Abstract
A pressure relief module, such as a rupture disk module or a burst panel module, is disclosed. A pressure relief module may comprise a first membrane (10) configured to seal an opening of a contained system and configured to burst open when a pressure in the contained system reaches a predetermined burst pressure. A second membrane (20) may be joined to the first membrane to form a membrane interspace (30) with the first membrane. The membrane interspace (30) may be configured to prevent a backpressure in the contained system from changing the burst pressure required to burst open the first membrane (10). A pressure relief module may provide advantages for a low-pressure enclosure and/or to provide temperature stability and/or backpressure stability.
Claims21
A pressure relief module, comprising:
- a primary membrane;
- and
- a secondary membrane;
- wherein the primary membrane is configured to seal an opening of a contained system;
- wherein the primary membrane is configured to burst open when a pressure in the contained system reaches a predetermined burst pressure;
- wherein the secondary membrane is joined to the primary membrane to form a membrane interspace between the primary and secondary membrane;
- wherein the second membrane is exposed to a backpressure;
- and
- wherein the membrane interspace is configured to prevent the backpressure from changing the burst pressure required to burst open the primary membrane.
A pressure relief system, comprising:
- an inlet pipe having an opening;
- an outlet pipe having an opening;
- and
- a pressure relief module, the pressure relief module comprising:
- a primary membrane;
- and
- a barrier membrane;
- wherein the barrier membrane forms a fluid-tight seal with the primary membrane, and wherein the barrier membrane forms a membrane interspace between the primary membrane and the barrier membrane;
- wherein the pressure relief module forms a fluid tight seal between the opening of the inlet pipe and the opening of the outlet pipe;
- wherein the pressure relief module is configured to burst open in response to a set pressure within the inlet pipe;
- and
- wherein the barrier membrane is configured to prevent a change in backpressure up to a predetermined level within the outlet pipe from changing the set pressure of the pressure relief module.
A pressure relief system, comprising:
- an inlet pipe having an opening;
- an outlet pipe having an opening;
- and
- a pressure relief module, the pressure relief module comprising:
- a primary membrane;
- and
- a barrier membrane;
- wherein the barrier membrane forms a fluid-tight seal with the primary membrane, and wherein the barrier membrane forms a membrane interspace between the primary membrane and the barrier membrane;
- wherein the pressure relief module forms a fluid tight seal between the opening of the inlet pipe and the opening of the outlet pipe;
- wherein the pressure relief module is configured to burst open in response to a set pressure within the inlet pipe;
- wherein the barrier membrane is configured to maintain the set pressure of the pressure relief module throughout a predetermined range of operating temperatures.
A pressure relief system for a normally low-pressure enclosure, comprising:
- an enclosure containing a normally low-pressure process, the enclosure defining an outlet opening;
- a primary membrane sealing the outlet opening, the primary membrane further configured to open in response to a predetermined pressure within the enclosure;
- and
- a barrier membrane joined to the primary membrane and enclosure, wherein the barrier membrane covers the primary membrane, and wherein the barrier membrane is configured to open in response to the primary membrane opening.
