Thanks for all the help, I appreciate it.

But technically it would pose any problems? Customer is asking for it to reduce size.

All right, I'm getting all this figured out. Thanks, just one more question. Are turbulators advisable on Amine coolers, or should the coolers be bare tube only?

Can someone please explain to me how a heat exchanger with Over one end recirculation works?

But isn't A516-70N non-killed material?

Thanks for the help. I'm trying to find ASTM A-515 Material though for the header design (normalized), and I've been told that it is incredibly difficult to find. Is this true? Could I just use Stainless Steel in lieu of the killed material?

Just another quick question for everyone. Would you use Carbon Steel over Stainless Steel for a lean amine cooler? Why?

Thanks maddocks. I'm just trying to see if the tubes can be easily manufactured being killed and normalized. The tubes will be seamless. I've been given an opportunity to quote a Sour (High H2S) gas cooler, which I've never done. Is this something I should just stay away from, or does it...

Ok, another question here. I have an engineer now asking if the materials are acceptable for amine service. Such as all materials, Carbon Steel, being killed and normalized. Is this common?

Thanks, what is the reasoning behind this? Is there erosion problem with the welded tubes?

Thanks, I really appreciate the help. I notice the Maximum Velocity value, but is there is a minimum velocity for lean amine? Also in response to maddocks, the customer is requiring SA-214 for the tube material, should I advise against this? And I always check the cold air horsepower draw, I...

I'm a fairly new mechanical/process engineer, and I have just a few questions. I'm working for an air-cooled heat exchanger manufacturer, I'll keep that one to myself, and we've recently got into the world of process cooling. I'm using HTRI to design my coolers and I take the process data from...
