Control measures for unstable liquid level in the liquefied gas desulfurization tower?
In the past two days, the liquefied gas desulfurization and alcohol extraction tower of the production unit has shown a normal liquid level indication in the extraction tower, but there has been overpressure in the tank ahead of the alkali pump that supplies the extraction tower. Could it be that the tray is clogged? We washed with water for ten hours during the last shutdown. Also, our current liquefied gas flow rate is 2 cubic meters per hour. Is it possible that the low flow rate of liquefied gas prevents the float valve in the tower from opening properly, which in turn stops the alkaline solution from flowing down?
