Crude benzene equipment

I would like to ask everyone: does the oil circuit of the light benzene oil-depleted cooler tend to get clogged? This post was last edited by ldy6230016 on 2009-3-20 11:29.]
The oil-poor cooler of crude benzene generally does not get clogged, unless the benzene removal efficiency is too low, the oil-poor stream contains high levels of naphthalene, and the cooling temperature is too low, causing the naphthalene dissolved in the washing oil to precipitate and lead to clogging.

Not prone to clogging. Oils that are rich in oil content tend to clog easily. Lean oil, after distillation, has a low content of impurities (such as naphthalene). This post was last edited by ldy6230016 on 2009-3-20 11:29.]
It should not be prone to clogging, whether in the heat exchanger or in the benzene washing tower. The main substance that causes clogging is naphthalene; when the temperature drops below the dew point of naphthalene, it cools and solidifies, adhering to the packing or the inner walls of the heat exchanger, thereby reducing the channel area and lowering the efficiency of heat and mass transfer, which in turn exacerbates the clogging problem. Therefore, temperature control during operation is very important; it is necessary to keep it as constant as possible and minimize fluctuations. As the poster mentioned, there is very little naphthalene in low-oil conditions, so normal operation generally does not lead to clogging problems.
Generally, crude benzene oil-poor coolers are not prone to clogging, unless the oil washing and regeneration process is ineffective, the content of naphthalene is high, and the cooling temperature is low, resulting in the precipitation of naphthalene and subsequent blockage of the heat exchanger.
Oil-poor coolers generally do not get clogged, unless the naphthalene content in the gas is too high, resulting in excessive naphthalene in the washing oil, and the cooling temperature is too low, causing naphthalene to precipitate.
