Chemical compatibility tables

Chemical compatibility tables

Chemical compatibility tables

(OP)
Hi there,

Can somebody please tell me where I can get useful information on the compatibitily of chemicals. E.g. at the moment I'm looking at putting these into the same pipeline:
1.8 m3/week of 10% HCl,
0.7m3/week of a mixture of 30% HNO3/1.5% H202 and 0.1% Ni
0.032 m3/week of 15% sulphuric acid

I know the piping manufacturer can supply me with info on whether their piping material is compabible.  However, do I need to do lab tests myself to investigate any increase in temperature due to reaction of these.  What is good practise?

Thanks in advance,
Chemenv.

RE: Chemical compatibility tables

Are you running these chemicals in the same pipe together?  Having HCl and HNO3 in the same pipe will make aqua regia which will eat up a good number of materials.  Whenever we order pipes or hoses for production we just consult with the supplier like you mentioned.  They have probably already done the research on common materials like you are talking about.  I assume you will be using some kind of teflon lined pipeline since you are running HCl through it.  I would think that would withstand any of those acids with no problem.
