Title: Methods for removing contaminants from algal oil

Abstract

Methods for removing contaminants from algal oil are provided. In an embodiment, a method comprises the steps of combining a sulfuric acid-aqueous solution that has a pH of about 1 or less with a contaminant-containing algal oil at treatment conditions effective to form an effluent. The effluent comprises a treated algal oil phase and contaminants in an acidic aqueous phase. The contaminants comprise metals, phosphorus, or combinations thereof. The acidic aqueous phase is removed from the effluent to form a contaminant-depleted algal oil.

  • A method is described for removing halogenated organic contaminants from solids contaminated therewith, said method including the steps of: comminuting the contaminated solids as necessary to produce a body of particles with a top size < 15 cm, at least some of which are contaminated; mixing with the particles in an amount sufficient to form a slurry of contaminant extraction agent consisting essentially of an alkali or alkali earth metal hydroxide, a liquid sulfoxide, and an alcohol; agitating the thus formed slurry of contaminant extraction agent and particles of solids for a period of time which is effective to separatemore » the contaminant from the contaminated particles; thereafter resolving the slurry formed by the mixing of the contaminant extraction agent into a fraction which is predominately liquid and fines and at least one, predominant particulate fraction; and separately handling the fractions into which the slurry is resolved.« less

  • Method and apparatus for removing oil and other organic constituents from particulate, inorganic-rich mineral solids. The method and apparatus are particularly suitable for removing oil from oil-contaminated drill cuttings. The solids to be treated are transferred into pressure vessel means wherein they are contacted with an extractant which is normally a gas but is under conditions of pressure and temperature to provide the extractant in a fluidic solvent state for the constituents to be removed, whereby the constituents are transferred to the extractant. The extractant containing the constituents is withdrawn from the pressure vessel and depressurized to render it amore » nonsolvent for the constituents and to form a two-phase system which can then be separated into extractant for repressurizing and recycling with proper handling of the constituents removed. In the case of removing oil from drill cuttings, the essentially oil-free cuttings can be disposed of in any suitable manner including dumping overboard from an offshore drilling rig.« less
  • This paper discusses an apparatus for separating gaseous contaminants and particular contaminants, including sticky components, from a dirty hot gaseous stream. It comprises a vessel defining an interior chamber; a walled housing disposed in the vessel for containing a moving bed of coarse particulate material therein, forming an enclosed area between the housing and the vessel; means for moving the bed through the housing; a dividing wall separating the enclosed area into a first section for flow of dirty hot gases therethrough and a second section for flow of cleaned gases therethrough; means for introducing the dirty gaseous stream intomore » the vessel and into the walled housing; means for discharging clean gases from the second section of the enclosed area; a supply of sorbent material disposed in the walled housing, after passage through at least a portion of the moving bed, sufficient to remove gaseous contaminants from the hot gaseous stream. The walled housing having at least one aperture in the walls thereof for flow of dirty gases from the walled housing into the first section of the enclosed area, with substantially no flow of the coarse particulate material therethrough; and hollow, ceramic, barrier filter units.« less
