AB  - Membrane distillation (MD) has been increasingly explored for treatment of 
      various hyper saline waters, including lithium chloride (LiCl) solutions used in 
      liquid desiccant air-conditioning (LDAC) systems. In this study, the regeneration 
      of liquid desiccant LiCl solution by a pilot direct contact membrane distillation 
      (DCMD) process is assessed using computer simulation. Unlike previous 
      experimental investigations, the simulation allows to incorporate both 
      temperature and concentration polarisation effects in the analysis of heat and 
      mass transfer through the membrane, thus enabling the systematic assessment of 
      the pilot DCMD regeneration of the LiCl solution. The simulation results 
      demonstrate distinctive profiles of water flux, thermal efficiency, and LiCl 
      concentration along the membrane under cocurrent and counter-current flow modes, 
      and the pilot DCMD process under counter-current flow is superior to that under 
      cocurrent flow regarding the process thermal efficiency and LiCl concentration 
      enrichment. Moreover, for the pilot DCMD regeneration of LiCl solution under the 
      counter-current flow, the feed inlet temperature, LiCl concentration, and 
      especially the membrane leaf length exert profound impacts on the process 
      performance: the process water flux halves from 12 to 6 L/(m(2).h) whilst thermal 
      efficiency decreases by 20% from 0.46 to 0.37 when the membrane leaf length 
      increases from 0.5 to 1.5 m.
