Abstract

The present disclosure relates to a container adapted for holding liquid compounds liable to exothermic decomposition, said container provided with at least one explosion-safe liquid release system comprised of a conduit having an inlet and an outlet, wherein said inlet is located at the bottom of said container. Containers provided with such explosion-safe liquid release systems are particularly suitable for use with organic peroxides. Also disclosed are methods for storing or transporting liquid compounds liable to exothermic decomposition in containers of the present disclosure. Containers used in such methods may optionally hold inert particles and/or liquid diluents.

Claims

1. A container adapted for holding liquid compounds liable to exothermic decomposition, said container being provided with at least one explosion proof liquid release system comprising a conduit having an inlet and an outlet and a rupture disk positioned in said conduit, said liquid release system being operated by a pressure lower than the maximum pressure rating of said container, and said inlet of said conduit being positioned at the bottom of said container.

2. The container of claim 1 wherein said rupture disk is positioned at said outlet.

3. The container of claim 1 wherein said rupture disk is positioned in said conduit near said outlet.

4. The container of claim 1 wherein said rupture disk is the top of said container.

5. The container of claim 1 wherein said rupture disk is located near the top of said container.

6. The container of claim 1 wherein said container has a maximum pressure rating of about 6 bar.

7. The container of claim 1, wherein the cross-sectional area A of said conduit is about 0.005 m^-1 to about 0.05 m ^-1 of the container volume V where V is expressed in m³.

8. A method of storing or transporting a liquid liable to exothermic decomposition said method comprising use of a container holding both a liquid liable to exothermic decomposition and inert particles, said container having at least one explosion proof liquid release system comprising a conduit having an inlet and an outlet said inlet being positioned at the bottom of said container.

9. The method of claim 8 wherein said inert particles are selected from the group consisting of Raschig rings, Berl saddles, Pall rings and olefin particles.

10. The method of claim 8 wherein said liquid liable to exothermic decomposition is selected from the group consisting of organic peroxides, inorganic peroxides, azo compounds and mixtures thereof

11. The method of claim 8 wherein said container additionally holds at least one liquid diluent.
