Create a hand-drawn Process and Instrumentation Diagram (P&ID) for the following process:

The process begins with calcium carbonate being fed into the calciner, which is heated by an external combustion source. The temperature within the calciner is controlled by temperature sensors and heating elements, with a temperature control system in place to maintain a consistent and stable temperature. The pressure within the calciner is also monitored and controlled by pressure sensors and control valves.

Gas flow is also controlled by flow meters and control valves, with a gas flow control system in place to maintain a consistent flow rate. The particle size of the calcium carbonate is also monitored and controlled by particle size analysis and control valves.

Once the calcination process is complete, the resulting CO2 is cooled down in a shell and tube heat exchanger using water as the coolant. The temperature and pressure of the coolant is monitored and controlled by temperature and pressure sensors, with a temperature and pressure control system in place. The flow rate of the coolant is also monitored and controlled by flow meters and control valves, with a coolant flow control system in place.

Overall, the process is controlled by a series of sensors, control valves, and control systems, with regular monitoring and maintenance of equipment to ensure optimal performance and safety.
