Reformation liquid-phase dechlorination tank
Thread Content
What are the differences and advantages/disadvantages between top-in-bottom-out and bottom-in-top-out configurations for the liquid dechlorination tank in the reformation process? I hope the experts here can give some guidance!
I have also considered this issue and consulted the professionals here; their answer was that if gas is introduced from above, gas will accumulate in the bed layer. Since it is liquid-phase hydrogenation, this affects the efficiency of the reaction. Additionally, the accumulation of gas in the bed layer increases the pressure drop, which in turn affects the processing capacity of each reactor (we have four tubular reactors arranged side by side). This problem does not occur when gas is introduced from below. I hope this helps!
But why do the gasoline dechlorination tanks in our equipment all have fluid flow from top to bottom? I’ve seen several reprocessing facilities, and it seems they’re all arranged in this way!
Here, flow also occurs normally from bottom to top. The initial design proposed by the design team was for flow from bottom to top, but after consulting with the chlorination agent manufacturers and the manufacturers of chlorination tanks, it was changed to flow from top to bottom. I’m not really sure what the specific differences are
It is recommended that the liquid-phase dechlorination tank have liquid inlet at the top and outlet at the bottom; the design with liquid inlet at the bottom and outlet at the top is less effective in resisting interference, as an emergency shutdown of the system can easily cause disturbances in the dechlorinating agent.
