivatives, heavy oils and fats.
  • the aim of the invention is to desing a method for treatment of loose and bulk substances, in particular beaches, rocks and other huge area surfaces contaminated with polynuclear hydrocarbons due to ecological calamities resulting from failure of transportation means transporting these products, failure of pipelines etc.
  • the metod as per the invention consists in adsorbing hydrophobic hydrocarbons molecules by hydrophobic particles of adsorbent and next a solution consisting of water and activating agent is delivered into/on the contaminated substances.
  • the polymers used has a very developed adsorbing surface.
  • the ratio of water against activating agent amounts 0,5 - 10 g of activating agent per 1 cubic meter of water and generates a solution which under the pressure of 0,2 - 5 atm washes out or transports the polymer.
  • Efficiency of the method as per the invention is conditioned by the proportion of the sum of granulated polymer surface which should be 20 - 60 times bigger then the surface of treated loose, bulk or large surfaces substances.
  • Polymer is added to contaminated substances and next under the pressure of 0,2 - 5 atm a solution is supplied which causes that the mixture is separated into three layers, the first of which is formed by polymer with adsorbed hydrocarbons particles, thesecond layer makes water, whereas the third one is formed by a layer or surface of treated substances.
  • the adsorbent is formed of granulated polymer having granulation between 2 and 15 min.
  • Adsorbent and the adsorbed substance are separated by means ow known methods by sgueezing or centrifuging.
  • adsorbent In case of treatment of large area surfaces such as rocks, roads etc. spreading of adsorbent onto the contaminated surface is carried out by continuous supply of solu ⁇ tion under pressure. The adsorbent "sucks" hydrocarbons molecules and drop s off the reclaimed surface. Next, by means of water stream it is transported to eguipment where the adsorbent is physically separated from the adsorbet substance.
  • the metod as per the invention is effected in a closed system and facylitates achie ⁇ vement of huge effestiveness of treatment which guarantees its applicability in case of removal of the conseguences of ecological disasters caused by crude oil, oil and grea ⁇ se.

Abstract

Procédé pour le traitement de substances contaminées en vrac, notamment du sable et de la terre, et de vastes étendues contaminées par des hydrocarbures à chaîne, notamment du pétrole brut, des dérivés de pétrole brut, du pétrole lourd et des graisses. Ce procédé consiste à utiliser un adsorbant sous forme de polymère granulé de granulométrie comprise entre 2 et 15 mm, sa superficie totale étant égale à 20 à 40 fois celle des substances à traiter. Le véhicule de cet adsorbant est une solution d'agent activant et d'eau dans laquelle l'agent activant est présent à raison de 0,5 à 10 g par mètre cube d'eau.
