Please Hand$-$draw the following: Develop the piping and instrumentation diagram $($P&ID$)$ of a separator which has mixture of gas, oil and water it through an inlet header $(4$ inch sch $40$CS $)$ and leaving it through outlet gas header $(2$ in Sch $80),$ oil and water streams located at the bottom of the separator $4$ inch Sch $40$ each. The diagram should show:

i$.$ A flow control loop on the inlet stream.

ii$.$ A pressure control loop and safety measures on outlet gas header.

iii. A level control loop and isolation, maintenance and monitoring measures for oil and water levels.

Inlet: gas, oil and water
