I’d like to ask the experts: what is a dividing line? ?
Thread Content
Can’t find the management divider for the process section currently? ? Forum moderators also need to strengthen management~ What does the separator in this sentence mean? @Fish in the desert
It’s that post about improving panel management
Don’t you upgrade the management level after reading each post?
At the end of page four, we’re almost at page five. There are indeed many unmanaged posts in the Process section. HaiChuanWoker’s large-scale “public welfare” campaign has blossomed beautifully! Process version – After management, please move it up to: http://bbs.hcbbs.com/thread-1316393-1-1.html (Source: Haichuan Chemical Forum). The purpose of the management separator is to move it up after management; unmanaged posts are also moved up together, so as to indicate the management location and facilitate further management by the next person in charge
The divider indicates that all posts below it are managed by the moderators, for the convenience of other moderators. Can’t find the separator? 1. Check the person in charge of the corresponding region; in the topic posted by @*lihuagong, you can find the relevant post. Click on it and proceed with the promotion. However, make sure that all posts in this section have been read. 2. Management Records -> Moderator Management Records -> Separator -> Search.
It was explained in great detail upstairs; the separator corresponds to my post. For specific management methods, you can refer to this training post: [Moderator Training] Session 7: Comprehensive Management – Managing Separators http://bbs.hcbbs.com/thread-1359449-1-1.html (Source: Haichuan Chemical Forum)
Thank you~~:handshake
The full English name of TBP is True Boiling Point, which means the actual boiling point. The specifications requested by the customer specify that the cutting point between heavy naphtha and kerosene at the true boiling point is 155°C. The true boiling point curve shows the temperature values at different distillation percentages such as 100%, 95%, etc. By using these temperature values along with the corresponding distillation percentages, it is possible to create a true boiling point distillation curve. From this curve, the distillation percentage at 155°C can be determined, thereby allowing the calculation of the yields of heavy naphtha, kerosene, and so on
Since crude oil is a mixture rather than a pure substance, it does not have a single boiling point like pure substances. When oil is heated to different temperatures, mixtures with varying compositions are distilled out; moreover, different distillation conditions result in mixtures with different compositions being distilled at the same temperature range. Depending on these conditions, different names are given to such mixtures. The TBP you mentioned is an abbreviation for true boiling point, which refers to the actual boiling point of the substance. The cutting range you mentioned refers to the temperature range of each cutting fraction in true boiling point distillation. It should have resolved your doubts
Young man, did you send it to the wrong place? ;P
