1. Coriolis Meters for Chemical Injection

2. Wellsite Chemical Injection
Why Treat
- Flow and production assurance
- Buildup of well by-products in the pipeline can reduce the flow of oil.
- Chemicals are used to prevent paraffin buildup, corrosion control, hydrate inhibition, limit asphaltene, and many other reasons
- Each well has unique chemical dosing requirements based on reservoir conditions
- Oil is treated after being pumped to the surface to prepare it to enter a pipeline in good condition
Result
- Chemical costs contribute up to 30% of the total cost to run a platform
- Companies must maintain reliable chemical injection programs

3. Offshore Chemical Injection
Multiple Wells
- One production platform will serve many subsea wells
- Multiple chemicals are delivered to each well and each needs flow measurement
-Pressures must be able to overcome the pressure of the oil coming to the surface and each well may be slightly different
- Umbilical's may be over a mile long and the chemicals must be delivered in the proper doses for the whole pipeline
- Treatment of produced water before returning it to an injection well is another application

4. Chemical Injection Hurdles
Chemical Makeup The chemicals used for treatment programs can consist of a single compound or a blend of different chemicals and are considered hazardous in most cases
Hazardous Locations An offshore platform is typically a Zone 0 or Zone 1 area (Class 1, division 1 or 2)
Varying Injection Rates Typical injection rates can range from 1 GPD (.15 LPH) to 1000 GPD (158 LPH), or up to 50 GPM (11K LPH) for methanol and other hydrate inhibitors
High Pressures Subsea injection pressures can be up to 20k psi. Top sides treatment pressures range from 500 psi to 5000 psi.
Technology knowledge Coriolis is a relatively little understood technology for chemical injection. Engineer education is vital going forward

5. The Rheonik Advantage
No moving parts Offshore operators are continuously looking to reduce maintenance issues. Currently PD meters are the measuring device of choice but the large oil companies are wishing to switch to Coriolis
High Accuracy Accurate dosing saves operators money in several ways: chemical cost, improved production, improved quality of the product
Variety of Materials Chemical composition can vary. The availability of meters in Super Duplex and Hastelloy is a great advantage
Pressure ratings Rheonik is close to being alone in the ability to reach standard chemical injection operating pressures

6. The Rheonik Advantage 1350 bar!
Multiple parameter outputs Using a Coriolis meter allows the user to monitor flow, density, and temperature with one instrument
Compact design Especially the small high pressure meters up to RHM08 have the shortest installation length and a very compact footprint. Best to integrate in skids with space restrictions
Variety of connection options GreyLoc ®, Autoclav, VCO, BSP, NPT, G, High-Pressure Flanges, ….
Handles pump pulsations and pressure spikes
Smallest flow rates – high flow range
1350 bar!
