Hello all, thanks for taking the time to read this. I am a mechanical engineer at a power plant and we are looking into using Activated Carbon products to remove wastes from our flue gas. We are looking for a method to test the incoming bulk carbon for consistent reactivity and while I have...

The closest solution I have seen was in south Texas where the plant had ALL of the piping in trenches. The trench was dug ~3' with concrete walls/bottom and every stick of piping was laid down in the bottom. Handrails were erected everywhere it wasn't determined necessary for a crossing and...

This really seems like it could be a great idea, basically a garbage incenerator on steroids without all the emissions. Looks like there is probably still a concern for the solid waste on the back end which is always going to be a problem. There isn't anything out there that can make EVERY...

ash060, I can definately relate to that. My main cause for this exact same tendancy was lack of any immediate deadlines. I had 4 different projects assigned to me that were each worth a few million dollars but were 2-3 year lead times. While I had items I could do on each none were that...

Plain and simple - Interviewers should get some sleep the night before too. Went into the interview with 3 interviewers who all had the same sheet of questions. They went round and round the table, each asking the next question on the list. The 3rd guy was interesting though, he fell asleep...

Don't know too much about using it to break freezes but from what I have researched for my company's uses of anhydrous ammonia is that when you add water to it the chemical reaction generates excessive heat. The thought could be to get it to the frozen section, let it interact, and the more...

Spike, All the power plants that I know of base what they will pay for a alternate fuel off of $/mmBTU. So if you know the BTU/lb you should be able to get a good ballpark on what kind of revenue you can generate. The biggest problem that I have seen is shipping. 250 tons is ~10 truckloads a...

Actually the correct argument's phrase is "For the love of money is the root of all evil" therefore it would seem to me that the interpretation is greed is evil and not money itself. Again a misquoted passage over time turned to mean something else. So I guess this would evolve to if the...

0707 - WEO = Nice idea but in all reality it would be a pipe dream. The UN can't enforce a sanction against any country anytime for anything so what measures would the WEO be able to enforce? Stern letters, harsh language? The world seems to be unable to come to a consensus on what to do with...

I am also giving my view point on student engineers that we have had at the plant. I agree with epoisses on the advantages for both sides but from what I have seen here at my plant the last line is most important. There has to be a clear person in charge of what the intern is doing, how much...

To start off I have searched numerous different keywords on "Google" etc and contacted many reps, suppliers, and manufacturers but with no luck. We are looking for larger (~24") rotary airlocks (or rotary valves or star valves) with a mechanical cleanout device that scrapes out the pockets as...

I could see this having greater potential for trans-oceanic cargo flights. The length of those flights and the reduced population below the planes would probably be the most practical. Just my two cents. Regards, EOIT

I would repost this under the HVAC/R Engineering section of "Mechanical Engineering" to get a better response. Furthermore some explaination would be helpful. Amount of air, size of duct, etc whatever can be disclosed. Regards, EOIT

I work at a power plant and the original asphalt roads used during construction and operation lasted about 15 years before major repairs were needed. And those repairs were really only in the high traffic areas for loaded semis etc.

Hello All, We are going to weld a temporary wide flange beam to existing structural steel for an overhead trolley system. It will either be catalivered or simple suppoted at two fixed points or a combination of both. I have the calculations for the deflection of either support setup and the...

Thanks for the info so far ya'll. We have settled in on the phosphorescent in the system since that will be unobtrusive and fairly inexpensive. Still looking to see if anyone knows about how long it would take for the chemical to 'seep' to the surface. I have spoken with the company and they...

I work at a power plant and we have had a steady leak underground for quite sometime and since I am the new engineer they want me to take a crack at it. The area with the leak has 8 pipes running through it and we would like to try to narrow down the ones we should look at. We can isolate...

Try workintexas.com it is a website specifically for jobs in texas posted by employers, etc. I have found a couple good ones including my current one. Also the Dalls Morning News posts all the jobs from their classifieds as well.

To put more of an engineering perspective on things, managers hardly get to 'engineer' much once they get to the higher levels. Sure they can guide those below them, but with the paperwork, personnel issues, reports, etc to do, the Engineer side goes away and that life takes over. My boss is a...

I work at an older power plant with several outdoor water storage tanks on site. Near one of these tanks we have developed a large puddle ~ 8 ft around and 1 ft at its deepest point. At first we thought there was a leaky valve contributing to the accumulation of water, but after securing the...
