SWING FOR PETROLEUM
AND PETRO CHEMICAL
STORAGE TANKS
SWING X5
Series, designed for use on storage tanks where there is
a need to draw off product from just below thesurface of
liquids stored in bulk.
Introduction
This unit safeguards the quality of roduct drawn off from the tank and substantially reduces settling times. Although the ATECO SWING Series Floating Suction Unit was riginally designed specifically for use in tanks storing aviation fuel where a water and sediment free product is essential, their application has gradually extended throughout other
industries.
Jet fuel quality is maintained by regular filtration and checks at all points and stages in its transfer to the airfield. The floating suction unit is but one of a large number of safeguards to ensure fuel quality and safety in air transport. Not only is water contaminated fuel a hazard to jet engine operation, but its presence also promotes the growth of bacteria and fungi which in turn can contaminate and block filters, and cause the fuel to be hazy and out of specification.
Sediment in finished fuel can suspend on the hydrocarbon/water interface and be sucked into the fuel upon transfer. By minimizing
water, sediment and bacteria, the ATECO SWING Series Floating Suction Unit can help provide a consistent high quality fuel and reduce the
time required for filtering, hydrotreating or increased settling time between shipments. It can also help jet, diesel and aviation fuel
meet color, filterability and haze specifications.The AKTEK ATECO SWING X5 Series Floating Suction Unit is ideal for use in crude storage applications where water is present.
Bacteria are becoming more prevalent in crude oil due to
down-hole water injection and water reuse practices in separation facilities. More water to the crude unit backs out crude from the
refinery. Increased sediment and bacteria can upset downstream equipment. These conditions may result in a loss in refinery
production. The floating suction unit can help provide a consistent high quality fuel by minimizing water, sediment and bacteria
which results in an increase in refinery production.
Features
There are six configurations available for vertical and horizontal tanks with fixed or floating roofs and outlets at the top, center or bottom, in sizes 3” to 24” [75 mm to 600 mm].
The fuel intake of the floating suction unit is positioned just below the free surface of the liquid level. The area available for drawing fuel
into the suction unit is arranged so that it faces substantially downwards, away from the free fuel surface to prevent a vortex from
forming which could cause air or vapor entrainment into the liquid stream.
At the heart of the Floating Suction Unit are the swivel joints which are triple-sealed units, specifically designed for floating suction
applications. Being fully sealed units, contaminated fuel can not enter the pipework via the swivel joint, and an internal reservoir allows the joint to be grease packed for life with an aviation approved grease. This eliminates the need for tanks to be drained
and taken out of service in order to grease the bearings.
Another benefit of these swivel joints is that they can only rotate in one plane and as such, the movements of the entire system are
predictable, unlike systems which use short lengths of flexible hose which can become twisted in several planes.
