4 Oil waste In the course of process, oil and gas industry inevitably generate oil wastes Oil wastes volume (indicative) about 1 % of the oil production Process Drilling Stimulation Oil treatment Transport Refinery Waste type Drilling cutting, muds and fluids Fluids after well interventions Oil sludge & stable emulsion Oil contaminated soil & slop oil Oil sludge & stable emulsion Volume, mln. m3/year Oil content, % Oil volume, mln. m3/year 2,0 5 0,10 0,3 50 0,16 0,4 50 0,20 4,5 0,3 20 0,06 TOTAL 5.02 Centrifuge technologies 4

5 Oilfield sludge processing In oilfield operations oily sludges are produced as sediments in tanks and apparatusand from oil spills (e.g. in the course of maintenance / repair work, or due to pipeline leaks). collected in lagoonsand withdrawn from there for processing Description: Sludges have extremely high solids contents at moderate to high oil contents. A water content in the order of 40-80% by volume, approximately 10-50% by volume oil phase with rather high viscosity a high solids content (in the order of 10-40% by volume) with potentially very large particle sizes potential content of significant amountsof other debris Oil field sludges require special attention be given to the mechanical pretreatment of the sludges prior to processing Centrifuge technologies 5

6 Emulsion processing During crude oil production, there are several sources of mixing including: a water-in-oil emulsion an oil-in-water emulsion Flow through reservoir rock Bottomhole perforations/pump Flow through tubing, flow lines and production headers Valves, fittings, and chokes Surface equipment Gas bubbles released because of phase change The greater the mixing, the smaller the droplets of water dispersed in the oil and the tighter the emulsion. a water-in-oil-inwater emulsion Emulsion studies have shown that the water droplets can vary in size from less than 1 μm to more than 1000 μm.

8 Slop oil in refineries In refineries all kinds of waste oils are produced, socalled slop oils. They come from drainages, residues and cleaning processes, especially cleaning oil tank bottoms. Most of these slop oils contain a high percentage of oil which can be mixed with crude oil to be processed in the refinery. If this slop oil is treated, not only disposal costs can be reduced, but profit can also be generated with the oil phase recovered from the slop. Centrifuge technologies 8

10 Targeted Technology Target: Mobile and universal equipment for oil sludge and emulsion treatment Location 1: Oilfield Location 2: Close to potential area of accidents (pipelines, refineries, sea ports) Time of operations: During oilfield exploration (15-20 years) Feeds: Sludge starting from the very beginning of the oilfield exploration Emulsion starting from the time when production liquid contains the water Centrifuge technologies 10

11 Available Technologies Current technologies: Incineration Biological cleaning Neutralization by chemicals Pirolisys Separation Other Utilization costs: > 1 bln. USD per year Oil yields: < 50 %, since most of the technologies lead to irretrievable oillosses Most effective technology: oil wastes separation by horizontal scroll centrifuges (tricanters or decanters) Limitations of existing technology: poor quality of separation, resistant to separation feed (emulsion) or feed with low solids content can t be processed high initial cost high operatingand maintenance costs low capacity tendency to foul Centrifuge technologies 11
