I am a rookie engineer. Following are my questions that came to my head as I was reading (studying) a DWG (sketch really) for a Wash Water Drum involved in a refining project.
In a refining operation, what does Wash Water Drum do?
I see a corrosion allowance of 0.25" on the vessel - Is the...

In a refining operation, what does feed surge drum do?
What is blanketing gas? What is its purpose?
On a drawing (roungh sketch really) for a Feed surge drum I see a nozzle connection for steam out, but I dont see steam in - Is there something wrong? Or is it for the steam that is removed from...

can some one tell me what exactly is Sprayball Testing and why and where it is used? I came across it while browsing

as you will know from my question, I am rookie. I am reading a drawing of a surge drum on some processing plant. The drawing mentions a lot of nozzles and manways etc. I am trying to find the total weight of the total installation. Where can I find (ASME standards? appendices?) information about...
I burn some CFM of fuel (natural gas) in oven at some % excess air. Air comes in at some Relative humidity, temperature and pressure. Fuel comes in at some pressure and temperature.
Are their any tables that I can refer to, to decide flue gas temperature?
My flue gas in a commercial baking oven consists of a mixture of combustion products (CO2, N2, O2) and superheated steam (due to moisture removed from the feed in the baking process). In my current analysis, I am assuming properties of pure air to hold true for flue gases, but I guess if large...
I will like to direct your attention to the thread that I posted in a different forum. Instead of repeating my message and risking being kicked off this wonderful community, I thought I will just direct your attention to this thread. Please contribute if you can.

I am looking for for a co2 sensor that I can bury 1 feet in a pile of sand. I want to sensor to be robust against the dust problem. Are you aware of any such sensor in the market ? I have done a lot of looking but have not found a sensor that has some sort of shield to guard it against dust...
I am looking at steam table data for specific volume (ft3/lb) of superheated steam in the range 500 F to 1400 F. I am ok with data at 14.7 psi but I will like to incorporate the effect of variation of pressure. The variation is not much -- May be 2"wg at the most, do you think I should at all be...
I have written quite a few threads about the chimney stack + fan + oven problem that I am working on currently. Basically it is a natural gas oven, 20 feet of chimney stack + a variable speed fan at the end to control the excess air for the fuel combustion. We have an orifice in the chimney...
For SCFM purposes is temperature 70 F or 60 F?
I know crane 410 uses 60 F - I wonder why when most other places (HVAC books etc.) I see 70 F.
what is the most common? -- Or is this rookie missing something ?
I am looking for a formula for the pressure drop in an orifice. I know the flow rate through the duct in which orifice is fitted. My orifice is square edged. I was looking at CRANE Technical paper 410 - A-20 - But the geometry of orifice does not quite match with mine. I also looked at Handbook...

Can you please comment on the latest question? I believe that folks from this forum will have some good suggestions for me.
Thank you.
hi,
with a 20 foot chimney for our over we are getting too much excess air. We need to bring the excess air by about 300%. Is installing a fan system on the outlet of chimney the solution ? I was thinking with original chimney we have too much excess air -- that means we have enough draft. Isnt...
in a duct system of ours, we had a T fitting to allow for gas flow in perpendicular direction to the main flow direction. Then we decided not to allow that flow and hence we blanked the opening off using a wooden plank. But since it is not 100% air-tight, there is some resistance coeff...
