I have a 316 stainless steel reactor. This reactor contains magnesium chloride (MgCl2) solution and a natural gas such as ethane or propane. Our temperature range is 15 to 68 degrees F. Pressure range is 20 to 150 bar. And maximum concentration of MgCl2 is 10% by weight. Our work is sensitive to impurities. Do I have worry about corrosion in this reactor?
Have an insight or suggestion?

Re: Do I have worry about corrosion in this reactor?4 November 2011 at 1:29pmTo evaluate this, one needs to know the chemistry and concentrations of the reactants and products including any impurities that are present or formed. Once this is known, you can start the assessment by looking up compatibility data for 316L stainless steel with the individual pure components to see if nay flags are raised. Even then, it could be difficult to make a corrosion assessment since mixtures sometimes behave in unpredictable ways from a corrosivity standpoint. In these situations it is often beneficial to run a corrosion study at lab scale to determine the corrosion rate and, in this case, whether low levels of corrosion products interfere with your process.
