摘　　要：通过对前人实验研究成果归纳,阐述了影响储罐内压力及蒸发率的主要因素,分析了加强绝热保冷及消除分层的意义,介绍了国内外蒸发气(简称BOG)产生及控制的开发与研究进展,指出了实际生产中BOG产生量较多,强调了BOG"产生控制,排出控制"的合理性,并提出了合理提高设备使用率,实现对其技术与经济两方面优化的必要性。Based on the previous research results,the main factors influencing the pressure and evaporation rate in the tank are expounded,and the significance of strengthening the thermal insulation and eliminating the stratification is analyzed.Utilization situations of boil-off gas(BOG)produce and control at home and abroad were reviewed.It points out that BOG production in actual production is more,and emphasizes the rationality of BOG"generating control and discharge control".It puts forward the necessity of rationally improving the use rate of equipment and realizing its technical and economic optimization.

关 键 词：分层 蒸发率 绝热保冷 使用率 优化
