Three Phase Separatoris a vessel designed to separate the gas that flashes from the liquid as well as separate the oil and water.3 Phase separatoris used when there is large amount of gas to be separaed from the liquid and the dimensions of the vessel are determined by the gas capacity.Three phase test separatoris used to mechanically separate hydrocarbon stream the liquid and gas components that exist at specific temperature and pressure.
Three phase separatordesign is important because separator is normally the intial processing vessel in any well testing and Early production facility. Improper design ofThree phase separatorcan be a bottleneck and reduce the capacity of the entire well testing orEarly production process facility.

Downstream equipment's ofThree phase separatorcannot handle high proportion of gas- liquid mixtures. Generallythree phase test separatororProduction separatorare designed to meet performance requirement of below 1% basic sediment and water content.

Gas and liquid separators are classified asThree phase separator, Two phase separator, Free knock out drums, Flare KO drum, Production separator, degassers, this can be either Horizontal or Vertical.

Increase in performance ofthree phase separatoris achieved by steady state equilibirium condition. Steady state conditions are achieved inthree phase separator, two phase separator, production separatorby proper control systems on the skid mounted packages.

In well testing industry, below standardthree phase test separatorsare commonly used.

Custom builtThree phase separatoralso available upon request

Three phase separatordesign is basically based upon fluid flow rate , temperature , pressure and fluid properties.

Test separatorsare designed considering 1 min retention time. Where as in early production or production facility the retention time will be based upon crude oil properties which is varying from 3 mins to 30 minutes.

VERPL(Vi Energ resources private limited )three phase separatorsare packaged in modular skids with pipings and control systems. Skid can be eitherCSC certifiedorDNV Certified.

Major Factors effectingThree phase separatordesign are Gas /liquid flowrates, operating & design consitions, surging or slugging tendency, physical properties, presence of impurities, foaming tendencies, corrosive tendencies, etc.

Three phase test separator consist of four sections Inlet diverter section, liquid collection section, Gravity settling section and Mist extractor section.

Our skid mountedThree phase test separatorpackages are assembled with liquid dump valve regulated by level controller to maintain steady state liquid level and steady state pressure of three phase separator is controlled by pressure controller with pressure control valve. Which directly impact in performance of the separator.

We choose proper internals based upon fluid properties and client requirements to optimizethree phase separatordesign.

Adual pot sand filteris a screen based process system, providing a cost effective and low maintanence solution for the separation and removal of solids.Dual pot sand filtersare pressure drop dependant, inlet and outlet pressure difference measures the sand accumulation and cleaning requirement notification.

Sand production in production line causes mechanical damage & erosion to chokes, flow lines, control valves, pumps and other downstream ancillaries. Further effect on reduced equipment capacity , failure of ancillaries, eratic readings of instruments and high environmental discharges.

Solids handling is an increasingly important task to reduce the project operational cost and an efficient process operations.

Production of sand and solids from oil and gas wells is a poison for drilling activities and processing facilities , Sand production is mainly due to failure of gravel packing and other sand control measure activities.

Dual Pot sand filtersare available in many sizes, typically 200 microns screen is widely used one.

Added advantages are no moving parts, low maintanence and avoiding downtime because of one working and one stand by, result in significant capital and operating cost savings

Dual pot sand filtersavoid shut in process of oil wells. Provides solids removal before oil contamination and removing sludge accumulation and other difficult problems.

If Series of oil well pipelines will be connected to single header is calledInlet manifoldheader.Inlet manifoldwill have two headers which is Production header and Test header.Inlet manifoldis the initial manifold header of upstream oil and gas processing system, MainlyEarly production facility and well testing oil and gas industriesare requires inlet manifold. Which is also calledwell head inlet manifold.

Production header of inlet manifoldis coming with safety shutdown valve for safe shutting down of well.

Test header ofinlet manifoldis a side stream from production line which will be used to test the oil and gas properties at regular intervals.

Test header ofinlet manifoldmay either connected withmultiphase meter or test separator of well testing.Vienerg manufacturing inlet manifoldscoming with production and test header in a compact skid modules for client flexibility.

Vienerg's Inlet manifold skidsare manufactured as skid to minimize field installation and labour cost. Some client prefersESD shut down system along with Inlet manifoldfor full operation ofsurface safety valve (ESD valve).

Two types of Inlet manifolds are now available in the oil and gas industry.

Conventional typeinlet manifold-from initial which is used , it requires bigger plot plan and number of manual intervention is required

MSM manifold - Multi selector manifoldwhich is coming with automatic switch over arrangement to divert production line to testing header and vice versa. Emerson is the leading MSM valve supplier in the oil and gas industry
