The gas-liquid system is an interesting subject in the field of chemical engineering. Here, sulfur at thetemperature of 140°C was considered as the liquid phase, and nitrogen gas was distributed inside it byusing porous spargers. Results showed that the sparger, which possessed higher surface area could generatehigher gas holdup in the liquid sulfur. This was attributed to the formation of finer bubbles in the same gasvelocity. The gas holdup was measured by using level difference and image recording techniques.
