The client did request ANSI, therefore it is our job to confirm that will be acceptable (which we have, and it is).

I agree with the safety aspect. It is traditional that refinerty operations use API pumps just because of that reason. However, a fueling terminal is not at high risk for fires. In most cases, the pump suction can be (and is most likely part of the operation) isolated by an automated control...

Anyone know of a good calculator for estimating electric tracing loads and insulation combinations in piping?

Thanks Juan, can you answer a question about the spreadsheet...what kind of crazy unit is the density and conductivity given in? Also, I do not see the latent heat values for phase changes... Looks like a good sheet thought...are you familiar with how it works? Can you add fluids knowing the...

Anyone know where a good source online would be for latent heat values of various materials, namely oils? Thanks

Being an engineer myself, I like to CMyA sometimes. But, in this case, I think it's a little extreme. I am hoping to get some opinions from others to confirm that, or learn something that will change my mind. I don't want our client paying 3-4 times the cost unless it is going to benefit...

I'm sure this has been addressed previously, but wanted to know if anyone could help me out quickly.... I'm working on a project for a gasoline/fuel oil terminal, where fuel is delivered to tanks via a pipeline and pumped from the tanks to tanker trucks for delivery. We are adding new tanks...

Pleckner, You have touch on just what I am looking for. Montemayor, your suggestion is exactly what I have seen in the past also, and look to do with this app. However, I have quite a distance from my three sources of steam (HP, IP, & LP) The LP steam will never make it, only 15 psia. IP...

Does anyone have experience with heating fuel oil in bulk storage tanks? I have an application where steam coils are used to heat fuel oils (#2 to #6), so they do not gel at low temperatures. I need to calculate the maximum steam temperature to which I can deliver to the heating coils such that...

Yes, I have an idea of temperatures to be maintained...question is the method. Need some details on how the tanker cars are heated.

I did the same search, brought up the same hits...none have specs on tanker cars. Fuel oil will definately gel in northern climates, especially when we are talking near Canada. That's why they have heating coils and insulation. Just need to get a general idea of how these cars are heated...

I'm looking into transporting either biodiesel or petrodiesel by truck or rail in cold climates. Is anyone aware of how these vessels are heated to prevent gelling? I would assume electric traced, but not sure. They may possibly be insulated only, but I'm not sure. Links to a website or some...

Ok, I'm no chemist, but I'm burning natural gas and fuel oil. Any ideas?

Found it. Relation between intensity and distance is the inverse of the distance squared. Any clues for the emisivity factor for a flame? Would it depend on the fuel? Thanks.

I am trying to determine the quantity of thermal radiation from a flame. Also, more importantly, I'm trying to determine the radiant load as a function of distance from an object (i.e. don't want to burn up something near the flame). Does anyone know the relationship between thermal radiation...
