Selecting Pressure Transmitters to Improve Centrifugal Compressor Safety & Efficiency

Overview Centrifugal compressors are widely used in the process and oil & gas industries. Correct transmitter selection is critical for these applications – in particular, anti-surge and throughput control. Unfortunately, many user practices are based not on quantifiable engineering methodologies, but on experience valid more than a decade ago, but now obsolete. The objective is to allow the user to improve on the all-too-common “surge-plus-10%” rule, substituting rigorous methodologies to quantify application requirements and system performance. The paper will explain how transmitter performance – especially response time and installed repeatability – affects compressor safety. Then, methodologies and tools will be presented which allow users to quickly and reliably estimate these parameters, allowing the user to minimize unnecessary energy cost, without increasing safety risk.

Peter Cochrane's Uncommon Sense: The oil crisis of 2003

The bad news is that it takes a decade to design, build and commission a nuclear power station. I can see a host of less significant problems looming in the coming decade/s but the technologies are waiting to be discovered and solutions to be created.

Hello? Yes, I'm under water

According to the DTI, the technology resulting from the research project should be invaluable to oceanographic and environmental monitoring and increase safety for professional divers working in the oil and gas industries.

Peter Cochrane's Blog: Unfair fallout

The threat of even more pollution from coal and oil - plus a dwindling oil supply - and the widespread untenable nature of renewable energy will see nuclear power as the only feasible alternative unless we are happy to see the lights go out.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
