Abstract

A hydrogen pipeline detonation arrestor is provided. The detonation arrestor includes a pipeline spool, having a segment length, an inner volume, an outer surface. The detonation arrester also includes a detonation barrier having a plurality of axially aligned quench pipes located within the inner volume. The detonation arrester is located within a hydrogen pipeline upstream or downstream of a hydrogen salt cavern storage facility.

First claim

1 . A hydrogen pipeline detonation arrestor comprising;
a pipeline spool, comprising a segment length, an inner volume, an outer surface, a detonation barrier comprising plurality of axially aligned quench pipes located within the inner volume,
wherein the detonation arrester is located within a hydrogen pipeline upstream or downstream of a salt cavern storage facility, and
wherein the plurality of quench pipes are axially alighted with the pipeline spool.

2 . The hydrogen pipeline detonation arrestor of claim 1 , wherein the pipeline spool further comprises a fluid cooling jacket.

3 . The hydrogen pipeline detonation arrestor of claim 1 , wherein the pipeline spool is submerged in a cooling fluid bath.

4 . The hydrogen pipeline detonation arrestor of claim 1 , wherein the pipeline spool further comprises enhanced heat transfer surface area on the outer surface.

5 . The hydrogen pipeline detonation arrester of claim 1 , wherein the pipeline spool is fixedly attached to a mechanical shock arrester.

6 . The hydrogen pipeline detonation arrester of claim 1 , wherein the salt cavern storage facility is used for storing hydrogen, methane, ethane, ethylene, or propylene.

7 . The hydrogen pipeline detonation arrester of claim 1 , wherein the salt cavern storage facility is used for storing hydrogen.

8 . A hydrogen pipeline detonation arrestor comprising;
a pipeline spool, comprising a segment length, an inner volume, an outer surface, a detonation barrier comprising plurality of quench pipes located within the inner volume,
wherein the plurality of quench pipes are axially alighted with the pipeline spool,
wherein the detonation arrester is located within a hydrogen pipeline upstream or downstream of a salt cavern storage facility,
wherein the plurality of quench pipes are aligned with the hydrogen pipeline, and
wherein the plurality of quench pipes are aligned with a flow of hydrogen gas.
