The Effect of Salt on Stability of Aqueous Foams

The properties of foams are often affected by environmental variables such as salt contamination. objective this study is to investigate the impact on drainage behavior aqueous foams. To accomplish objective, experiments were conducted Test foam quality (40–65%), and content (0% 18%), type. drainage, was generated in a flow loop trapped vertical test section. Then, pressure profile column measured using ten sensors. Foam determined function time profiles. results show that NaCl-containing decreased with quality, whereas CaCl2-containing did not exhibit clear trend quality. effect rheology minimal.
