Rockwell Presents Oil And Gas Control Systems

Rockwell Automation will be highlighting its digital field and integrated control, power and safety solutions and services for platform and subsea control at the Offshore Technology Conference (OTC). The Rockwell Automation OTC 2010 booth will outline the company's solutions and global support capabilities for the oil and gas industry. A process control centre featuring the Rockwell Automation Plantpax process automation system will be on display, featuring a critical control and safety system that enables the user to specify the level of reliability and availability needed for operational excellence.

The booth also will feature an IEC-compliant motor control centre that offers protection for personnel and equipment. According to Rockwell, digital field solutions help oil and gas companies obtain high performance and value from their assets, including asset performance management (APM) solutions. Rockwell Automation APM solutions utilise the company's Factorytalk Vantagepoint EMI (Enterprise Manufacturing Intelligence) software to provide role-based visualisation, analytics and reporting that can help improve production and asset surveillance.

In addition, Rockwell Automation will highlight its Software CEM system, a continuous emissions monitoring system (CEMS) and real-time environmental management technology. These are said to provide accuracy and reliability at a lower total cost and are designed to help ease compliance to state and federal environmental protection agency requirements. The company will also offer additional information and hands-on demonstrations of the technology and solutions described above.

Ecosure Sensor Detects Leaking Carbon-Monoxide Gas

City Technology's Ecosure electrochemical sensor detects the silent escape of invisible carbon-monoxide gas from faulty or badly adjusted heating devices. Ecosure is the sensor of choice for the majority of carbon-monoxide detector manufacturers because of its performance, stability, reliability and extended operational life. It is also used in multi-sensor fire detectors to improve their detection reliability and reduce their false alarm rates.

Ecosure is a two-wire electrochemical sensor with inbuilt filtering that protects it from poisons, interfering gases and dust, minimising the possibility of false alarms. Its stability means that instrument manufacturers do not have to provide complex compensation circuitry. The sensors are manufactured in an automated manufacturing facility and comprehensively tested at each intermediate stage during the production process. As a result, the standard deviation in the output of individual sensors is extremely small, again enabling instrument manufacturers to simplify their instrument designs, thereby reducing time to market and improving manufacturability.

In addition to its stability and false-alarm immunity, the sensor quickly responds to the presence of carbon monoxide, reaching T90 in less than 20 seconds. It is mechanically robust, can be installed in any orientation without affecting performance and operates from -10C to +50C with continuous relative humidity ranging from 15 to 90 per cent. More than 10 million households rely on Ecosure.

City Technology Enhances Hydride Gas Sensors

City Technology has enhanced and extended its Sensoric range of hydride exotic gas sensors. These sensors all use an ionic liquid electrolyte to provide improved output level stability, responsiveness and overall performance improvements in the aggressive environments in which they operate.

The new arsine and silane sensors are improved versions of existing gel-based devices, and three new sensors, characterised to detect phosphine, diborane and hydrogen selenide, have also been introduced.

According to City Technology, the ionic liquid combination has excellent thermal stability with no measurable vapour pressure, offering results even when subjected to wide variations in operating temperature, relative humidity and gas flow rates.
