What materials should be chosen for perchlorate and bromide ionic liquids?
Thread Content
The operating conditions are as follows: liquid temperature of 10–40 degrees, pH of 6–8, pressure of around 6–8 MPa, chloride ion concentration of about 40,000 mg/L, and bromide ion concentration of about 10,000 mg/L. I would like to ask the experts: can Ti10 be used in these conditions?
Patterned steel is simply carbon steel with medium and high levels of carbon mixed in. T10 is high-carbon steel. However, those with too high a carbon content tend to be brittle and hard. The most cost-effective and flexible option is the ordinary 65Mn. However, the materials mentioned above will all be corroded by chloride ions. Recommendation: Coat the parts in contact with the medium with polytetrafluoroethylene; ETFE or PTFE will work as well.
Sorry, I made a mistake; it’s TA10, titanium 10
The temperature is not high, but the pressure is high; the material of the container body should be metal, yet the inner wall can be coated with a material resistant to halide ions, such as enamel, PTFE, polyurethane, etc.
Due to the relatively high operating pressure, a composite plate (with a titanium layer on the inner side) or an inner layer coated with halide-resistant enamel, PTFE, etc., should be used.
Super duplex steel can be used; it should be quite ideal.
