Heat exchanger for 98% concentrated sulfuric acid at 40°C
Thread Content
Gentlemen, I have a heat exchanger whose hot-side fluid is 98% concentrated sulfuric acid, with a temperature drop from 40°C to 15°C, while the cold side uses circulating water at 9°C! The pressures on the cold side and the hot side are 0.3 MPa. What material is most cost-effective for use on the concentrated sulfuric acid side of the heat exchanger? I would appreciate it if experienced experts could advise me! Kneel in gratitude!
Do you have any examples of using super stainless steel like Sus321 in such working conditions? Brother, I need to use this material for manufacturing products, so your opinions are very important to me; please give them careful consideration
I’ve seen one with glass-lined shell side and tantalum tube side, of the bayonet tube type
In reality, there are quite a few of such heat exchangers, and the range of available materials is very wide. The purpose of replying is actually just one: to clarify the misunderstandings many people have regarding stainless steel. In fact, special types of stainless steel have always been suitable for use in heat exchange applications involving sulfuric acid. And the technology has been around for thirty or forty years.
For acid at 98 degrees and a temperature of 40 degrees, we use our Guangdong Nuoruide detachable plate heat exchangers made of C276 material. We have implemented this solution in many projects; feel free to contact Cao at 13922376553 for more information
For safety reasons, please use silicon carbide; it has a higher heat transfer coefficient than graphite, and there is existing successful engineering experience with it.
