Abstract

Present disclosure relates to a novel process for purification of lipid material for further use as such as, for example, a source of fuel of chemicals.

First claim

The invention claimed is:

1. An apparatus comprising:
i) at least one mixing sector including at least 4 weirs, each of the weirs being tilted at an angle of between 5° and 20° relative to a horizontal plane, the at least one mixing sector being positioned at a top of the apparatus;
ii) at least one liquid distribution sector positioned between the at least one mixing sector and at least one liquid retention sector;
iii) the at least one liquid retention sector positioned at a bottom of the apparatus and having a plurality of subsectors in fluid connection with one another, each of the subsectors including a chamber and/or a vertical pipe;
wherein the at least one liquid distribution sector includes a first plate positioned at a lower part of the at least one liquid distribution sector and configured as a liquid distributor, a second plate positioned above the first plate that extends horizontally along the horizontal plane, and a third plate positioned between the first plate and the second plate, the third plate being tilted at an angle of between 5° and 20° relative to the horizontal plane; and
wherein the at least one liquid retention sector is in fluid connection with the at least one liquid distribution sector and is downstream of the at least one liquid distribution sector and is also positioned downstream of the at least one mixing sector; and
wherein the plurality of subsectors includes a first subsector, a second subsector and a third subsector, a vertical pipe connecting the second subsector to the third subsector.

2. The apparatus according to claim 1 , wherein the at least one mixing sector includes at least seven weirs.

3. The apparatus according to claim 2 , wherein the weirs are tilted at an angle of between 5° and 15° relative to the horizontal plane.

4. The apparatus according to claim 1 , wherein the at least one mixing sector also includes one or more collision plates positioned above the weirs.

5. The apparatus according to according to claim 1 , wherein the at least one mixing sector also includes at least one collision plate positioned above the weirs that is positioned to extend vertically in a direction that is perpendicular to the horizontal plane.

6. The apparatus according to claim 1 , wherein at least one mixing sector also includes at least one collision plate positioned above the weirs that is tilted at any angle of between 5° and 20° relative to the horizontal plane.

7. The apparatus according to claim 1 , wherein the at least one liquid distribution sector is in fluid connection with the at least one mixing sector and the at least one liquid retention sector.

8. The apparatus according to claim 1 , wherein at least one subsector of the plurality of subsectors is in fluid connection with the at least one mixing sector.

9. The apparatus according to claim 1 , wherein the first subsector is in fluid connection with the second subsector and/or the third subsector.

10. The apparatus according to claim 1 , wherein the third subsector is in fluid connection with the at least one mixing sector to recirculate material from the third subsector to the at least one mixing sector.

11. The apparatus according to claim 1 , wherein the at least one mixing sector has at least five weirs.

12. The apparatus according to claim 1 , wherein the at least one mixing sector has at least 20 weirs.

13. The apparatus according to claim 1 , wherein the weirs are tilted at an angle of between 5° and 15° relative to the horizontal plane.

14. The apparatus of claim 1 , wherein the weirs are plates or trays.

15. The apparatus of claim 1 , wherein the apparatus includes a body, the body having the at least one liquid retention sector, the at least one liquid distribution sector and the at least one mixing sector.

16. An apparatus comprising:
i) at least one mixing sector including at least 4 weirs, each of the weirs being tilted at an angle of between 5° and 20° relative to a horizontal plane, the at least one mixing sector being positioned at a top of the apparatus;
ii) at least one liquid distribution sector positioned between the at least one mixing sector and at least one liquid retention sector;
iii) the at least one liquid retention sector positioned at a bottom of the apparatus and having a plurality of subsectors in fluid connection with one another, each of the subsectors including a chamber and/or a vertical pipe;
wherein the at least one liquid distribution sector includes a first plate positioned at a lower part of the at least one liquid distribution sector and configured as a liquid distributor, a second plate positioned above the first plate that extends horizontally along the horizontal plane, and a third plate positioned between the first plate and the second plate, the third plate being tilted at an angle of between 5° and 20° relative to the horizontal plane; and
wherein the at least one liquid retention sector is in fluid connection with the at least one liquid distribution sector and is downstream of the at least one liquid distribution sector and is also positioned downstream of the at least one mixing sector;
wherein the plurality of subsectors includes a first subsector, a second subsector, and a third subsector; and
wherein a vertical pipe having at least one valve is positioned between the first subsector and the second subsector to fluidly connect the first subsector to the second subsector and a vertical pipe having at least one valve is positioned between the second subsector and the third subsector to fluidly connect the second subsector to the third subsector.

17. The apparatus according to claim 16 , wherein the at least one mixing sector is in fluid connection with the at least one liquid distribution sector and the at least one liquid retention sector.
