摘要:
There are several methods to perform experimental measurements of the overall gas hold-up in bubble columns but none of them is considered to be a standard method for measuring this parameter The precision of measurements lies between 10-20%, and improvements to increase it for any of these methods are welcomed. This work presents improvements to liquid height variation method. Experimental measurements of gas hold-lip in a bubble column are correlated with flow regimes and bubble size distribution in a bubble column with porous plate gas distribution device.
