Heavy fuel checker launched
Turbison Heavy Fuel instrument undertakes oil stability checks in 15 minutes
The French company Formulaction, specializing in the development and sales of instruments for analysis of concentrated dispersions, is launching a new instrument, Turbiscan Heavy Fuel. The device was designed in collaboration with The Associated Octel (UK), a company manufacturing additives. The instrument complies with the ASTM D7061-04 for measuring heavy fuel oil stability. Over recent years several methods have been developed, but these analyses remain time-consuming, subjective and tedious. Turbiscan Heavy Fuel is the first instrument providing an objective, repeatable and accurate measurement of asphaltene stability in heavy fuel oils.
Reduction in the quality of crude oil throughout the world, due to diminishing resources and increasing refinery efficiency, have led to a deterioration in heavy fuel oils quality. Asphaltenes – a mixture of heavy hydrocarbons – tend to precipitate depending on the nature of solvents in which they are contained. The result is blocked pipework, clogged filters or plugged burners. Extraction sites, refineries and heavy fuel oil users (marine companies and electrical power plants) are therefore obligated to systematically test the heavy fuel oils’ stability in order to improve efficiency of their processes.
The ASTM compliant Turbiscan Heavy Fuel device enables measurement of heavy fuel oil’s stability reserve in 15 minutes. This parameter quantifies the capacity of asphaltenes to precipitate and settle within a fuel oil. It allows the accurate optimization of the concentration of additives to be added to optimize the stability of the fuel.
The technology can also have other applications within the petroleum field, such as de-emulsification of water-in-oil emulsions during extraction processes, stability of drilling fluids or any other applications in which the stability or destabilization of dispersed systems need to be monitored.
The Turbiscan range of devices combine the multiple light scattering measurement to a vertical scanning of the product analyzed. This scanning enables the identification and quantification of localized destabilization phenomena (creaming, sedimentation, clarification, etc.). Furthermore, the measurement is sensitive to variations in size, allowing associated instabilities to be identified e.g. coalescence, aggregation, flocculation.
Electro Industries/GaugeTech has recently launched the new Shark 100 Digital Power Transducer.
This low cost digital transducer measures 3-phase voltage, current and power and provides a hi-speed RS485 digital output using Modbus or DNP 3.0 protocols.
The unit’s small footprint and simple installation make it the ideal solution for embedded power telemetry for industrial, OEM and utility applications.
The unit is designed to mount to a DIN rail and offer a 120/220 AC or DC power supply. Low voltage 24-48 VDC power supply is also available.
Float level switch makes waves
K-TEK, a manufacturer of state-of-the-art level instrumentation for liquid and bulk solids detection, has announced the launch of the MS50, the latest version of the company’s low cost float level switch.
K-TEK’s MS50 float level switch is approved for use in hazardous areas
The MS50 is designed to reliably handle a wide range of applications, including sump level control, alarms, and shutdowns.
Each switch features application-specific float designs that optimize performance and reliability in the fluid being measured, whether butane, propane, oil, acid, water, or interfaces between two fluids. A unique magnetic coupling ensures optimal switch performance throughout the life of the unit. The MS50 can be equipped with up to six SPDT switch points per unit. For maximum up-time, a K-TEK latching switch design allows each point to be adjusted and replaced in the field.
The MS50 is FM Approved and CSA Certified for use in hazardous areas. A high temperature option handles process temperatures up to 149°C. For high vibration/shock applications, such as transportation, a multi-float option uses special non-latching reed switches and stop collars to guarantee reliable switching.
“K-TEK’s switches are designed for the needs of today’s production operations, maximizing flexibility and minimizing down-time,” said Kevin Hambrice, director of marketing, K-TEK. “The MS50 can be adjusted in the field, without removing the vessel from service. And K-TEK’s broad range of float designs ensures a match for the specific gravity of virtually any fluid. Competitive float switches are limited to only a few available float designs, mounting configurations, and measuring lengths. They must be pre-configured in the factory and are designed such that if one contact fails, the entire unit must be replaced.”
Each MS50 features an application-specific float design optimized for the specific gravity of the fluid being measured. K-TEK provides the largest selection of float designs, including 14 standard and hundreds of custom options.
External relays are optionally available for the MS50. The IR10 Interposing Relay Output Module is designed for process control equipment that may require a higher operating current than can be provided by most switches.
The PP10 Latching Relay provides control of on/off devices, such as motors, motor starters, solenoids, and alarms. Both units are easily mounted and installed. Each is supplied in an explosion-proof enclosure with terminal blocks for fast access to field wiring. K-TEK says its new product is competitively priced.
LOAD finds problems
Digital Inspections has launched a new software module designed to allow utilities to maximize electrical transmission capacity on their lines. The company, which is a pioneer in utility equipment health systems, has introduced Line Optimization and Analysis Database (LOAD) as a new product directed to the transmission and distribution organizations within the utilities industry.
LOAD is a unique programme that factors actual data from line equipment with anticipated variables such as climate and time limits to target which element within a line is the bottleneck for ampacity. By defining a transmission or distribution line and all its associated equipment, creating a thermal ratings standard, and selecting the environmental conditions within LOAD, factors that limit increases in capacity can be identified.

First field trial for fuel cell appliance
Ceramic Fuel Cells Limited (CFCL) and Central Gippsland Institute of TAFE (GippsTAFE) have announced their agreement for Australia’s first field trial of a fuel cell powered micro-CHP generator appliance.
The prototype trial will be conducted at GippsTAFE’s Chadstone campus in Melbourne’s south-east, by the company’s subsidiary Energy and Telecommunications Training Australia (ETTA). The trial will also utilise the expertize developed by GippsTAFE in its long association with the Latrobe Valley electricity generation industry.
Julian Dinsdale, executive chairman of CFCL said: “We are pleased that the first Australian site for testing and monitoring of our fuel cell powered prototype micro-CHP unit will be with a leading energy industry training institution.
“It is an ideal match for us to work with people in energy utilities, showing them the features of two emerging and sophisticated technologies – fuel cells and micro-CHP.”
CFCL’s fuel cell units are designed to provide efficient, reliable, constant and environmentally-friendly mini-generators on site in homes, offices and farms, thereby reducing reliance on large, centralized electricity generators and transmission and distribution networks. The units currently use natural gas, and have the potential to use renewable fuels such as ethanol or biogas, according to Dinsdale.
“Our prototype micro-CHP units are expected to be extremely efficient,” says Dinsdale. The field trial is for an initial period of three months and may be extended by agreement.
