Cyclone unit (CySep)

 

The Cyclone separation plant (CySep) is a new technological solution.

 

Multistage hydrocyclone:

• To remove water from oil:
• Oil in water inlet: <30% (typ.);
• Oil in water at outlet: <40 mg / l.

 

Optimized cyclone geometry:

• Step 1: Removal of the base oil (BOW);
• Step 2: Pre-cleaning (PDx);
• Step 3: Cyclone removal of oil (DC).

 

First full-scale installation delivered in 2011 at Petrobras - for evaluation in 2012

Oil 979 kg / m3, water content> 75%

Substitution 1st separation stage: Continuous water flow.

6,400 m3 / day = 50 tons; 6m x 12m

 

Each stage performs a specific task to prepare the stream for the next stage of the cyclone:

• Primary oil removal cyclone;
• Separates most of the oil from the water;
• Integrated 2-stage cyclones;
• The pre-cleaning cyclone prepares the water before final cleaning in a traditional hydro cyclone.

 

Used for discharges of water / old deposits and offshore fields.

Heavy oil preparation technologies

 

Patented horizontal 3D dehydrators:

• Dehydration and desalting.

 

Patented Compact Electrostatic Coalescers (CEC):

• Dehydration and desalting;
• Coalescing.

 

Both solutions offer:

• Reduced cap. and operating costs, increased reliability, reduced risk;
• Reduced size and weight
• Reduced chemical supply (relative to competitors);
• Separation while reducing the demand for heat input;
• The ability to quickly break the emulsion.

 

Compact Electrostatic Coalescer (CEC)

Application area:

 1. Retrofitting / performance increase:

• High water inlet;
• No impact of vessel movement;
• Low maintenance costs.

2. Preparation of heavy oil:

• Emulsion breaking / reducing chemical consumption;
• Lower working temperature.

3. Finishing / Desalting:

• Compactness;
• Optimization of the required heat;
• Getting large drops, more than 4-10 times;
• Best separator efficiency after CEC;
• Water cut <0.3% from separator after CEC.

 

The intermediate layer preparation technologies

 

The intermediate layer (interlayer) is a stabilized water-oil emulsion or “interlayer” that forms at the water-oil contact and acts as a barrier preventing the separation of water from oil and oil from water.

 

The field is a mixture of heavy oil, water and mechanical impurities, whose density coincides with the density of the mixture of oil and water and is therefore difficult to determine. Obtained during the effects on the reservoir, the site also contains asphaltenes, which can cover level gauges with an impermeable layer.

 

The field tends to grow exponentially, resulting in poor quality oil (flow with oil) or withdrawal from the water treatment unit (flow with water).

 

Oil companies may hire third-party organizations to dispose of the industrial layer from their facilities (increased costs) or may involve third-party organizations using mobile centrifuge installations (increased costs), or may consider our solutions.

 

Our company offers two solutions:

• RagBuster - removal of interlayer for processing in the CEC;
• Slop-Oil Triter - preparation of the interlayer at the patented Installation preparation (standard or individual design).

 

Slop-Oil Triter is a simple technological process in which the oil layer is heated to 150 ° C under a pressure of 5 atm. in a section similar to the standard Heather-Trieter. Then heated industrial evaporation operating under low pressure, where water passes into steam along with the light layer is supplied to the section with oil fractions and evaporates from the oil. The vapors are then condensed and the condensate and water are separated in a separate container.
