I would like to ask the experts regarding wax oil hydrogenation units!
Thread Content
Is the temperature rise during the reaction caused by desulfurization and similar processes, or is it due to the high content of light components in the wax oil? How can this be determined? (The analysis of data is delayed; therefore, I would appreciate some guidance – for example, by checking the changes in the parameters of a certain container, it might be possible to determine whether the issue is caused by excessive desulfurization, etc.). Should we focus on the flow rate at low levels or consider other factors? Please give me some advice! This post was last edited by cool99 on 2008-1-7 12:02.]
Olefins, sulfur, and nitrogen can all cause temperature increases; when these increases exceed a certain level, it is usually necessary to introduce cold hydrogen into the bed or increase the circulation rate. The wax oil produced in different plants has varying compositions, and an analysis of the raw materials can help determine what exactly causes the temperature rise during the reaction
Desulfurization, nitrogen removal, and oxygen removal are all exothermic reactions. In addition, demetallization, olefin saturation, and the hydrocracking of certain hydrocarbons are also significant sources of reaction heat. Which type of reaction contributes the most to the exothermic effect depends on the source of the wax oil being processed as well as the operating parameters. The temperature increase is generally between 30 and 60 degrees, depending on the amount of recycled hydrogen; usually, the amount of cold hydrogen used is relatively small
It’s too general. Maybe I didn’t explain it clearly. I mean, if there is a temperature rise in the reactor, or if the temperature rises change. How to determine whether it is caused by changes in sulfur content or by cracking reactions in the reactor. How can one make an intuitive judgment about the device? For example, monitoring the liquid level and flow rate of a certain container
