Abstract

A method of producing aluminum chlorohydrate comprises adding small form aluminum metal pellets to a reactant receiving space of a reactor tank to form a pellet bed; adding aqueous hydrochloric acid to the reactant receiving space of the reactor tank; and continuously circulating the aqueous hydrochloric acid through the pellet bed. In some embodiments, the continuously circulating aqueous hydrochloric acid dispels reaction gases from the pellet bed. Methods described herein can, in some cases, further comprise consecutively adding additional small form aluminum metal pellets to the reactant receiving space of the reactor tank as the small form aluminum metal pellets are consumed in the pellet bed.

First claim

The invention claimed is:

1. A reactor system comprising:
a reactor tank having a reactant receiving space;
a bottom floor;
a hydration floor positioned in the reactant receiving space proximate to the bottom floor, the hydration floor comprising a plurality of fluid passing holes; and
a plurality of standpipes positioned on the hydration floor.

2. The reactor system of claim 1 , wherein the hydration floor comprises:
a reactant facing surface; and
an opposite reactor floor facing surface,
wherein the plurality of fluid passing holes extend through the hydration floor from the reactant facing surface and the reactor floor facing surface.

3. The reactor system of claim 1 , wherein the plurality of standpipes extend outward from the reactant facing surface of the hydration floor.

4. The reactor system of claim 1 , wherein the hydration floor is a hydration plate.

5. The reactor system of claim 1 , wherein the hydration floor is a modular hydration floor.

6. The reactor system of claim 1 , further comprising:
a manifold; and
a plurality of fluid dispersing pipes positioned proximate to the bottom floor and fluidly connected to the manifold.

7. The reactor system of claim 6 , further comprising a fluid supplying pipe fluidly connected to the manifold.

8. The reactor system of claim 6 , further comprising a hydration floor.

9. The reactor system of claim 8 , wherein the plurality of fluid dispersing pipes are positioned on a reactant facing surface side of the hydration floor.

10. The reactor system of claim 1 , further comprising a plurality of standpipes connected to the bottom floor of the reactor tank.

11. The reactor system of claim 10 , wherein each standpipe comprises a plurality of fluid dispersing holes positioned along a length of the standpipe.

12. The reactor system of claim 1 , further comprising a magnetic particle filtering system fluidly connected to the reactor tank.

13. The reactor system of claim 12 , further comprising a pellet filter, the pellet filter being fluidly connected to the reactor tank and the magnetic particle filtering system and being positioned therebetween.

14. The reactor system of claim 1 , further comprising a pump fluidly connected to the reactor tank.
