Production separator package in onshore/offshore oil field

（1）Operating Principle and Characteristic

CEDEC can supply professional free water knock out package with horizontal and vertical vessel, which can separating the liquid into oil, gas and water three phase, the vessel dimension is determined by the process requirements. In order to separating the liquid into oil, water, and gad Phase(some times including sands), two phase separator, multi-phase separator or other special oil and gas treat equipment can be selected. The normal components are consist of following:

1.    Inter components

inlet diverter device

baffle plate

inlet cyclone separating pipe

mobile gas top

heater pipe

coalescer plate packs

foam remove equipment

fog catcher

vortex breaker

oil/water collecter

adjustable oil-water interface

sand-discharging system

2.     Vessel Design

low pressure and middle pressure design

interface/delaminate discharge

oil mud and/ or solid discharge

critical point sample

general internal structure

disassembled heat pipe

disassembled stainless coalesce equipment

stainless sand jetting/discharging system

manhole for maintanence

vessel material under special/atrocious conditions

Design according to ASME standard Volume 8（or equivalent standard）

Design according to GB150（or equivalent standard）

Up to NACE requirement under acid conditions

3.     product scope

liquid flow range from 150m3/d to 30000m3/d

inlet water content range from 0% to 98%

inlet of the equipment si special designed to remove foam, cushion/protect

（2）Option and type

The multi-phase separator supplied by CEDEC can be used in special work condition and special field, and it can make sure that the stream from all oil wells get suitable stream, it is propitious to next process treat. A special equipment is installed in the inlet of the three phase to lighten the movement of the tream, at the same time, break fluid plate, coalesce equipment, cyclones pipe are installed to reduce disturbance. The kinetic energy of the crude oil is absorbed in the inlet and the gas will be released out. In the water subside sect, the free water will be separated from the crude oil. The wallop of the inlet stream is detracted by the baffle, so the steady of next sect get better. The interface of the separator is controled by the oil/watere control instrument. Separate oil will discharge the equipment from the two or more isolation antrum, the water can discharge from the drain meatus, the gas discharge from the unattached meatus under the control of back-pressure valve.
