Definitions
- the present invention relates to a storage facility for storage of volatile hydrocarbons with at least one vertical round container according to the preamble of claim 1.
- a first problem area are steam leaks in special operating situations, the extreme heating of the contents of the storage tanks on summer days, the Inadvertent discharge of air or vapors with tank filling (eg during ship unloading or from the pipeline), the introduction of warmed storage products and the release of stored products.
- a second problem area is that the container volume can not be fully utilized because the floating cover loses its emission-limiting effect as soon as the liquid level in the container drops below the support height of the floating cover supporting the floating cover at the bottom of the container.
- a safety valve opens to protect against vacuum and to prevent possible destruction of the floating cover.
- air from the atmosphere replaces the removed storage liquid and, in the event of subsequent filling of the container, forcibly leads to vapor emissions which amount to up to one kilogram of stored product per cubic meter of air. Therefore, the loss of storage volume is about 10% to 15%.
- Floating roof supports are provided, with which the floating roof is supported at low liquid level at the tank bottom.
- the roof supports are moved to a higher position so that they protrude only about 1 m from the bottom of the floating cover;
- the distance between tank bottom and deepest floating roof position is only about 1 m and the tank volume is better usable.
- the roof supports are displaced so that they fill the container
- a further, fourth problem area is to be seen in that after a full emptying of the container for a designated repair, the gas space must be degassed under the floating cover. For this purpose, external companies are needed, which suck and burn the vapors from the dead space of the container. This work can take several weeks for larger containers and leads to enormous cost and security risks. In addition, during the last combustion phase of this work, as the concentration of vapors decreases, a foreign gas must be mixed prior to incineration, a measure required for environmental reasons.
- Another fifth problem area is the fact that the enormous expense of emptying the container not only leads to enormous costs and risks, but also represents a major impediment to a flexible re-allocation of the tank space for a possible product change. This is in contrast to today's demand that tank farms must be very flexible to changing storage needs designed to rent the existing storage volumes well.
- the present invention is based on a storage for storage of volatile hydrocarbons with at least one vertical round container, wherein the round container is provided with a liquid surface covering, floating cover in the form of a floating roof or a floating cover; the annular space formed between the cover and the container wall is sealed by means of flexible sealing elements.
- the floating cover fittings are integrated for the automatic control of the pressure and the negative pressure in the space below the cover.
- the present invention is based on the object, the above-mentioned emissions and fire risks drastically to reduce. Furthermore, the storage space is to be made almost 100% usable and the flexibility of the storage space for product re-allocations can be increased. It should also be possible to make emissions usable for energy purposes.
- the invention is characterized in that the fittings of the at least one round container are connected to a Dämperneitung, which is guided at the upper edge of the container (preferably over the upper edge of the container) and in turn connected to a separate vaporizer reservoir, the Buffers of vapors which under certain operating conditions must be supplied or removed from the space under the cover.
- the round tank and the vapor expansion tank form a closed system, whereby a complete separation between atmosphere and storage product takes place.
- the fittings are designed to protect the space below the floating cover against overpressure as well as against a potential vacuum.
- the Dämperneitung within the round container has a vertically extending portion which is formed as a bellows and which expands or contracts depending on the floating height of the floating cover. Because of this bellows, the ducting is extended or shortened according to the position of the floating cover as a result of container filling.
- the bellows of the ducting surround a fixed support and that the bellows be secured to the upper end of the support.
- the attachment point of the bellows to the carrier forms a fixed reference point for the bellows.
- the lower end of the bellows is preferably attached to a structural part of the floating roof and changes with the floating position of the floating roof.
- the Dämimineitung can be performed within a round container along a roll ladder.
- a roller ladder is pivotally connected to the region of the upper edge of the round container while the lower end is provided with rollers and rolls along a runway resting on the floating cover. With changing floating height of the floating roof, the roller ladder changes its inclination, the rollers are always guided along the runway.
- the Rolleiter represents a stable support for the dairy line.
- the vaporizer reservoir is preferably one having a flexible diaphragm on which a ballast weight acts. About the size of the ballast weight used, the necessary pressure in the space of the expansion tank can be adjusted.
- annular space between the floating cover, the container wall and an edge seal above the liquid surface should be connected to the space below the floating cover to dissipate also from this annulus accumulating there vapors.
- the invention is preferably to be used when the deposit comprises several storage containers.
- these storage containers are connected to a common vaporizer reservoir.
- the vaporizer surge tank with its ballast weight, taking into account the flow resistances of the ducting, should be designed to avoid negative pressure in the space below the cover by supplying vapors into this space, and should also be designed to have a given gauge pressure in this space below the cover by absorbing vapors from the room.
- a fan can be arranged in the dimming line, which is controlled by pressure sensors in the tank container below the floating cover.
- the invention also relates to a storage facility with a plurality of storage containers, wherein these storage containers are subdivided into at least two groups, wherein the assignment to the at least two groups takes place after their pressure exerted on the liquid via the floating cover.
- Each storage container in a group is associated with a vaporizer reservoir adapted to this pressure.
- the different vaporizer reservoirs are connected via a vapor equalization line into which a booster blower for delivering vapors from the low pressure vaporizer reservoir to the higher pressure vaporizer reservoir is inserted.
- the remaining in the lowest position of the floating cover of the round container between the floating cover and the container bottom space is connected to a Spül thoroughlykeitsvorrat and existing in the remaining space after emptying of the container hydrocarbon vapors by introducing the rinsing liquid into the round container to Support height of the floating cover to the vaporizer reservoir to be dissipated.
