Lean Amine Cooler
Lean Amine Cooler
(OP)
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 chemical engineers, and then size the appropriate cooler for temp, heat load, phase, pressure drop, etc etc.
I just have a quick question for all of you experts here. I've been seeing a lot of Lean Amine and Propane coolers, are there any things that I should keep in mind when designing these coolers, such as certain fluid velocity or anything that I'm not thiking of. Any advice would be greatly appreciated.

Because of northern climate, be sure and check your cold air horsepower draw and you can option in full warm air recirc systems.

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 do a lot of designs for Siberia.

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 just take a few extra precautions.

Carbon is usually adequate for lean coolers - the partial pressure is fairly low and the loading low. Given that there's no gas breakout and no acid gas attack, carbon is a pretty good choice.

Are turbulators advisable on Amine coolers, or should the coolers be bare tube only?
