Description

S T O R A G E T A N K F O R L I Q U E F I E D F L A M M A B L E G A S E S Technical field of the present invention
The present invention relates to storage tanks for liquefied flammable gases, such as Liquefied Natural Gas (LNG).
Background of the present invention
In order to protect against the catastrophic release of flammable gas from a liquefied flammable gas storage tank, such as an LNG storage tank, safety regulations have been established. Current LNG safety standards provide safety classification of flat bottom LNG storage tanks as single, double and full containment.
This classification does not extend to bullet type LNG tanks. To make the safety designations of all types of tanks comparable, different storage tanks have now been classified according to their level of integrity:
A single level integrity is the lowest classification wherein catastrophic failure of the inner container will cause an uncontrolled spill of natural gas and release of vapour to the atmosphere. At the double level of integrity, failure of the inner container will not cause a liquid release, but such will result in uncontrolled release of natural gas vapour to the atmosphere.
The highest level is labelled as full integrity and provides for retention of any liquid spill and allows only controlled release of vapour to the atmosphere.
For example, various configurations of flat bottom tanks are shown in FIG. 1 to FIG. 5. FIG. 6 and FIG. 7 show configurations of bullet tanks.
FIG. 1 shows a double level of integrity flat bottom tank 10, having a concrete base 1 1 , an inner tank 12 of cryogenic steel, an outer tank 13 of non-cryogenic steel and an additional tank cup 14 of cryogenic steel. Also shown is an outlet pipe 15.
FIG. 2 shows another configuration of a double level of integrity flat bottom tank 20, having a concrete base 21 , and earthen bund 22, an inner tank 23 of cryogenic steel, an outer tank 24 of non- cryogenic steel and outlet pipe 25.
FIG. 3 shows a third configuration of a double level of integrity flat bottom tank 30, having a concrete base and liquid containment structure 31 , an inner tank 32 of cryogenic steel, an outer tank 33 of non- cryogenic steel and outlet pipe 34.
FIG. 4 shows a full level of integrity flat bottom tank 40, having a concrete base 41 , an inner tank 42 of cryogenic steel, an outer tank 43 of cryogenic steel and outlet pipe 44.
FIG. 5 shows a second configuration of a full level of integrity flat bottom tank 50, having an inner tank 52 of cryogenic steel, a non-self standing outer tank 53 of non-cryogenic steel supported on a concrete base and full containment structure 51and outlet pipe 54. FIG. 6 shows a single level of integrity bullet tank 60, as generally used for storage of air gases. The bullet tank 60 includes steel feet on concrete supports 61 , an inner tank 62 of cryogenic steel, an outer tank 63 of non-cryogenic steel and outlet pipe 64.
FIG. 7 shows a double level of integrity bullet tank 70, having steel feet on supports 71 , a concrete retention basin or bund 72, an inner tank 73 of cryogenic steel, an outer tank 74 of non-cryogenic steel and outlet pipe 75.
Currently there are no available configurations of bullet tanks that can be classified as full level of integrity tanks; i.e. that offer a safety level comparable to a full-containment flat bottom tank.
The full level of integrity is generally required for storage of liquefied flammable gas in populated areas. This is because single or double integrity tanks do not provide enough of a safeguard against the consequences of a failure of the inner storage container. In particular, those designs do not provide for containment of the vapour release that will occur rapidly in the event of a liquefied gas leak into the area surrounding the tank or the tank secondary containment.
In addition, catastrophic failure of the primary container may result in a large, cold gas cloud that represents a major hazard to the surrounding population because of a heightened risk of fire or explosion. While a full integrity storage tank may release vapour to the atmosphere through pressure release valves, such a release is carried out in a controlled manner and is significantly smaller in quantity.
For all of the above reasons, there remains a need in the art for improvements to storage tanks for cryogenic liquid gases.
Disclosure of the present invention: object, solution, advantages
Starting from the disadvantages and shortcomings as described above and taking the prior art as discussed into account, an object of the present invention is to improve storage tanks for cryogenic liquid gases. This object is accomplished by a storage tank comprising the features of claim 1. Advantageous embodiments and expedient improvements of the present invention are disclosed in the dependent claims.
The present invention provides new configurations of full integrity bullet storage tanks for cryogenic liquid gases. In particular, the present invention provides a full integrity bullet tank for storage of liquefied flammable gases, such as for storage of liquefied natural gases (LNG). The full integrity bullet tank of the present invention is achieved by having both the inner tank as well as the outer tank made of cryogenic steel. The full integrity bullet tank of the present invention comprises feet, in particular made of steel, on a support structure, in particular made of concrete, and an outlet pipe communicating with the interior of the inner tank. The advantages of the bullet tank of the present invention include the following:
Even if there is a leak from the inner tank, the outer tank will not fail from brittle fracture. In other words, by having the outer tank made of cryogenic steel, the design of the bullet tank of the present invention will survive even a catastrophic inner tank leak.
In addition, a burst disc can be provided in the outer tank to allow for controlled release of vapour to a safe location in the event of an inner tank leak. No containment pit, dike or bund is required.
In addition, by including an Emergency Shut Down (ESD) valve within the inner tank, it is possible to shut down the system in the event of an adjacent piping leak or rupture. This is different from conventional designs of storage tanks where the ESD valve is located externally to the tank.
Such a location for the ESD valve is not a safeguard against a total loss of tank inventory in the event of a pipe rupture or leak upstream of the ESD valve. As noted, by locating the ESD valve internally to the tank according to the present invention, the disadvantages of prior art tank designs are overcome.
Other advantages of the present invention are that the bullet tanks meet the requirements for classification as full integrity storage tanks, and therefore could be used instead of full containment flat bottom tanks currently used in the industry. For many storage capacities, particularly lower capacity storage, bullet tanks are easier, quicker and less costly to construct and install and therefore provide advantages with respect to capital expenditure and construction costs over flat bottom tanks.
In addition, the required footprint for the bullet tanks of the present invention is smaller than that of a flat bottom tank or a standard bullet tank within a dike. This is especially advantageous for LNG storage at fuel stations, for example servicing trucks, because the highest level of safety is achieved in the smallest possible area, often surrounded by high population density.
