微波干燥法用于石油产品中机械杂质的测定

Determinatiom of suspend mechanical impurity in petroleum product by microwave drying

采用了微波干燥法测定石油产品中的机械杂质 ,确定了较佳的微波干燥条件 :滤纸与称量瓶的恒重 ,在功率 5 4 0W时 ,恒重时间 3min ;机械杂质在 0 .5g左右 ,功率 5 4 0W时 ,恒重时间只需 7min ;机械杂质在 0 .1g左右 ,功率 5 4 0W ,恒重时间则只需 5min。和传统的方法相比 ,本法具有快速、准确度高、操作方便、节约能耗、提高工作效率等优点 ,可用于各种石油产品中机械杂质测定 ,也可推广应用于其它重量分析法。

Adopted the dry method of microwaved heat to measurement the mechanical impurity of petroleum product, and determine the dry term of good microwave,When The mechanical impurity is 0.5 g, power is 540 W, the time of equal heavy is 7 minutes, The mechanical impurity is 0.1 g, power is 540 W, the time of equal heavy is 5 minutes. With the tradition of the method compare, and this method have fleetness, the accurate degree is high, operation convenient, the economy in electricity advantage, It can be used to measurement the mechanical impurity of petroleum product also can be expand application in the other weight to analyze the method.
