LNG dehydrogenation tower
Thread Content
When the operating load is high, what causes the reflux tank to fail to reflux, and how can this be resolved? ? ?
Check whether the vapor equilibrium tube is unobstructed.
The reflux tank is equipped with a U-tube for reflux; as the vapor from the dehydrogenation tower condenses and enters the reflux tank, the resulting liquid level causes the fluid to flow back to the dehydrogenation tower due to the difference in liquid levels. Check whether the valve in the return pipeline is blocked and whether there is insufficient cooling capacity in the dehydrogenation tower condenser
