Water vapour absorption in conical sheets of aqueous lithium bromide solution.

Author(s) : PALACIOS E., IZQUIERDO M., LIZARTE R., et al.

Summary

This work focuses on exploring the feasibility to use conical solution sheets for refrigerant vapour absorption. Experimental measurements were carried out spraying an aqueous lithium bromide solution with a hollow cone type commercial nozzle into a water vapour atmosphere. The atmosphere pressure range tested was 1.0-2.2 kPa and the solution flow rate range tested was 28-47 kg/h. It was observed that the absorption process was over at about 200 mm downstream of solution injection. However, about 60% of the process was been carried out on sheet disintegration at 40 mm downstream, that is, at about 4 ms after solution injection. Additionally, experiments evidenced that sheet deformation assisted the vapour absorption. Hence, the vapour absorbed per solution flow rate was more than 10% on sheet disintegration at a flow rate of 40 kg/h as compared with that at a flow rate of 30 kg/h. Conversely, the participation in the absorption of the droplets population generated at sheet disintegration decreased with the flow rate.
