Blancon: a solutions oriented company

Blancon offers two approaches to hydrocarbon tank cleaning. These may be combined or

engaged separately depending on the specific tank conditions and client objectives.

Method A: Conditioning and fluidification of heavy sludge with waterbased, non-toxic, non surfactant Petromax formula: Heavy, solidsludges, including tank bottom cleaning, oil pits/ lagoons, sandy oil/slurry cleaning

Method B: Oil mixing and resuspension using P43 oil jet mixersfrom: Lighter sludges, sludges requiring re-suspension,general tank cleaning where sludges are not solid or the tankcontains a sufficient amount of good oil to be used in recirculationor new oil can be added to help the resuspension, as well as no veryhigh content of BS&Ws

Tank cleaning that necessitates only10 days of production down-timeAn example of tank de-sludging operation of a 70.000m3 floating roof flat bed tank with over 2.000 m3 sludge

Blancon offers a safe, fast and efficient method to remove unpumpable tank bottom sludges while

eliminating the high disposal costs by at clients request - recovering the previously unusableproduct for customers use

Complete mobility of our equipment allows us to respond to tank cleaning problems quickly in acost-effective way

Safety of plant, equipment and crews represent paramount priorities throughout our operations

All of our operators are trained to the highest standard to undertake any tank or vessel

cleaning operation

Equipment equipped to meet hazardous work area requirements

Non man entry

Blancon offers a complete desludging service available whenever the need may arise

to reduce your tank bottoms.

High volume sludge reduction without man-entry

Blancon uses a proven system/Rotary Jet

Mixers P43 - Veolia that works by directinga submerged jet of crude oil across thebottom of the storage tank

Dissolves and re-suspends theaccumulated sludge throughout theoverhead oil

Fluid dynamically powered

Valuable hydrocarbons are re-suspended intothe crude oil and not wasted (up to 90-95% oilrecovery)

The shell-mounted system is designed to be

placed at the tank wall

Normally using the existing tank shell manwayfor mounting

The solution is suitable for all roof types(floating roof application requires the legs ofthe roof to be out of the main operatingstream)

Note: Veolia Environmental Services UK plc isthe owner of P43 technology made in UK

Blancon offers solutions for very heavy build-ups where jetting may not be optimal

as well as oil and sludge treatment and separation services

Methodology overview: 10 days down-timeAn example of tank de-sludging operation of a 70.000m3 floating roof flat bed tank with over 2.000 m3 sludge

Stage 1: Client bottoms tank

The tank is bottomed to allow access through themanway covers for the jet mixers.

Degassing: This operation should be carried outbefore our specialist operators arrive on site.

Samples of sludge are taken to measure the

percentage in BS&Ws (Bottom Sediment&Water) and the sludge profile is carried out

Day 1 & 2 : Site preparation & installation

The site is prepared and the jet mixers areinstalled in the tank, mounted on custom-mademanway covers.

Then the high-volume pumps are connected,ready for the de-sludging operation

Methodology overview (continued)

Days 3 & 4: Re-filling the tank

After a thorough check of the installation, the clientrefills the tank to a pre-determined level with lightcrude.

The crude oil has to be sampled and BS&W levelsare measured

Days 5 & 6 : The cleaning process putting

the hydrocarbons back into suspension

The specialist team set the de-sludging operation inprogress by re-circulating the light crude andpumping it back into the tank at 700M per hour perunit.

As the jet mixer units rotate slowly inside the tank,the jet of crude will sweep up the sludge cutting, re-suspending and homogenizing it in the overhead oilready for normal refining processes.

Methodology overview (continued)

Day 7: Re-suspension completed

The crude should now be homogenized, withsoluble hydrocarbons in suspension and readyfor processing. At this stage the tank is drainedto a holding tank and the effectiveness of theoperation assessed. If there is still a largeamount of solids not suspended the operation isrepeated but for a shorter period.

Day 8 : Equipment removed tank now

available for re-use

After removal of the Jets/shell mounted de-sludging equipment, any small amounts of (ifany) remaining residues can be handled byconventional methods.

Alternatively, the tank can be put straight back

into operation for storing crude.

A typical test with 2600 m3 sludge showed that after a 15h-

operation, 2300 m3 are re-suspended, whereas after a 30h-

operation up to 2500 m3 were re-suspended.

Oil processing, dewatering and recovery

Continuous processing of extracted slope, or contaminatedsoil, and separating it into its base components for disposal,or re-use

2 stage and 3 stage, including centrifuging

Separation of oil, water and inorganics

Reuse of hydrocarbons

Reduced slope volume

Minimal waste generated

Environmental remediation applications for oil-contaminatedsoils etc.

Provides a cleaner and more liquid free cake in a 3 phase separation process*

Offers cleaner oil free tanks in preparation for inspection and repairs

* As tested by US Filter on their dewatering equipment, yielded asignificantly drier cake. Instead of the usual 30% - 40% liquidcontent on the filter test, the conditioned slope yielded a result of17.5%

** Results may vary

< 1% Water in Oil Content

< 0,2% of Sediments in Oil**
