I reviewed some internal data for the GE-F7A gas turbine and it appears that as gtsim suspected, your T2 temperature is too low. Your T2 should be on the order of 804 to 806 deg F at sea level 14.67 psia. The PR which you supplied is consistent with the data that I have for that particular gas...
If you need to convert between normal cubic meters and standard cubic feet use the following conversion.
1 Nm3 @ 0 deg C & 1 atm => 37.326 standard ft3 @ 60 deg F & 1 atm
Mr. Ruby,
I am familar with running Merichem Treaters used to treat debutanizer bottoms, and straight run gasoline at an FCC.
If you're looking to control methyl mercaptans using a Caustic scrub, it's going to be important to control the levels of H2S in your gas stream. If your levels of H2S...
Bonzoboy,
The Rectisol is a Lurgi AG licensed acid gas removal system. A general rule of thumb is that a Rectisol AGR is going to be about 4x to 5x the cost of a Amine equivalent system.
I am guessing it is safe to assume that you'll be sending this SynGas stream to some sort of Methanation...
You may have another option if the filter is a stamped vessel. You may try to see if you can reclassify the vessel as ASME B31.3 piping. By reclassifying the filter as pipe, you would not need to provide a PSV to protect it. There are procedures available in API 510, and API 570 to determine if...
I researched this issue a bit as well for an FGD project as well. AWWA D100 is primarily a municipal water supply standard and is written as such. API-650 Welded Above Ground Storage Tanks is going to be the way to go for Limestone Storage Tanks.
gmorin do you work for Advatech/URS?

I have recently created a excel spreadsheet that models
how long it takes bare carbon steel pipes to freeze under
constant environmental and stagnant flow conditions. I chose water as my analysis fluid, and then created the calculations. The calculations will be used to determine
which plant...
If your lines are only going to be service water lines, e.g. hot/chilled water lines, which are to be buried you are probably better off simply using a FRP pipe. If you choose to go with a DI line, your best bet is to make sure that it's encased in a polyethylene liner, typically to about 8 mils...
First off what is the temperature of the cooling water return? This is the temperature that you have to take
into account. Generally Speaking you don't want to exceed
a cooling water return temperature of 65°C. Another drawback to PVC is it's durability in a industrial setting.
The best of...
I am searching for a standard that applies to underground FRP storage tanks as it pertains to Oil/Water Separators.
I found ASTM D4021-92 Glass Fiber Reinforced Polyester Underground Petroleum Storage tanks, but ASTM has withdrawn the standard.
Any leads to where I might be able to track down...
Actually some of the lines, are slurry lines, while the rest of the lines are comprised of process water lines, being pulled from the retention ponds near the plant.
The design considered the lines to be fully stagnant.
Freeze Protection Valves are definitely an item that we
are considering to...
Pmover,
Thanks for the info! you are absolutely right about those design parameters, unrealistic to say the least, considering the heating calculations for the plant buildings were based upon ASHRAE Dry Bulb Temps of 18°F and 23MPH. I am just looking for ball park, I have recrunched the numbers...
I have created a excel spreadsheet which simulates the time it takes to for both insulated and uninsulated pipes to freeze. The model is going to be used for an economic evaluation of whether or not a plant process water system will need to be electrically heat traced, and insulated. The...
