Storage tanks are used in innumerable ways to store every conceivable liquid, gases and even solids in many 

different types of industries.

In oil refineries and petrochemical plants, they are playing a very important part of every days refinery 

operation and believe it or not, they even have an impact in the profitability of the refineries and

petrochemical plants. 

To non-technical people it may sound strange that storage tanks have impact on profitability of operation, 

but when we think that liquids do evaporate, than it became clear that if we prevent evaporation losses we

do make more profit. 

Especially in refinery operation where we have finished products like different grades of gasoline, kerosene, 

diesel, solvents and so on, if roofs are not properly designed and there are no vapour recovery systems in 

place, the losses due to evaporation of products can have huge impact on the profitability.

In a typical 156 foot diameter tank storing gasoline, our aluminum internal floating roofs which have a vapour

recovery of 96% or higher will save you 6241 bbls/year of products due to evaporation. 

In complex conversion types of refineries, we have several processes units like Atmospheric distillation unit,

Isomerization, reformer, FCC, hydrocracker, coker and so on, and they all produce gasoline blending

components and middle distillates. Every such unit has charge tanks, blending tanks or finished product tanks, 
so we can have tens of such tanks storing highly evaporative liquids. 

You can do your own mathematics and see what the cost savings can be on annual basis. 

And this is one of the very first advantages of our internal aluminum floating roofs: very short pay out time i.e. 

typically less than a year, but in most instances not longer than a year and half. After that, all that money stays

in your pockets.

IFR's have the advantage over vapour recovery systems (which don't recover more than 95 - 96% of vapours) 

because they are virtually maintenance free so your operating costs are basically nil,.

The aluminum roofs and dome covers are being used for various applications like covers for storage tanks in

refining and petrochemical industry, waste water treatment facilities, fire water tanks etc. 

Let me list couple of other advantages of our products: 

1) aluminum dome cover and internal floating cover cost about the same as
made from steel

2) external steel floating roof for 80,000m3 tanks with 74 m diameter (or 242 ft) weights about 540 tons -

that's almost 1,100,000 lbs. Our internal floating cover weight only about 17tons, and the dome about 110 tons 

3) virtually maintenance free - no corrosion

4) can be designed to withstand winds of hurricane level with speed above 250 km/hr

5) our internal roofs recuperate 96% and more of vapours

6) have at least 100% of buoyancy

7) no rim fires because of Faraday cage effect

8) much less erection time

9) it can be installed in existing tanks with standard man ways - no need to cut the tank wall

10) easy shipping to site with 40foot containers

11) easy assembling on site without any special tools

12) Very short pay out time - in a typical 156 foot diameter tank storing gasoline, it saves 6241 bbls/year

of products due to evaporation

We have over 14,000 installations world wide - more than double than our closest competitors, 

and our quality is above the requirements of API 650/653. In 40 years of our history, we never defaulted on a contract.
