ACCURATELY MONITOR CHEMICAL INJECTION FLOW INTO HIGH-PRESSURE, HIGH-TEMPERATURE (HPHT) WELLS
Rheonik high-pressure Coriolis mass flow meters are perfect for chemical injection metering of deep water offshore and subsea operations. Offshore deep water HPHT oil wells can have operating conditions that are pushing 20,000 psi (1,378 bar) and 360°F (182°C). With well heads as much as 60 miles (100 km) from gathering points, high-pressure operation is essential to overcome high well pressures and friction losses within the pipelines.

RHEONIK HIGH-PRESSURE CORIOLIS FLOW METERS ARE PERFECT FOR DEEP WATER OIL AND GAS OPERATIONS.
Production Chemical Injection
Using Rheonik Coriolis deep sea flow meters in high pressure production chemical injection systems helps guarantee flow assurance requirements are met in pipeline and process equipment, optimizing processes in production operations. Chemical injection systems deliver flow assurance chemicals into production wells that prevent wax, asphaltene and scale buildup in order to maintain the production rate of oil from them. In addition to flow assurance, production injection systems also deliver chemicals used to protect and prolong the lifetime of pipelines and associated equipment by reducing and removing corrosive substances.
Rheonik flow meters are fitted injection systems to accurately measure the dosage rates of chemicals such as corrosion inhibitors, biocides, demulsifiers, drag reducing agents, and foam inhibitors.
Produced Water Treatment Chemical Injection
When extracted from the ground, hydrocarbons are accompanied by water and the ratio of water to hydrocarbons gradually increases over the life of the well. The implementation of modern secondary and tertiary recovery processes to increase production rates has also increased water content in recovered fluids. The recovered fluids are separated on site with the water being disposed of, often by reinjection back into the oil reservoir.
Chemical injection systems provide a convenient solution for adding chemicals like biocides, antifoam agents, deoilers, demulsifiers, nitrate inhibitors, and (sodium) hypochlorites to treat produced water prior to reinjection into a reservoir. Rheonik flow meters are used in those systems to accurately monitor chemical addition rates on the high-pressure side of the injection pumps, saving wear and tear on what can be expensive and critical components in the system.
Gas hydrates are crystalline structures that can form during natural gas extraction. Hydrates attach to the internal surfaces of pipelines and inline equipment, reducing (and eventually blocking) the effective cross-sectional area in flow lines and gas handling equipment. Typical chemicals used to control hydrate formation are methanol, MEG and LDHI / KHI. High-pressure Rheonik meters are available to measure hydrate inhibitors from drip feed rates to full flow rates in 2” lines.

Rheonik Coriolis meters can measure gas flows at very high pressures.
Rheonik Coriolis flow meters have exceptionally wide turndown, making them suitable for a wide range of compressed gas applications. With high pressure options up to 20,000 psi (1,378 bar), they can be utilized for reliable measurement for compressed gas delivery and filling with the advantages of having no moving parts to wear and no potential leak points except for the inlet and the outlet connections.

Many of the problems posed by high-pressure environments cannot be resolved with off-the-shelf solutions. We welcome the opportunity to work collaboratively to find the solution that's right for you.
HIGH-PRESSURE CORIOLIS FLOW METERS FOR GAS MEASUREMENT APPLICATIONS.
Hydrogen Dispensing for Fuel Cell Vehicles
Rheonik is a pioneer in the hydrogen fuel cell revolution. From the very outset, Rheonik has worked with all major hydrogen gas suppliers to produce accurate flow meters which handle the extremely high pressures associated with hydrogen dispensing. Hydrogen is transferred into fuel cell vehicles (cars, buses, fork trucks, trains, long distance trucks, construction equipment) very quickly, and at pressures up to 700 bar (and higher in the future). A flow meter measuring under these conditions must be both accurate and reliable enough to be usable for end user point-of-sale billing.
Billing Meters on Trucks Delivering Gases (i.e. hydrogen, LPG)
Very few filling stations are connected to pipeline infrastructure carrying gases such as hydrogen and LPG; for those who are not, it falls to trucks to deliver these gases into local storage at filling stations so it is available for dispensing into vehicles. In order to control and account for the quantity of gas being delivered to local sites, trucks are equipped with a flow meter that totalizes the amount of each gas transfer. The preferred method of transfer is mass metering (particularly for hydrogen), as this does not need additional calculations to account for pressure and temperature variation.
In order to transport greater quantities of gas, truck tanks are filled to high pressure. Rheonik Coriolis mass meters are fitted to trucks/truck trailers to provide records of all gas loaded or unloaded from their transportation tank(s). Rheonik meters are rugged and stand up to the rigors of road transport, while their compact size makes for convenient installation in on-board enclosures and housings alongside ticket printers, etc. Transmitters are operated directly from the truck’s 12VDC battery supply, removing the need for additional power supply converters or external sources and can be sealed against unauthorized change of configuration and settings, protecting the integrity of the measurement at all times.
CO2 Gas Injection
Carbon dioxide (CO2) is injected into oil reservoirs in order to increase output when extracting oil. It is an advanced oil recovery technique used in older oil reservoirs where the reservoir pressure is depleted. By injecting CO2 into a reservoir, the effective viscosity of any remaining hydrocarbon is reduced and it therefore moves more easily towards the production well where it is extracted. Another advantage of CO2 injection is that with regards to greenhouse gas emissions and global warming, CO2 injection provides a great vehicle for oil companies to offset CO2 emissions elsewhere within their operations.
CO2 is injected in relatively high volumes at pressures high enough that it becomes liquid, even supercritical. Rheonik Coriolis meters are ideal for monitoring the amount of injected CO2 (data critical to reservoir engineers) as they are rated for the high pressures and large quantities involved.
