People,
I want to use a 3" Class 1500 Globe valve on the following service:
80% Co2 - 20% Methane
Design Pressure: 150 Barg
Design temperature: -10C to 120C
Onshore application
If I want to use SS trim and body, the valve would be very expensive; however I know my best bet is to use 316 for...
People,
Do you know if it is a requirement that the distance between the compressor surge connection take off from the discharge line and the discharge check valve to be minimum? If so, what is the standard?
Regards,
Diego
All,
I have done a Solar Turbine course and I am wondering if anyone can recommend a good book regarding the compressors and turbines as a study/refreshment book.

Hi All,
Does anyone know if there is a safety zone when performing pneumatic testing? I couldn't find anything in Asme B31.3.
Any feedback is appreciated.

Guys,
Is there anyone who can provide a guideline on frequency of sampling of the corrosion probes at the plant inlet and slug catcher in a sweet natural gas plant?
Thanks
Gents,
Could a expert person please verify the following?
The maximum operating pressure VS minimum temperature (0C) of carbon steel piping A106 Gr.B of class 300# is 51 Barg. I believe this is the maximum operating pressure of the 300# flanged vlave in a closed position in order to not stuff...
Guys,
Can anyone of you know about this?
Which of the following RTG (2R) gaskets are suitable to fit between SS PSV flange and CS ball valve flange? Piping classes are 900 and 1500#.
1- RTG Gasket, 316SS Hardness below BH 160
2- RTG Gasket, 5Cr-0.5Mo (F5) Hardness below BH 130
Guys,
We recently had a problem with the condensate fin fan cooler on our plant. It tripped several times due to high temperature (75 C). The thing is it is intended to cool condensate but for whatever reason we get MEG (Mono Ethylene Glycol)and emulsion in there too. We removed a few plugs and...

Hi Guys,
We have 4 bottles of odourant on site. Nitrogen blanketing line is supplied with 100 KPag to each bottle. The distance between bottles to the odourant cabinet where 4 high pressure pumps are, is nearly 3 meters. Recently we had the problem of pump lock due to vapour existence in the...
This question might have a simple answer I do not know. Why where there is a high pressure drop across a PSV or PCV, they inject glycol or methanol upstream of the device?
Gents,
I have a 2 diesel PSVs DS of a pump to protect the pump. One of them is open to Atmosphere with the set pressure of 500 KPag and the other is piped to diesel tank with the set pressure of 300 KPag. Now I want to connect the open to atm. PSV to the other PSV (300 KPag) outlet line. The...
Guys,
There is an air cooled exchanger in our plant (Hudson Hei) for cooling down hot oil service. Recently we has a problem of theis unit trip due to high vibration. We are used to get a vibration company does equipment condition monitoring for us and he advise to check the condition of drive...

The cooler is currently operating with noise.
