I would like help on calculating the likely thermal expansion of a gas compressor suction drum vessel during normal operation. The vessel is roughly 3mx2m and will operate at 26.3 barg and 43.5 degrees C. It currently clashes with a steel beam and i need to work out what the minimum acceptable...

Forum469 assumes right. The gas must be dehydrated so no water will drop out in the pipeline and form into hydrates. As the gas travels down the pipeline, it will experience changes in temperature and a drop in pressure that increases with distance travelled. Many subsea pipelines place the...

Olaya, thanks for your reply. I would be very interested to know the names of some companies that can do tests and find a suitable demulsifier. We have a number of samples of the current emulsion - the exact concentration is being analysed, but visually, we have a bottle of full cream milk...

I am involved in an issue regarding the formation of an emulsion on a gas production platform. Currently, an emulsion forms downstream of the production separator due to oil carry-under with the produced water which is accelarated through a Pressure Control Valve. It is believed that the...

I am involved in an issue regarding the formation of an emulsion on a gas production platform. Currently, an emulsion forms downstream of the production separator due to high oil carry-under with the produced water being accelarated through the Pressure Control Valve. We are in the process...

I am dealing with an oil in water problem for an offshore gas rig. We appear to have an emulsion forming at the production seperator PCV. This emulsion then appears to travel all the way to the water skimmer. New pure condensate, and condi/water streams meet this emulsion stream on the way...

I am quite new to instrument diagrams but have developed a good knowledge of process control so I know what all the various valves and indicators are for, I just have not been able to find out what all the abbreviated labels actually stand for, so i was hoping someone could help. A list is...
