The pressure in the atmospheric tower is high; please take a look

How to determine whether the reflux in the tower is appropriate or not
I can’t see your image; figuring out the source of the gas phase will resolve it. There is a blockage in the vapor line at the top of the tower, preventing proper flow. The vapor has not condensed; increase air cooling or water cooling.
What is the typical pressure exerted on atmospheric pressure towers?
It depends on what the design pressure is; it varies from one refinery to another
1. Increase the flow rate of the cooling water at the top of the tower. 2. Reduce the heat bypass at the top of the tower. 3
1. Increase the circulating water flow in the tower top cooler. 2. Reduce the heat bypass at the tower top. 3. Open the shell-side vent of the tower top cooler
First, the tower steam volume and reflux should not be too high. Second, open the valves for the circulating water or other cooling medium in the tower top condenser and the aftercooler. Third, check the opening degree of the atmospheric tower vent valve. Fourth, check whether the vent pipe has a low point to prevent condensation from forming in the pipe and creating a liquid seal
