Reverse Demulsifier Injection Packages
POINTS OF APPLICATION FOR TYPICAL SAGD PROCESS
Ahead of FWKO (Free Water Knock Out) Vessel
DESCRIPTION OF USE
Reverse-Demulsifiers are used to separate the water from the oil water mixtures (water droplets
in oil is a reverse emulsion) a more difficult process than demulsifiers. This process is enhanced
through the addition of clarifiers or polymers as well.
DESIGN CRITERIA
„„ Typical Flow Range – 0.020 – 0.150 m3 / hour in typical applications.
„„ Typical Pressure Range – 17 bar / 250 psig maximum design pressure.
Recommended Pumping Device
The ProMinent Orlita DR series metering pump provides the ideal solution for these
applications because of flow range ability of the pumps and the thick and clotty consistency
of the chemicals. The DR is a valveless rotating piston pump and can handle thick fluids. Not
having any check valves the pump can run over a significant turn down ratio, often in excess of
100:1 turn down.
Materials of the pump head should be 316 SS, connections should be flanged to allow for the
easy removal of the pump from the system for cleaning / repair.
Pumps should be mounted as closely as possible to the tank (with 5 feet) and should be run
with flooded suction at all times to promote the flow of the reverse demulsifier to the pump
head and to prevent system starvation.
Pump speed should not exceed 80 strokes per minute as this will help handle wide viscosity
ranges.
Piping Materials / Compatibility
All materials in contact with the fluid are typically 316 SS materials selection of seals should
be Teflon as this allows for the potential to change chemicals in the future if needed and
provides a more universal compatibility to the service.
Connections / package construction can be of tubing or welded pipe. Line sizes are generally
¾” to 1” in diameter for these flow ranges. Suction lines should be upsized one diameter over
the pump inlet to account for viscosities. Occasionally these chemicals can set up if left in
stagnant lines for too long. If this is the case the either a preventative maintenance program
to drain the stagnant services should be implemented, or the function of the pumping system
should be set to regularly change the duty pump to prevent stagnation of the chemical in the
suction or discharge lines.
All components on the system shall have CRN registration and MTR reports.
Package registration to ABSA is not required as the fluid is non-expansive, however final design
should be reviewed and stamped by registered engineer in accordance with ASME 31.3 to
confirm proper selection of materials.
All welding and fabrication shall be completed in an approved ASME 31.3 shop with qualified
personnel.
Drain and flush connections should be provided so that chemical can be drained and cleaned for
service of main system components.
All instruments should be equipped with block and bleed valves so that they can be removed for
service.
Consideration to temperature should also be made as with these chemicals viscosity will increase
as the temperature decreases. If this is the case the pump system should be designed to handle the
highest expect viscosity.

Additional System Requirement
Safety Relief Valve Selection – Safety relief valves should be sized for blocked flow / blocked
discharge conditions. Relief setting should be 15-20 % of maximum pump pressure. Wetted components
of the valve shall be 316 SS, with CS non-wetted parts. Valve connections should be flanged to allow for
easy removal of the valve for testing, and reconfiguration. Discharge from the relief valve should be run
back to the pump suction, or directly back to the tank. All relief lines should be sloped to that chemical
does not stagnate in these branches.
Pulsation Dampener – if discharge lines from the pumping system to the injection point are longer
than 20 meters a pulsation dampener should be used to smooth out pulsation impulses on the discharge
lines and to inhibit leaks on fittings and piping fatigue. Pulsation dampeners should also be used if a flow
measurement device such as a Coriollis Meter is being used on the pump package to confirm and adjust
flow rate of the pump itself as these meters require a smooth flow. Wetted components on the dampeners
shall be 316 SS with Teflon diaphragm, again to accommodate the future potential of changing chemistry
and provide flexibility of the overall design.
Flow Measurement – there are a number of technologies used to measure the flow output of the
metering system reliably. Selection of a proper flow measurement device should be done with the
equipment manufacturer to account for accuracy over the full range of service. Typical technologies are
gear or piston type mechanical meters, or Coriollis type flow meters for the ranges or flows experienced.
Special consideration must be given to the expected viscosity range of the fluid during selection.
Pressure Control Valve – Pressure control devices are used downstream of the pump if the injection
pressure is expected to vary. A PCV determines the operating pressure of the system and maintains
a consistent back pressure so that the system pulsation dampener can be properly tuned. If the
downstream pressure is not expected to fluctuate then a PCV is not required for this package.
Calibration Column – A vented graduated calibration column shall be provided on the suction side of
the pumping package to allow for manual calibration of the system. In order to work accurately isolation
from the tank should be provided. This way only chemical from the calibration column will feed to the
pump. The column should be installed so that it can gravity fill from the storage tank, thus the high level
of the column should be within the tank level. The calibration column is not a pressurized vessel and
as a result does not require a CRN. The calibration column should be sized for at least 30 seconds of
pump design flow and graduated to show total volume pumped in a given time period. During operation
calibration columns should always be completely drained of chemical to prevent the material from setting
up or forming clots that can plug the suction lines of the system and cause pump starvation.
Pressure Gauge – Pressure gauge with 316 SS isolator should be provided on the discharge side of the
Technical changes reserved.
skid, isolation with double block and bleed should also be provided to allow for proper gauge maintenance
and testing as required.
