May I ask how to introduce oil for starting up the kettle-type reboiler in the stabilizer reboiler, and is the liquid level in the stabilizer determined by the liquid level in the reboiler?
However, there should be no liquid level in the tower during normal operation, as it doesn’t even have a level gauge; the liquid level of the batch reboiler is controlled during normal operation
What device’s stabilizer tower? How is there no level gauge?
Oh. Stabilization towers with kettle-type reboilers have been seen. It’s on one of our old sets. Starting up oil introduction involves establishing a three-tower cycle. In other words, gasoline is taken from the oil storage area and fed into the stabilization system; first, a three-tank cycle is established, and once this cycle is operating properly, crude gasoline obtained through distillation, compressed rich gas, and various operational adjustments are introduced.
The tower of the kettle reboiler does not have a level gauge; the level gauge is located on the reboiler itself.
Starting up oil transfer works just like normal thermal siphoning… If oil is transferred, the reboiler tank in the stabilizer gets filled; otherwise, it’s not possible to fill the heat exchanger tank and establish a three-tank cycle. The gasoline pump also cannot deliver enough flow, and we rely on tower pressure to regulate the output from the unit
Yes, when drawing in oil, the liquid level in the desorption tower reaches 60%, at which point the deethanizer gasoline pump is started to send oil to the stabilizer tower. Once the liquid level in the bottom reboiler of the stabilizer tower reaches 60%, the stabilizer pump can be started to transfer oil to the absorption tower via the absorbent feed line. Once the liquid levels in all three towers are normal, the oil drawing process is completed. Maintain the three-tank cycle: use the desorption tower and stabilization tower as heat sources, draw in crude gasoline; the excess gasoline is sent out under the pressure generated by the towers themselves. Draw in compressed rich gas and adjust the operations accordingly……
