Foam break-up under swirling flow in inlet cyclone and GLCC(C)

Experimental data are acquired on foam stability and break-up efficiency in a 0.025 and 0.05m inlet cyclones and a 0.05m GLCC compact separators. Additional data are collected in a 0.025m inlet cyclone on the effect of increasing surfactant concentrations on foam stability and break-up efficiency. The experimental results show that foam stability increases with increasing surfactant concentration, having an exponential decay effect on foam break-up efficiency in the cyclone. For the 0.05m inlet cyclone and GLCC, at low G, only negligible foam break-up occurs. On the other hand, at high G, higher foam break-up efficiency is achieved. Comparison of the foam break-up efficiency demonstrates a slightly better performance of the GLCC, as compared to the inlet cyclone.
