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...

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 Recycle K. O. Drum involved in a refining project. In a refining operation, what does Recycle K. O. Drum do? I see a 12" manway on the DWG - Is it physically possible...

I am a rookie engineer. Following are my questions that came to my head as I was reading (studying) a DWG (sketch really) for an Effluent Seperator involved in a refining project. In a refining operation, what does Effluent Seperator do? Why is the corrosion allowance for vessel is 0.125, and...

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...

I am not responsible - I am a rookie and no one is going to make me responsible for this huge project. I am involved in the process as a mechanical engineer. As I work everyday, I learn new things - But what I want is an account of the whole process - may be briefly - I am sorry for posing a...

An oil company has hired an engineering firm to revamp a particular site. The job involves installation of several new pressure vessels, distillation trays .. on an on .. Now an order has been placed to a fabricator in fabricate a new and huge stripper tower. I will like to hear you comments /...

can some one tell me what exactly is Sprayball Testing and why and where it is used? I came across it while browsing http://www.psitanks.com/spraybal.htm

Also can you please tell me what is: % of System Limitation Entrainment as % of liquid load Tray Weeping (lb/hr)

can some one explain to me what the following terms mean? I have given my understanding. Please correct me if i am wrong. Max Tray Pressure Drop across entire column (psi) with the trays installedi in the tank, what is the max pressure drop? But I wonder what flow conditions this pressure drop...

I am trying to read up some introductory stuff about trays used in refinery applications, Hydrotreater etc. Any suggestions?

Thanks for the explaination, although I dont think I was not understanding the case wrong. Since flue gas temperature is around 800 F, what I am saying is the moisture part of the flue gas is in a superheated state. or say 20% fraction by volume of flue is superheated steam - I dont that is...

so is the very fine (micro) particulate matter always white? Is all abrasive material always white? is it true that the surface will always look white irrespective of the type of the abrasive material that you use.

can some one tell me why metal turns white when it is sand blasted? - I was just curious since I was quite amazed to see it.

thank you. JT: you are the best. I will now dig in and try to get my hands on all this stuff. I do have a good mentor, but as you can imagine he is busy :)

thank you all for your notes. All of them were very useful. As you know, I am just getting started. I am currently reviewing some design calcs for a vacuum tower. As I go through the document, I dont understand 10% of the things - Which makes it a little frustrating. What are some of the...

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...

EdStainless (Materials) The link that you provided does not work for steam. It is only for water. I am looking for data on physical properties of steam from 200 F to about 1000 F

concentration range: 300 ppm to 10000 ppm temperature: 50 F to upto 140 F

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...
