More resistant chromium-nickel grades can be passivated in a 20 percent-by-volume nitric acid bath . As indicated in the same table, less resistant stainless grades can be passivated by adding sodium dichromate to the nitric acid bath to make the solution more oxidizing and capable of forming a passive film on the surface.

Another option, used in place of nitric acid plus sodium dichromate, is to increase the concentration of nitric acid to 50 percent-by-volume , The sodium dichromate addition and lit : higher nitric acid concentration both reduce the chance of undesirable flash attack.

General-purpose antifoams have a wide range of applicability, but not all of them are suitable for use in the treatment of gas. Some foam control agents can aggravate the problem. Foam control in gas scrubbers is only one of the process parameters to be monitored. It is equally important to prevent or slow the fouling of the unit, because dismantling of the gas-scrubbing units is manually intensive. Incorrectly specified antifoams can easily lead to increased fouling and clogging, particularly in the heat exchangers. Momentive Performance Materials RXSOL antifoams are designed to provide foam control with a minimum of such problems.

Antifoam Defoamer is a cost-effective and economical defoamer designed for a wide range of food-grade and food processing applications as well as general industrial applications in paper making, textiles, paints and coatings, and anywhere foam is an issue. To determine the required amount of antifoam for your specific application, begin with 100 ppm and adjust the levels down to determine the optimum use level. For food applications, do not exceed 100 ppm. Pre-dilution provides a way to manage performance and economy for most applications. Antifoam Defoamer is very Dilution Stable to levels below 2%
