Borets Vortex Gas Separator GSVB5-250
Borets Gas Handling Units Performance Capabilities Maximum intake free gas content , %* Vortex gas separator GSVB5-250 + Gas handler MNFB type 3
Vortex g as separator GSVB5-250
Gas handler MNFB type 3
Rotary gas separator + disperser
Tandem rotary gas separator
Rotary gas separator
* Tests were performed at Borets facilities in accordance with Borets procedures, at 2910 rpm
Borets offers two types of gas handling units, depending on the solids content in the formation liquid:
Standard – solids content is up to 0.5 g/l; Wear-resistant – solids content is up to 1g/l. 2
GSVB5-250 Properties and Characteristics
The operating principle is based on using the free vortex for the gas separation.
Vortex Gas Separator doesn’t have a separating rotor, what differs it from centrifugal gas separator.

GSVB5-250 Endurance tests at 3600 rpm Tests were performed at Gubkin Oil and Gas Russian State University. Vortex gas separator component part wear
Gas separator GSVB5-250 estimated run-life could reach up to 3500 days with solids content up to 200mg/l (in accordance with test results performed at Gubkin Oil and Gas Russian State University at 2910-4500 rpm).
GSVB5-250 Supply Dynamics and Field Trials
Totally 120 vortex gas separators were supplied to different oil companies. 5 units of GSVB5-250 gas separators are under field trials at Rosneft oil company. As of March, 2013 the MTBF totaled 312 days. Current MTBF is 436 days.
No failure caused by Borets equipment occurred during field trials
GSVB5-250 Failure Analysis Results
MTBF totaled 436 days at 402 mg/l solids content; Failure analysis results : – free shaft rotation; – no working parts, liner, base and head wear; – bearing sleeves minor wear.
Borets GSVB5-250 vortex gas separators trial results were recognized as success ful.
GSVB5-250 Vortex Gas Separator Benefits
Increased reliability due to the absence of separating rotor and correctly selected gas separator design type and materials reduce the flow hydraulic resistance and as a result – wear decrease.
Vortex gas separator wear-resistance is three times more than rotary gas separator.
Operates with formation fluid solids content up to 1g/l at 3500 rpm
Operates with formation fluid solids content up to 0.5g/l at 3500-4500 rpm
Separation quality of vortex gas separator is higher than rotary gas separator.
