摘要:
The invention relates to a fluid storage tank having an interior volume and a floor and having an internal spill containment chamber comprising a vent gas scrubbing apparatus or scrubber. The chamber may be defined by a containment wall which completely separates the chamber from the tank interior volume. The containment wall may comprise an exterior portion which extends beyond the tank wall. The scrubber is disposed within the chamber and comprises a gas inlet passing through the containment wall into the tank interior volume, a gas outlet for venting scrubbed gases, and a gas scrubbing chemical storage and circulation system.

It has been found that high porosity, high surface area protective materials such as expanded metal foil can be used in places such as the semi-confined, congested operating areas of chemical process plants to reduce or eliminate the hazard caused by the sudden accidental release and ignition of large quantities of potentially flammable vapors into the area.

The apparatus includes an insulated inner compartment member, an outer compartment member completely enclosing and spaced from the inner compartment member, with both of the members being liquid tight and with non-inflammable liquid being positioned in the space between the members and completely covering the inner compartment member, the inner compartment member being supported only at its upper end by the outer compartment member. Filling and discharge means connect to the inner compartment member from outside of the apparatus to complete the storage device.

The present invention is an apparatus with flexible membrane for oil storage and transportation, comprising outer wall, installation opening, blocking cover, oil inlet, oil outlet and breathing orifice. The membrane is arranged in outer wall and fixed in the installation opening or the fixing part of outer wall. The rest of membrane is separated from outer wall. Valve and quick coupling are arranged in both oil inlet and oil outlet.

A temporary hood for capturing vapors exiting from a material storage compartment of a vessel when the compartment is opened includes a base frame that extends around an opening to the compartment and is releasably secured to the vessel. An upper framework is releasably coupled to the base frame and extends upwardly from the vessel around the opening. A plurality of panels are releasably engageable with the upper framework and form an enclosure around the opening. At least one vapor discharge outlet fluidly communicates with the material storage compartment and a vacuum pump to allow the capture of vapors exiting from the opening when the cover is opened and the temporary hood is engaged with the vessel.
摘要:
A method and a device for reducing the evaporation of volatile organic compounds (VOC) when an essentially liquid petroleum product is being filled into a storage and/or transport tank (16) through a drop line (14), possibly also through a loading point (8), in which a gas or mixture of gases is supplied to the upper portion of the drop line (14) or the loading point (8) during the filling operation.
摘要:
A vapor pressure equalizer system for reducing the pressure of a storage tank that contains volatile liquid or fuel. A conduit is connected to the storage tank that draws vapors present in the ullage of the storage tank into the conduit. The vapors are circulated through the conduit to cool the vapor and return the vapor to the storage tank. In this manner, the pressure of the storage tank is reduced since the vapors being returned are cooler and smaller in volume than when the vapors entered the conduit. The conduit may be an open system that circulates vapors, or may be a closed system that circulates a cooling media through a radiator in the ullage of the storage tank. An electronic controller controls the operation of the system according to measurements that indicate an overpressure condition or a likelihood of future over-pressurization.

摘要:
A container is provided for collecting and filtering material. The container includes an inlet penetration through at least one surface of the container, and an outlet penetration through at least one surface of the container. The container further includes at least one filter being integral to the container such that the at least one filter is disposed of together with the container. The at least one filter is connected to the outlet. The material enters the container through the inlet, the material conveyed by a media (filtrate) is passed through the at least one filter resulting in a clean media stream (permeate), and the clean media exits the container through the outlet.
