Definitions

  • the present invention relates to a method of producing fuel from tall-oil soap by treating the soap with carbon dioxide.
  • Tall-oil soap is a by-product of sulphate pulp manufacturing processes.
  • the soap can be separated out from black liquor when concentrating the liquor into heavy black liquor.
  • the tall-oil soap obtained has a pH of about 12 and is normally acidified with sulphuric acid to convert the soap to tall oil.
  • a process of this kind is, in principle, carried out in all sulphate pulp mills.
  • the tall oil obtained can be used as a crude product in the preparation of different chemicals or as fuel.
  • the present invention is based on the realization that tall- oil soap can be treated with carbon dioxide to obtain a fuel which contains tall oil that does not require the same degree of purity as tall oil intended for some other use.
  • the inventive process affords the important advantage of enabling tall-oil soap to be used as fuel without the addition of sulphur.
  • reaction with carbon dioxide is effected in one single method step, although it may be effected in two or more steps.
  • the soap is preferably diluted with liquid prior to being treated with carbon dioxide.
  • the soap is first mixed with an organic solvent. This enables a large part of the soap to be converted to tall oil.
  • the solvent used will conveniently have a high calorific value, because the end product will then have a higher fuel value.
  • the solvent used will preferably be combustible or fuel oil, such as diesel oil, for instance.
  • the process can also be carried out by mixing tall-oil soap with water prior to reacting the soap with carbon dioxide.
  • the amount of water used will preferably correspond to 0.5-3 times the amount of soap present, on a weight basis.
  • tall-oil soap is mixed with a water-immiscible organic solvent in the form of fuel oil or combustible oil.
  • a water-immiscible organic solvent in the form of fuel oil or combustible oil.
  • the manner in which the carbon dioxide is delivered to the soap will depend on the form in which the carbon dioxide is present, i.e. whether the carbon dioxide is in a solid state, a liquid state or a gaseous state.
  • the tall-oil soap was first mixed with diesel oil in essentially similar volumes. Upon completion of the reaction with carbon dioxide, a residual solution was separated from the reaction product whereupon the remainder was used as fuel. This fuel was found to have a good calori- fie value and comprised tall oil, diesel oil and tall-oil soap residues.
  • a solvent conveniently oil
  • the solvent can be replaced with water.
  • the tall-oil soap is suitably mixed with at least equal parts of water prior to being treated with carbon dioxide.
  • the tall-oil soap may also be mixed with a combination of solvent and water.
  • tall-oil soap produced in the manufacture of pulp can be used in an environmentally-friendly and cost- effective manner, by converting the soap into a high calorif ⁇ ic fuel without the use of sulphur. It is preferred from an economic and time aspect that this conversion is effected in one single step.
