I hope this is not the case, what a loss. [sadeyes]

hello, the site forums.coade.com seems to be down or offline starting a few days ago? Please advise.

In Canada, do the provinces regulate which software products may be used in the design/engineering of structures?

Hi, I am looking for the best book/article/handbook/website/etc. that is the best resource for piping stress engineering. Any comments appreciated. regards,

there would be an air dryer process upstream to drop the dew point.

hi, is it technically feasible to use a natural gas screw compressor (200 hp or 100 hp electric drive) for air compression? I will appreciate the help! thank you!

thank you gwalkerb. It would be a commercial facility.

hello, what is the applicable code to design of small diameter (3 inch) and short length (few hundred meters) piping with utility (fuel) natural gas and instrument air, in Canada? What does it depend on? thanks for any input.

At the flare tip, it is clear what purge rates to use, depending on the seal if it is velocity seal or molecular seal or just a utility flare. However, if there are a number of headers and subheaders in the relief system, each has to be purged, both at intermittent rates (e.g. during startup to...

Yes all go at the same time. The duration would be more than a few minutes. If I want to find the minimum height for the flares, the assumption of adding the radiations may not be the best assumption (too conservative). It seems to me that the presence of a flare nearby will pull the flames...

API 521 states: "The impact of multiple flares in proximity operating simultaneously needs to be considered when evaluating thermal radiation." What we have is a case of several flare stacks/risers in parallel in close proximity, so they are almost in the same location. The question is whether...

Biginch: I am a chemical engineer, not a mechanical engineer, doing some research, not any type or phase of design. In my projects we have installed Ethafoam successfully to manage expansion of pipelines with changes in temperature, this designed by certified stress engineers. Ethafoam is...

Littleinch Thanks for the input, we have not decided on anything yet, just looking at feasibility. Regards,

I do not think so, irony and sarcasm do not belong in any serious forum, as by nature they are potentially confusing and in some cases be also passive-agressive.

I do not think that irony is a way to make a point in this kind of forum. Anyway, Ethafoam is a product that may help in some situations to help deal with pipeline expansions, not all of them.

There is also the Ethafoam product from Dow.... http://www.qualityfoam.com/docs/ethafoam-220.pdf

This is a field pipeline, 15 km, in the tropics.

zdas04 Thank you, that is a good point.

Am I correct to suppose that the turndown ratio (capacity utilization) of 1. A two phase separator vessel 2. An three phase separator vessel is from 0-100%? In other words, they can operate at minimum capacity from 0 to 100% with no technical issues. This is about the vessel, I know that the...
