I am installing an automated isolation valve to protect a sulfuric acid control valve (after isolation valve) from deteriorating by acting as an isolation valve as well as a pH control valve. Before I automate a handvalve, what things do I need to consider in programming or design of that...
We were in a start up an shutdown situation so velocities could have ranged from 0 to ~12ft/s. We can do thickness testing with some of our reliability equipment and will schedule for the near future. Until then, what would be a good rule of thumb for Cl and SO4 concentrations for the...
Would you guys know the level of Chlorides/Sulfates that is allowable in a stream in 316 SS L piping that has the following characteristics:
1) temps up to 180 deg. F
2) pH~ 1-2 due to an aqueous solution with lactic acid
3) pipe velocities up to 12 feet/s
We had a chloride excursion at our...
