I went to a very interesting seminar on valves used in the oil and gas industry for high severity operations.

It concentrated on compressor recycle lines and flow line choke valves.

The subject matter covered included material selection, how to control flow rate, pressure differential, corrosion and erosion resistance, analysis of modes of failure and of course developing technologies. They use DRAG technology, which is essentially using a tungsten carbide filter to surround the valve plug on a globe valve in liquid stream to protect the plug from damage, excessive pressure drops and to remove any chance of cavitation. A picture of one of the discs that together with lots of other discs stacked together form the filter. The flow being from outside to in.

Surprisingly, it was not delivered as a sales pitch despite coming from a private company. I think that they know what they produce speaks for itself. I for one learned a huge amount and will be applying some of the lessons learned to my projects. It will be a way of ticking the new technology competency.

Mark, if PEW doesn’t work out you should consider it…
