| 摘 要： | 为了生产安全,甲酸钠连续脱氢生产草酸钠工艺多采用惰性气体(如氮气)作为载热体,工艺复杂,生产成本高。理论计算和对资料的分析表明,用空气作载热体,脱氢反应后的混合气体中氢气的体积分数小于0.04的爆炸下限。只要设计合理,测量、控制、操作得当,用空气作载热体不会出现安全问题,可以有效地简化连续脱氢生产工艺,降低生产成本。

| Abstract: | For safety's reason,we often adopt inert gases(for example N2) as heat carrier in continuous hydrogen removal.It makes the process complex and the costhigh.Theoretical calculating and data analyzing indicates that hydrogen concentration will be below the explosion range of 0.04 while air is heat carrier.Air will be safe as long as design,measure,control and operation are all appropriate.Air as heat carrier will effectively simplify the process and cut down the cost. |
