Definitions

  • the present invention relates to a process and apparatus for the production of biofuel, particularly biodiesel.
  • the present invention attempts to overcome at least in part the aforementioned disadvantages of previous processes for the production of biodiesel.
  • a process for the production of biodiesel characterized in that it comprises the steps of combining oil or fat with an alcohol in the presence of a catalyst to form a reaction mixture, heating the reaction mixture to above 100 0 C and raising the pressure of the mixture to above 100 psi, passing the heated and pressurised reaction mixture along a fluid flow path in which turbulent flow is induced to promote a chemical esterification reaction to provide a reacted mixture of biodiesel and glycerine, reducing the pressure of the reacted mixture to about atmospheric pressure and the temperature of the reacted mixture to a temperature lower than the boiling point of the alcohol at atmospheric pressure and separating the biodiesel and glycerine into separate phases.
  • the apparatus comprises means for admixing oil or fat with an alcohol and a catalyst to produce a reaction mixture, means for increasing the temperature of the reaction mixture to above 100 0 C, means for increasing the pressure of the reaction mixture to above 100 psi, an elongated fluid flow path, means for feeding the heated and pressurised reaction mixture along the elongated fluid flow path, the fluid flow path being provided with means to induce turbulent flow in the reaction mixture so as to promote an esterification reaction to produce a reacted mixture of biodiesel and glycerine, and means for separating the reacted mixture into glycerine and biodiesel.
  • Figure 1 is a schematic representation of a flow diagram for operation of the process of the present invention
  • Figure 2 is a sectional elevation of a section of a tube used in a reactor of the flow diagram of Figure 1;
  • Figure 3 is a view similar to Figure 2 showing an alternative embodiment of the present invention.
  • Figure 4 is a front elevation of turbulator used in the tube of Figure 2.
  • FIG. 1 there is shown a flow diagram 10 of the process of the present invention.
  • the flow diagram 10 shows the primary inputs into the process being vegetable or animal oil or fat 12 and methanol 14, with an alkali metal methylate catalyst 16. It will be appreciated that other oils, alcohols or catalysts may be used within the process of the present invention.
  • the methanol 14 is first combined with the catalyst 16.
  • the resulting solution is then combined with the oil or fat 12 to form a reaction mixture with or without a separate mixing step.
  • the reaction mixture then passes through a heat exchanger 20.
  • the heat exchanger
  • the reactor 22 comprises a continuous small bore tube 24 which winds through an insulated housing 26.
  • the housing 26 is filled with absorbent and heat insulating material such as diatomaceous earth for heat insulation and fire protection.
  • the tube 24 may complete as many as 100 turns within the housing 26, thus resulting in an elongated flow path for the reaction mixture.
  • the tube 24 preferably has a bore in the range from 3/8" to 4"
  • the tube 24 contains means 25 to promote turbulent flow of reagents and products, in order to prevent flow stratification.
  • the means 25 are hereinafter referred to as turbulators 25.
  • esterification to biodiesel and glycerine in a two phase reacted mixture is substantially complete.
  • the two phases are at a very high temperature and pressure such as close to 150°C and 300psi.
  • the phases are first passed through the heat exchanger 20 to reduce the temperature to about 80°C. They may also be passed through an additional cooler, reducing temperature further to about 6O 0 C.
  • the pressure reducing means comprises an elongated, spiral flow path of relatively small cross-sectional size.
  • the biodiesel and glycerine phases travel along this flow path at a high speed. This means that the more dense phase, glycerine, is pushed to the outside of the flow path due to the operation of centrifugal forces. This enhanced separation of the phases during pressure reduction substantially prevents emulsification of the two phases.
  • a particularly preferred form of pressure reducing means is described in pending Australian Provisional Patent Application Number 200690611 in the name of the present applicants. The entire disclosure of Australian Provisional Patent Application Number 200690611 is incorporated herein by reference.
  • the biodiesel component is removed through an outlet 32 after passing through a dry wash apparatus 34.
  • the glycerine component is removed via an outlet 36.
  • the components • from the separation are passed through respective methanol flash apparatuses 38 (for biodiesel) and 40 (glycerine).
  • the methanol which is recovered is returned to the methanol supply 14.
  • the turbulators 25 are located at the joints between sections of tube used to construct the reactor 22.
  • the joints may be formed by means of butt welding, socket welding, flanging, swaging or any other means of connecting the tube sections.
  • Figure 2 of the accompanying drawings there is shown a portion of a tube 24 having an outer wall which is formed in multiple parts 52. Each part 52 has an end 54. Sandwiched between adjacent ends 54 is a turbulator 25.
  • the turbulator 25 has an outer circumferential flange 58 and a central aperture 60. Extending inwardly from the flange 58 into the aperture 60 are a plurality of radially extending projections 62.
  • the projections 62 extend inwardly a part of the way towards a centre of the aperture 60 as can be seen in Figure 4.
  • the projections 62 are disposed at an angle to the perpendicular relative to the length of the tube 24 so as to induce a spiralling effect in the flowing liquid.
  • the parts 52 are joined together by means of a circumferential bridging member 64 which has an inwardly directed projection 66 disposed between the ends 54. Further, the bridging member is attached to the parts 52 by means of welds 68.
  • the welds 68 attach the parts 52 to the bridging member 64 so that the parts 52 are each secured to the bridging member 64.
  • liquid reactants are fed into the tube 24 in the direction of an arrow 64 as shown in Figure 2.
  • the reactants pass through a plurality of turbulators 25 as they pass through the tube 24.
  • the presence of the projections 62 induces the flow of liquid to move towards a centre of the aperture 60 and away from the walls of the parts 52. This leads to increased turbulence in the flowing stream of reactants in the process of the present invention.
  • the bridging member 64 is secured in place between the parts 52 by means of circumferential compression members 70.
