• Fuel oil trends:

-Decreasing quality

-Same quality globally

• Reasons for lower FO quality than specified:

-Long transportation and storage times

• Risks with untreated Fuel oil:

-Ash content causing engine wear

-Water from deposits in tanks causing

corrosion

-Catfines, abrasive wear

-Corrosion from Sodium and Vanadium

Heavy Crude Oil Dehydration

Heavy oil production is increasing

Drivers

• High oil price justifies heavy crude oil development

and production

• Light oil discoveries are in minority

• Diminishing light oil production

Enablers

• Developments in horizontal drilling and production

• FPSOs and new riser technology (deep waters)

• Increase in refinery capacity and technology

• Developments in thermal production technologies

(e.g. SAGD)

Heavy Crude Oil Dehydration

Separation challenges

• Small density difference between oil and water

• Tight emulsions

• Solids (sand, clay, waxes, resins and asphaltenes)

• High viscosity

In traditional separation equipment

• High heating requirements and CO2 emissions

• High chemical consumption

• Long retention times – very big tanks

• Solids build up in equipment over time

• Difficult to reach product spec – considerable wash

water consumption to reduce salt content

www.alfalaval.com

Heavy Crude Oil Dehydration

The centrifugal solution

• Handles heavy and viscous oils with emulsions

• Lower separation temperature than traditional

separators means

– substantially reduced heating requirement

– substantial savings in fuel costs

– reduced CO2 emissions

– reduced chemical consumption

• Three-phase separation of oil/water/solids with

continuous solids discharge

• Optiphaser control system sustains high

performance with varying feed composition

Deck drains and Bilge water

• Alfa Laval is very active with process optimization

and research about new separation technologies

• An important reference list on Bilge water

• Alfa Laval has been working with the Deck Drains

treatment since the late 1980’s

• The EcoStream and Phoenix systems are helping

our customers to save money and build up an

environmental friendly profile

• Alfa Laval is also supplying process solutions to

treat oily water for shore based sites as well

Produced Water TreatmentOil & Gas Application

Why use produce water treatment

• Produced water trends:

- Increasing environmental issues/problems

- Tougher legislation

- Conventional equipment will have problem to

perform due to increasing HCO production

• Reasons for treating produced water with

centrifuges:

- To fulfill down hole water injection and overboard

water specification

- Oil production with high pressure drops will

increase the oil in water emulsion stability on the

water treatment side.

- Conventional equipment will need to be bulky

and long retention time needed.

- Energy, weight & space savings

Slop Oil TreatmentOil & Gas Application

Why use slop oil treatment?

• Slop oil trends:

-Increasing environmental issues/problems

-Tougher legislation

• Reasons for treating slop oil:

-Slop oil stored in tanks and ponds is an

environmental problem

-Reject streams are taking tank farm space

- Increased oil price globally

- Oil recovered can be sold at profit

- Waste can be minimized
