在实际计量工作中经常遇到油品分层现象,尤其是冬季温差较大的时候,原因如下。1.裸罐是造成温度分层的主要原因。2.由于加工工艺或目的产品要求的不同,在同一油罐中存在密度或温度分层的现象。如作为燃料油的汽油、柴油等产品,经过多道工序调和基本上混合相对均匀;而作为基础原料的半成品,如石脑油、铝箔基础油在油罐中就不需要调和。其混合程度相对较差,
In the actual measurement of oil often encounter stratification, especially when the temperature difference is large in winter, the following reasons. 1 bare cans is the main reason for temperature stratification. 2. Due to the differences in processing technology or product requirements, density or temperature stratification occurs in the same tank. For example, gasoline, diesel oil and other products as fuel oil are basically evenly mixed through multiple processes and the semi-finished products such as naphtha and aluminum foil base oil, which are the basic raw materials, do not need to be reconciled in the oil tank. The degree of mixing is relatively poor,
