I've always believed that if you work hard and never stop learning that the money will take care of itself. Having a job that you enjoy is worth a lot.
A good rule of thumb is found in Lieberman's book, "Process Design for Reliable Operations" he brings up the relationship that U=v^0.7. U is in Btu/hr/ft2/F, v is ft/s.
I agree with djack, if it's a large change in velocity, I'd use a detailed rating program like Aspen's HTFS.
What is the temperature of the fluid entering the reboiler? What is the required exit temperature of the reboiler? What temperature is the hot oil available at? Is there a minimum hot oil outlet temperature? What is the flow of the fluid to the reboiler and what are its physical properties...
You should start by looking at the interactive forces among the molecules (London, van der waal, hydrogen bonding). Viscosity is a strange property in that it doesn't always trend like you'd expect, especially among various types of molecules.
I think this book might have some of the answers...
In reality the glycol temperature feeding the contactor does not make a difference. The mass flow of the gas is so much higher than the mass flow of the glycol. Once the glycol hits the tower it will immediately reach the temperature of the gas at the top of the tower.
"Metallurgy for the Non-Metallurgist" looks like exactly what I was searching for. Thanks.
I can't seem to find any mention of "Engineering Metallurgy" on the web. Where can I get a hold of it?
I'm a chemical engineer in the oil & gas industry with limited knowledge of petroleum processing metallurgy. I'm specifically interested in the grades of carbon and stainless steels.
I hear different grades discussed often but I'm unfamiliar with their properties or how one grade of steel may...
Thanks for the good information. I'm sorry the original post wasn't clear enough, but the information provided gives me enough information to solve my problem.
I have a multi-stage centrifigual compressor. Natural gas (approx 85% methane) is being compressed from 700 to 1300 psig. Lubricated labyrinth seals are used in the compressor. The lubrication comes from a lube oil tank with a MAWP of 15 psig. The lube oil tank has a 3" NPS line venting to...
