Definitions
- the present invention relates to a vertical round container for storing liquids with a liquid cover covering the liquid surface, wherein the cover is sealed against the container wall by means of flexible sealing elements and on its underside at least one liquid-open chamber, in the gaseous media / vapors are included, wherein means are provided which determine the depth of immersion of the cover, and wherein supply / discharge lines are provided, with which the amount of the gaseous medium in the at least one chamber is variable.
- Floating covers of liquid surfaces have the task to prevent the exchange between the two fluid media, liquid and gaseous environment.
- Damper recovery is costly, energy intensive, and the overall emissions balance is negative compared to floating cover tanks.
- EP 0 059 298 A1 describes a floating roof for liquid containers, which consists of a slightly inclined to the center steel membrane, a peripheral side wall extending from the plane of the membrane both upwards and downwards, under the membrane by a plurality vertical partitioning steam cushion formed between membrane and liquid level, which carry the floating roof consists.
- the immersion depth of the floating roof is measured, and the floating position of the roof can be trimmed by adding compressed air into individual buoyancy chambers. Steam or gas surpluses under the roof are released into the atmosphere.
- this floating roof in the form of a ladle construction with steam pads and trim to maintain the horizontal swimming position is no pronounced Wasserammeizone ago. This means that the amounts of water on the roof can easily migrate, which requires frequent trimming with air admission under the membrane and subsequent steam delivery directly to the atmosphere. The entry of air or vapors with the filling of the container also requires the subsequent discharge of vapors into the atmosphere.
- the invention has the object of minimizing or eliminating possible emissions and operational risks at the storage container for volatile hydrocarbons in all operating conditions and at full emptying and initial filling.
- the disturbance of the safe floating position by precipitation, one-sided loads, entry of gaseous media in the storage fluid and leaks should be compensated and the need to commit the floating Cover should be omitted; All operating and monitoring tasks should be able to be performed from outside the container.
- An essential feature of the invention is that the supply / discharge lines for the gaseous medium are connected to a central unit which is provided outside the container. About this central unit, outside the container, it is possible to change the gaseous media in the at least one chamber so that thereby the conditions in the chamber can be adapted to the requirements.
- the gaseous media in the chamber may be sucked towards the central unit or may be supplied from the central unit to the chamber, thereby adjusting the pressure in the chamber and the level of the floating cover.
- the conduits routed through the fluid should be composed of rigid conduit sections, which in turn are connected by articulated spacers. With this articulated arrangement, the supply / discharge lines can adapt to the respective height level of the floating cover. In order to flexibly design the hinged intermediate pieces so that they can adapt to all movements of the floating cover, the articulated intermediate pieces, for example, formed from at least three hose joints.
- At least three should be distributed around the edge area of the floating cover towards the storage liquid open chambers are provided. These individual chambers then serve as trim chambers and are each connected via a separate supply / discharge with the central unit.
- the floating cover is trimmable at the three points distributed around the circumference, so that by supplying or discharging gaseous medium in the respective chambers, the floating position of the floating cover can be leveled.
- liquid side closed pontoon can be arranged to stabilize the floating position.
- This annular chamber is not divided into partitioned chambers, so that the same gas pressure prevails throughout the annulus.
- the amount of water collected in the tub can be regulated or deflated as necessary by level control. Appropriately, a certain minimum amount of water is left in the tub in summer operation to use the evaporative cooling for the storage liquid.
- the central unit as mentioned above should have at least one gas control unit with a manifold, a compressor and a manifold and valves such that each inlet / outlet can be connected to any other inlet / outlet via the compressor.
- gaseous medium which is discharged, for example, from a chamber to the central unit, can be fed via a corresponding switching of the valves and the compressor in another chamber to adjust the horizontal floating position of the floating cover , Discharge of polluting gases or vapors into the atmosphere is thereby avoided.
- the emissions that are possible at the edge regions of the floating cover or other emission regions can be supplied to the central unit by means of a slight vacuum by means of suction lines and a compressor of the central unit.
- the gases or vapors accumulating under the floating cover during first filling or emptying of the container can be sucked in via a compressor and fed to a gas utilization.
- the above-mentioned joint tube system for discharging the precipitates from the tub is usually constructed structurally stable, so that such a water drain line can be used simultaneously as a support element for the supply / discharge to the individual chambers and other emission sources by these supply / discharge lines along this water drainage line are performed.
- means may be provided to determine the immersion depth of the cover, preferably at extreme points, and depending on these measurements, the horizontal position of the cover via the displacement of the gaseous media in the respectively open at the bottom chambers regulate.
- trim chambers as indicated above, can be arranged below pontoon chambers, especially if existing floating covers are to be retrofitted with such trim chambers.
