Demulsifier arrangement - Custom chemical feed systems
Demulsifier Injection Packages POINTS OF APPLICATION FOR TYPICAL SAGD PROCESS Into emulsion ahead of FWKO (Free Water Knock Out) vessels and after Inlet Degasser Vessel. Into Emulsion as close to the well head as possible / ahead of the Inlet Degasser DESCRIPTION OF USE Demulsifiers are the key chemical to breaking or separating the oil in water emulsion coming from the well head. Recent application of demulsifier to each well head has proven benefits as it increases the reaction time with the emulsion. Reverse demulsifiers are also used to break the water in oil emulsion. DESIGN CRITERIA Typical Flow Range – 0.050 – 0.350 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 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.

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 Coriolis 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, bladder material shall be determined by the manufacturer. Pulsation Dampeners should have block and bleed configurations to allow for removal of the device for service if required. Spare diaphragm for the dampener should be provided for spare parts. On start-up bladder should be charged to 80% of system operating pressure to prevent damage from occurring to the device. 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 Coriolis type flow meters for the ranges or flows experienced. Special consideration must be given to the expected viscosity range of the fluid during selection of the measurement device. 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 (if required) can be properly tuned and to provide consistent pumping accuracy if the system pressure is less than 30 psig. Wetted materials for the PCV should be 316 SS, connections should be flanged for welded systems to allow for maintenance and removal. 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. 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. Wetted materials of the calibration column should be 316 SS with glass site. 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.
