How to determine the slag discharge time and amount for the benzene system regenerator?

2 to 3 times a week, when draining the slag. It is best to refuel at night and discharge waste during the day.

The timing and amount of slag discharge from the regenerator are determined based on the quality of the circulating wash oil, while the timing and quantity of new wash oil to be added are determined based on the liquid levels in the rich and poor oil tanks

How to determine the slag discharge time and amount for the benzene system regenerator? Answer: The oil feed rate to the regenerator is adjusted based on the temperature of the regenerator, as well as the bottom temperature of the benzene removal tower; adjustments can be made using these two operational parameters. The timing for slag discharge is determined entirely by the temperature of the regenerator – slag discharge can take place when the temperature reaches around 190–200 degrees Celsius. There is no fixed amount for the slag to be removed; it depends on the quality of the oil. If the quality is poor and the oil is too thick, more slag will be produced during the regeneration process. Each time slag is discharged, it must be completely removed; just vent the steam. How to determine the timing and amount of adding new washing oil? Answer: There are many factors that affect this, such as the oil circulation rate of the system, the liquid levels in various circulation tanks, the volume of gas flow, the operating temperature of the benzene washing tower, as well as the amount of impurities in the gas – in other words, the quality of the gas, and so on. During the operation process, it is most important to maintain stability in the operational parameters as well as the liquid level in the circulation tank. The temperature for benzene washing must be controlled properly; otherwise, a large amount of the washing oil will be carried away by the gas. The timing and amount of the washing oil added are not fixed; its addition must ensure that the system operates stably and normally. While striving for meticulous management, it is also necessary to abide by objective laws.

The explanation upstairs is quite comprehensive; however, keeping the slag discharge temperature at 190–200 seems a bit low, doesn’t it? When using superheated steam for heating, the temperature at the bottom of the regenerator should also reach around 260 degrees; otherwise, it’s only possible to discharge wet slag.

Excuse me, for the 2nd floor, how do you take photos during the day? Aren’t you afraid of the environmental protection agency? :Lol, it’s still better at night, the lighting is better, and be safe:(
