How to improve the yield of wax oil under normal and vacuum pressure?
Thread Content
How to increase the yield of atmospheric and vacuum wax oil while keeping the crude oil unchanged? How should this be done? Change those operating parameters? Such as temperature, pressure, etc. Thanks!
To improve the yield of wax oil, the main operations are to increase the vacuum degree of the vacuum tower and increase the outlet temperature of the vacuum furnace. If you design a new device, you need to consider more aspects.
Increase the vacuum degree of the decompression tower, but if you increase it only so much, if it is too high, you are afraid of an accident. The furnace temperature cannot be raised. Generally, the feed temperature of the vacuum furnace is only about 380. If it is too high, it will easily cause the heavy oil to crack, affect the operation, and actually reduce the yield. In fact, there is no good way to improve the yield of wax oil. The properties of the oil determine its content, and the first step is to increase the yield of light oil. A high yield of wax oil means pulling out more lateral lines, and ensuring that the product is qualified.……
Improve fractionation accuracy and reduce operating pressure.
Thanks! But is there an upper limit to increasing the outlet temperature of the decompression furnace? You can't just improve it casually, right? If I want to do a simulation, I can increase it as much as I want, but I don’t know what the actual upper limit is?
Can you be more specific? Improve fractionation accuracy there? Fractionating tower? Atmospheric pressure tower? Pressure reduction tower? Reduce operating pressure there? Thank you very much!
