Research On The Transformation Path Of Heavy Metals In The Process Of Crude Oil Processing In A Refinery

With the growing shortage of crude oil resources in China,the use of inferior crude oil is more and more extensive,the heavy metal content contained in crude oil also increases with the increase of inferior oil,Therefore,the refinery heavy metal pollution problem has gradually attracted people's attention.In this paper,a refinery in North China as the research object,mainly for the refinery of solid emissions research,selected V,Cr,Mn,Fe,Co,Ni,Cu,Zn,As,Cd,Pb this 11 typical heavy metal elements are used as characteristic contaminants to carry out the source analysis of these heavy metal elements in the waste of the refinery.At the same time,through the study of the pollution characteristics of heavy metals in the solid waste from the refinery,the types,contents and contributions of the heavy metals in the refinery waste can be obtained,and the presence or absence of characteristic pollutants can be determined.In addition,according to the refinery process and the concentration of heavy metals into and out of the material to determine the source of heavy metal pollution in solid waste,and then we can determine the discharge capacity of each device to develop a corresponding pollution control plan.After the determination and analysis of the heavy metal content in the waste of the refinery,we can understand that the heavy metal content of the solid waste produced by the refinery is high.There is a concentration of up to 400000?g / g or more,and the content is close to 0,for these containing a lot of heavy metal solid waste if there is no efficient treatment method,will be on the one hand the environment caused great harm,on the other hand will also cause Heavy waste of heavy metal resources.we can also according to the data and analysis of heavy metal source analysis of the study,we understand that different elements are mainly derived from what kind of devices,to develop a corresponding plan,From the source to reduce heavy metal emissions.After this study,we know that heavy metal emissions from solid waste in refineries and the list of heavy metal pollution emissions from various installations,the majorpollutants and their sources of different devices,and the major sources of heavy metals and heavy metals in these refineries Process of migration process.
