Preventing harmonic currents from flowing through a power system is the best way to ensure clean voltage waveforms essential for the correct operation of process equipment. Drawworks applications can be very demanding on encoders, with continual vibration, high shock and ever-present dirt, debris, oil and moisture. With the increased use of the internet for electronic data and information, Duoline Technologies is providing internet users with an interactive website for gathering of information related to its oilfield corrosion solving products and services. Anixter Components’ new range of ATEX-approved cable glands for use in hazardous locations (type ‘e’ or ‘d’ according to EN50014, EN50018 and EN50019). The glands fix cables securely in place and are suitable for applications in potentially hazardous areas, including machine apparatus and plant equipment, control and feedback systems. While investment opportunities still exist in the liquefied natural gas (LNG) sector of the Russian energy industry for the construction of gas liquefaction plants, the government has turned its focus on the nuclear power generation sector. The new ISO 14121-1:2007 standard covering risk assessment for machinery will help designers and manufacturers reduce associated safety hazards. Initial choice of gas turbine equipment should be based on achieving the lowest life cycle cost rather than the lowest installation capital cost, writes Dr Ken Ramsden Technique uses infrared online analaysis to give real-time monitoring promises to boost process optimisation

Total E&P UK, one of the largest exploration and production subsidiaries of the Total Group has installed a 10000point+CitectSCADA system to provide monitoring – with full dual redundancy – of the control and safety systems for the giant St Fergus gas terminal in Scotland.

Imagine developing a highly complex piece of electronics engineering that can communicate huge amounts of data across long distances, undertake complex analyses of material and guide machinery in a specific direction.

In the logging and production environments there are plenty of measurements that use a type of rotary position sensor called an optical encoder. Since encoders are measuring rotary movement, they must have a means to provide a rotary environmental seal against a rotating shaft. Thermal imaging cameras offer solutions to some difficult problems. With the ability to ‘see’ in total darkness, through mist or fog and with excellent contrast and sensitivity, thermal imaging camera stations can be used for a variety of duties; security, surveillance, navigation and process monitoring. Conventional infrared wavelength generation technologies present significant downfalls when it comes to the measurement of hydrocarbon gases in the process environment Alain Hubrecht reports on how cost reduction is forcing corporations to reuse their knowledge and minimise data replication. Siemens Automation and Drives has developed two telecontrol systems based on high-speed, low-cost GPRS (general packet radio services) data transmission. next
