Design a p&id of a liquid liquid extraction column with control measures in autocad

Use the information:

Column is being used to separate phosphorous acid (desired) from phosphorous acid, using countercurrent extraction and butanol as a solvent

Level control: The level of the liquid in the column should be continuously monitored and controlled to maintain a constant level. The liquid level can be controlled using level sensors and a control valve that adjusts the flow rate of the feed stream.

Temperature control: The temperature in the column should be closely monitored and controlled to ensure that the process operates within the desired range. The temperature control can be achieved through the use of thermocouples, which measure the temperature and send signals to a control system that adjusts the heat input.

Pressure control: The pressure in the column should be maintained within a specified range to ensure safe operation. Pressure control can be achieved using pressure sensors and a control valve that adjusts the flow rate of the gas stream.

Flow control: The flow rate of the feed and solvent streams should be closely monitored and controlled to maintain the desired flow rate. Flow control can be achieved through the use of flow meters and control valves that adjust the flow rate of the streams.

Emergency shutdown: In the event of an emergency, an automatic shutdown system should be installed to stop the operation of the column and prevent any hazardous incidents. The emergency shutdown system can be triggered by various sensors that detect abnormal conditions such as high pressure or temperature.
