Petroleum flashing in the flash tank
Thread Content
Under the same parameters, naphtha is distilled off at the top of the flash tank from heavy crude oil, but not from light crude oil. Why is this?
The composition of crude oils varies! The hydrocarbon content is different!
Given the differences in crude oil properties, it is best to have a comprehensive analysis conducted
The crude oil becomes lighter, and the temperature drops after the replacement. Check the feed temperature of your flash tower
I guess the parameter you’re referring to is the feed temperature. However, the flash pressure of light crude oil is higher, which can affect the flashing process; but it shouldn’t prevent the production of naphtha. The backpressure in the system where the vapor is flashed must be too high! ! ! ,
