| 摘 要： | 在无萃取情况下研究了甲醇－－石油醚体系安全操作范围,发现出现液泛时的持液量为30％,确定了安全操作曲线,认为安全操作的持液量为24％;然后以棉仁为处理对象,依据安全操作曲线选择三组操作参数进行实际萃取,验证了操作曲线的可靠性并发现持液量对萃取效率影响的关系曲线。

| Abstract: | The paper studied on safe operation curve of the column and relation between hold up and extraction efficiency.Results of experiment showed:1.Under without actual extraction,hold up value of flooding of column was about 30%,so 24% was proposed best value for actual operation and safe operation curve was obtained.2.Experiment whose parameters were chosen according to the curve proved that hold up value (24%)and the curve were efficient.3.The curve between hold up and extraction efficiency was the horizontal reverse form of "S"(Fig.10) |
