Controls in the Toluene MLR PID (PID-04)
1.  The flow control loop (FIC-10416, FCV-10416) on the feed line is ok.
2.   The control loop (FCV-10459, FIC-10459) on the feed line to the ATFE-1403 has no role to play.  
3.    The level indicator (LI-10417) on the separator (V-1417) is not needed.
4.     Pressure controllers to be used on the steam supply line instead of flow controllers. The pressure controllers will be on the down-streams of the control valve.
5.      Instead of the vacuum control loop (PIC-10477, PSV10477 and PIC-10478, PCV-10478), bleeding inerts will be better.
