GAS COMPATIBILITY TECHNICAL INFORMATION

140 ADVANCED Specialty Gas Equipment TECHNICAL INFORMATION GAS COMPATIBILITY The compatibility data* shown on the following pages has been compiled to assist in evaluating the appropriate materials to use in handling various gases. It is extremely important that all gas control equipment be compatible with the gas being passed through it.

  Technical

Gas- Liquid and Gas –Liquid –Solid Reactions

1. A stagnant layer exists in both the gas and the liquid phases. 2. The stagnant layers or films have negligible capacitance and hence a local steady-state exists. 3. Concentration gradients in the film are one-dimensional. 4. Local equilibrium exists between the the gas and liquid phases as the gas-liquid interface 5.
