英文摘要	During operation of evaporators of cryogenic liquids, moisture freezes on the outer finned surface. The frozen water can be utilized without significant capital expenditure. This direction is, therefore, quite promising as an alternative means of water supply in arid regions of the world. The results of calculation of an atmospheric evaporator designed for gasification of 250 m(3)/h of liquefied natural gas (LNG) with different numbers of external fins (6, 8 or 12) are presented. In 10 h of evaporator operation, a hoarfrost layer of up to an average thickness of 20 mm is formed on the evaporator surface. The specific water volume that can be obtained by regeneration of the evaporator is 1.0-2.7 l/(m(3)/h), depending on the duration of evaporator operation and air humidity. Use of a fan for accelerating heat transfer processes from the air side exerts an effect on reduction of heat transfer surface area, whereupon the frozen water volume also decreases by 15-20%. Estimation of the freshwater volume that can be obtained in the process of utilization of the hoarfrost during gasification of 250 m(3)/h of liquefied natural gas showed that this volume is quite substantial and is enough for meeting daily freshwater needs of several persons. The water needs of several millions of people can be met by utilizing the water obtained by regasification of just 1% of the available LNG (when atmospheric evaporators are used for this purpose).
