Electric actuators
guard against accidental oil spillages
Category: Pumps, Valves and Fittings
Reference: 37108
Rotork's CVA electric control valve actuator is providing a critical failsafe function on packaged oil-water separator (dewatering) units supplied to a refinery in Antwerp. Manufactured by Facet, the dewatering units utilise a passive gravity-flow technique for separating oil and solids from waste water in storage tanks. Specially designed coalescing plates manipulate the flow of water, forcing the oil to the top and enabling the solids to sink to the bottom, whilst the cleaned water passes through. The filtered water is clean enough to be released into the environment. The CVA actuators have been installed to guard against accidental oil spillages or contamination that could occur if the power or the control signal to the unit is interrupted. The explosionproof certified CVA actuators will immediately close valves on the water outlet and oil return lines if the power or signal is lost. The compact actuator design uses integral super-capacitors to enable failsafe operation, eliminating the inconvenience, cost and additional space considerations associated with separate battery packs or alternative back-up power sources, particularly in the hazardous environment of a refinery. In addition, programming the failsafe operation is a standard part of the CVA's non-intrusive commissioning routine, simplifying instrumentation requirements. Space was an important consideration in the overall design, since each dewatering unit is packaged in a compact weatherproof housing with an external manifold for on-site pipework connections. The manufacturer promoted the adoption of a linear valve design for the application as an alternative to the rotary ball valve originally specified. With a stroke of only 7mm, the linear valve fully closes in only 1.5 seconds, instead of the 15 second closing time for the ball valve, providing increased failsafe response and security. In addition to the convenience and speed of non-intrusive commissioning, the CVA also features built-in data logging, providing diagnostics to reduce the risk of unplanned process interruption. The actuators for this contract have been supplied by Rotork Holland for a total of eleven dewatering units.
Water monitoring solution
for exporter of metallurgical coal
Category: Measurement and Instrumentation
Reference: 37324
One of Australia's largest exporters of seaborne metallurgical coal operates coal mines in Central Queensland supplied by fresh water extracted from borefields, rivers and dams. It owns and operates hundreds of kilometers of pipelines, through which it moves tens of thousands of megalitres of fresh water per year to its own and competitors' operations and to local mining communities. For monitoring raw water in the network, Krohne Australia supplied 26 Waterflux 3070 C battery operated stand-alone water meters.
Access to a reliable source of water is an essential requirement for coal mines. Even those mines that do not wash their product through a preparation plant need significant quantities for dust management, drilling, human consumption and numerous other uses. The monitoring of water use to support mining operations in remote areas represents a significant challenge to all mineral companies operating in Australia as often the infrastructure and management systems provided by the company are also used to supply local communities and rural industries. Measurement and balancing of water flows can allow investigation and analysis into water management and substitutions. .An essential pre-requisite to gaining better understanding of water consumption is a more comprehensive water flow monitoring network.
As mechanical water meters require a high level of maintenance and have inaccuracies e.g. when measuring large variations in flow rates, the company chose Waterflux 3070 C, a battery powered, maintenance-free electromagnetic water meter, to provide a reliable solution for the mine site's, and communities' remote water monitoring needs. The Waterflux 3070 has a unique flow sensor design with rectangular cross-section allowing for a significant reduction of magnetic field excitation. The coils are arranged so that a strong, homogeneous magnetic field is formed. The measurement is therefore independent of the flow profile and measurements are very stable. This results in a very good low flow performance and allows the operation without inlet and outlet runs. Further, the Rilsan liner of the flow sensor is highly resistant to pressure or vacuum conditions, to corrosion and aging. An optional data logger and GSM module allows for remote meter reading and wireless transmission of measurement data and status information.
Natural gas regulator
ensures gas delivery for high pressure transmission and distribution applications
Category: Pumps, Valves and Fittings
Reference: 37386
The design of the DN 100 Fisher EZHSO Series spring-to-open pressure reducing regulator incorporates a unique spring cartridge that offers a fail-to-open alternative, ensuring gas delivery in the event of diaphragm failure or lack of supply pressure to the pilot. The failure action is the opposite of the EZH Series spring-to-close pressure reducing regulators. The Types EZHSO and EZHSO-OSX (slam-shut) regulators are available in DN 25, 50, 80 and 100 sizes. These new offerings provide the same benefits as Emersonâs proven Fisher Type EZH regulators; such as true no-bleed design, top-entry maintenance, bubble-tight shutoff, and inlet/outlet rating of 103 bar. The Whisper Trim Cage option is available for DN 50, 80 and 100 sizes, opening a broader application range for this product family. Noise reduction of 10-20 dB(A) can be achieved, depending on the application.
Sensor network
with MODBUS and battery power
Category: Measurement and Instrumentation
Reference: 37425
The wireless sensors can transfer temperature, pressure, switching and other data to control rooms which operates under ControlMan Internet-based service. Any available GSM/TETRA networks may be used to transfer data. Visual presentation of information collected, reports for analysis can be viewed from any Web browser on any computer, so there is no need for separate control rooms and additional invesments. Wireless sensors powered by battery with replacing interval up to 10 years. Sensors core is an intelligent software which is able to manage the device networking and power-saving modes. Information transfer is bidirectional, so the output controls is also possible to apply. AutoLog Wireless Sensors are based on the 869 MHz radio technology. The sensors can be connected using MODBUS RTU protocol.
