Abstract
Floating roof storage vessels including a vapor emission reduction system designed to be inserted into deck leg apertures, when the legs have been removed during hydrocarbon storage.
Claims16
An emission controlled floating roof storage tank apparatus comprising:
- a floating roof including:
- a plurality of leg sleeves distributed in the floating roof of the tank,
- a side or sides, and
- a bottom, and
- a vapor emission control system including:
- a plurality of vapor emission control apparatuses, each vapor emission control apparatus comprises:
- a top compression plate including an top plate aperture therethrough,
- a bottom compression plate including a bottom plate aperture therethrough,
- a compressible member interposed therebetween and including a compressible member aperture therethrough, and
- a compression assembly for compressing the compressible member,
- where each sleeve includes a vapor emission control apparatus inserted into a top of each sleeve and the compression assembly compresses the compressible member to produce a gas tight seal between the compressible member and an inner surface of each sleeve when the tank is in service and where the compression assembly decompresses the compressible member, when the vapor emission control apparatuses need to be removed from the sleeves and
- where the vapor emission control system reduces, substantially eliminates or completely eliminates volatile organic compound (VOC) emissions from the tank through the leg sleeves.

A method for reducing emission from a floating roof storage tank comprising:
- inserting a vapor emission control apparatus into a top of each leg sleeve of the floating roof storage tank, where the vapor emission control apparatuses comprise:
- a top compression plate including an top plate aperture therethrough,
- a bottom compression plate including a bottom plate aperture therethrough,
- a compressible member interposed therebetween and including a compressible member aperture therethrough, and
- a compression assembly for compressing the compressible member,
- compressing the compressible member via the compression assembly to produce a gas tight seal between the compressible member and an inner surface of each sleeve when the tank is in service,
- where the vapor emission control apparatuses reduce, substantially eliminate, or completely eliminate volatile organic compound (VOC) emissions from the tank through the leg sleeves.
