Abstract
A self-contained storage system for hazardous materials includes a containment envelope enclosing a storage tank containing hazardous materials and forming a containment space between the storage tank and containment envelope. Leaked material is detected by one or more sensors in the containment space and, depending on the concentration or time rate of change in concentration of the leaked material, alarms and corresponding mitigation measures are reversibly activated to remove leaked material from the containment space.
Claims20
A system for storing a hazardous material comprising:
- a sealed storage tank containing the hazardous material,
- a containment envelope containing the storage tank and forming a containment space between the storage tank and the containment envelope,
- a sensor configured to detect the concentration of hazardous material in the containment space,
- a supply of mitigating fluid that sequesters or chemically neutralizes the hazardous material,
- a pump configured to deliver mitigating fluid to the containment space, and
- a controller in communication with the sensor and the pump
- wherein:
- the containment envelope comprises:
- a spray nozzle and a flush nozzle in fluid communication with the supply of mitigating fluid and a drain configured to allow mitigating fluid to exit the containment space and into a waste container or recirculation system and
- the controller is configured to deliver mitigating fluid to the spray nozzle when the sensor detects a first predetermined concentration of hazardous material in the containment space and to deliver mitigating fluid to the flush nozzle when the sensor detects a second predetermined concentration of hazardous material in the containment space.
A system for storing a hazardous material comprising:
- a sealed storage tank containing the hazardous material,
- a containment envelope containing the storage tank and forming a containment space between the storage tank and the containment envelope,
- a sensor configured to detect the concentration of hazardous material in the containment space,
- an alarm,
- a scrubber comprising a material capable of sequestering or chemically neutralizing the hazardous material and in fluid contact with the containment space,
- means for recirculating gas between the containment space and the scrubber, and
- a controller in communication with the sensor, the alarm, and the means for recirculating gas through the scrubber
- wherein:
- the controller is configured to activate an alarm and means for recirculating gas between the containment space and the scrubber when the sensor detects a first predetermined concentration of hazardous material in the containment space and to deactivate means for recirculating gas between the containment space and the scrubber when the sensor detects a second predetermined concentration of hazardous material in the containment space and
- the second predetermined concentration of hazardous material is less than or equal to the first predetermined concentration of hazardous material.
A method for storing tanks containing hazardous material comprising the steps of:
- enclosing the storage tank in a containment envelope, thereby creating a containment space between the storage tank and the containment envelope;
- measuring the concentration of hazardous material in the space;
- activating a means for removing hazardous material from the containment space when the concentration of hazardous material reaches a first predetermined concentration;
- and
- deactivating the means for removing hazardous material from the containment space when the concentration of hazardous material reaches a second predetermined concentration that is less than or equal to the first predetermined concentration.
