High-pressure reaction in a reactor
Thread Content
140 degrees Celsius, 2 MPa pressure, acidic environment – which type of reactor is suitable?
Temperature isn’t an issue; at such high pressures, the enamel-lined tank definitely won’t work – the enamel will crack. Stainless steel is the only option; if there are chloride ions, even 304 won’t work. At least it’s 904L
What acid is it? You need to specify the type of acid. Ordinary weak acids don’t pose too much of a problem for stainless steel, and since the temperature isn’t high, it’s mainly the pressure that’s an issue. But there are still 20-kilogram enamel reactors available
It also needs to be determined based on the concentration of sulfuric acid in your system! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
I disagree with your view. 2MPA glass-lined steel is no problem. The key issue is that the original poster doesn’t provide clear information, making it impossible to choose the material.
It is recommended to use an enamel-lined reaction kettle; a pressure of 20 kilograms is not considered very high, but the cost of enamel is relatively high
There are now stainless steel reaction kettles made of composite materials, which are also high-pressure! The price is still quite reasonable
