What type of reactor is needed to withstand a positive pressure of 4 bar, when the reactants contain acids, and at high temperatures?
Thread Content
Hello everyone, the temperature needs to reach 250°C, and the pressure should be around 4 bar. The reactant is ACH 23 (a reaction of HCl with aluminum metal); is the medium acidic? ), what type of material should be chosen for the reactor? The capacity is not large; it’s only 1L, intended for use in the laboratory. Please, experts, give some advice.
I checked the manual; graphite and quartz glass work
The reactant ACH 23 (a reaction of HCL with aluminum metal) – the material specified by the customer contains HCL. Does the presence of hydrogen chloride mean that the medium is corrosive? Some suppliers say that titanium cannot be used as it is not resistant to corrosion. I’m completely confused now; I seek advice. What material is good? Is it necessary to check the HCL concentration with the customer?
Additionally, if the specified high temperature and pressure are reached, cannot a pH sensor be installed in the pressure vessel? Is it theoretically impossible to do so?
Titanium does not resist hydrochloric acid; it seems that glass-lined reactors cannot be used at this temperature. I can’t think of any suitable materials either. I’ll share more information once this issue is resolved
