The better solutionNon-intrusive flow measurement with Most flows go in one direction only. However, this is not the case in a natural gas storage facility. Here, gas is either stored or removed depending on the market situation, an ideal application for clamp-on ultrasonic flow measurement with FLUXUS®. For more information: www.ugs.flexim.com j\_ Operators of gas storage facilities face specific measurement challenges: high pressure and flow rates during injection and even higher flow rates during withdrawal. The withdrawn gas is saturated with water-vapor and can carry free...

Field-proven clamp-on flow measurement _____ Underground gas storage ______ Underground storage of natural gas can take place in depleted reservoirs, in aquifers or in caverns previously leached out of subsurface salt formations. Although each storage type has its own characteristics, all underground gas storage operations face similar challenges: highly dynamic bidirectional gas flow under high pressure, wet with- drawn gas which must be dried before being fed back into the transportation network, prevention of hydrate formation, reduction or increase in gas pressures. FLEXIM’s FLUXUS®...

2 Injection of inhibitors The formation of hydrates can have a major impact on the plant's operability. In the worst case scenario, these solid crystalline structures, which resemble ice or wet snow, can clog the pipe thereby leading to process interruption and expensive maintenance work. In order to prevent their formation, hydrate inhibitors are injected into the wellbore. Piston pumps are usually used for injection, producing pulsating, highly dynamic flow under high pressure. FLUXUS® F is the ideal solution for monitoring the dose rate of the injected chemicals. Clamp-on ultrasonic...

measuring the gas flow and FLUXUS® F is used for measuring the quantity of removed water. The final stage of dehydration typically takes place in absorption towers, where the remaining humidity is captured by highly hygroscopic chemicals, e.g. glycols. FLUXUS® also offers the ideal solution for both liquid and gas flow measurement here. Glycol pumps can malfunction due to glycol corrosion or glycol lines can become clogged. FLUXUS® F reliably monitors glycol pump functionality and therefore helps prevent operational losses. The US Environmental Protection Agency (EPA) estimates that 17 BCF...

FLEXIM In-situ leaching for gas storage Underground gas storage in salt caverns starts out with the leaching of the cavern by solution mining. This process requires flow measurement of the injection water as well as the produced brine. FLEXIM's FLUXUS® F ultrasonic flowmeters have proven successful in solution mining applications due to their unparalleled versatility. FLEXIM's ultrasonic clamp-on technology allows for non-intrusive, highly accurate measurement of water and brine flow. By measuring the sound speed, the same instrument can be used to determine the density of the produced...
