Why does blockage of the distillation column trays lead to increased energy consumption of the compressor? Please advise, experts
If the trays in the distillation tower become clogged, the light components cannot evaporate in a timely manner, which results in a lower gas flow rate delivered by the compressor. To prevent surging, the anti-surge valve is opened to increase the circulation volume, and this leads to increased energy consumption.
What was said on the second floor is correct – it’s as if the rich gas is constantly in circulation, which surely increases the energy consumption of the device! ! !
An increase in the pressure drop across the distillation column, along with a decrease in the pressure at the compressor inlet, is probably another factor as well.
The amount of rich gas at the compressor inlet decreases, and in order to reach its normal operating load the compressor must increase its speed, which leads to increased steam consumption.
The trays in the distillation tower are blocked, which results in substandard product; the plant is working uselessly. It’s necessary to determine at which tray level the blockage occurs Only then can we discuss the load issue of the compressor.
When the trays become clogged, the resistance to the flow of oil and gas increases. It is important to ensure that oil and gas can pass through the distillation tower smoothly, which requires maintaining an appropriate pressure difference between the bottom and top of the tower. The best way to reduce the pressure at the top of the tower is to increase the speed of the compressor; as a result, energy consumption will definitely increase
It’s like going up stairs – originally it was running from the third floor to the fifth floor, but now it’s running from the first floor to the fifth floor; obviously more energy will be required:loveliness:
Enabling flight mode is originally a normal operation; it’s merely a control measure used at certain times to protect the crew!
Is it not that the oxygen content isn’t sufficient? If the tray is blocked, as long as the blockage isn’t severe enough to prevent gas from passing through, there should be no difference in the amount of rich gas. It’s just that the pressure drop across the channels increases, which leads to a decrease in the pressure at the inlet of the compressor; if the outlet pressure remains unchanged, the work done by the turbine increases.
The trays in the distillation column are blocked, resulting in an increased pressure drop across the column. With the reaction pressure remaining constant, the pressure at the inlet of the compressor decreases. Meanwhile, the pressure in the absorption tower also remains constant; as a result, the output power of the compressor increases. If there is indeed less gas entering the compressor, it is possible that less work will be done.
