Comments on Toluene MLR PID (PID-04)
1.   There will be a liquid seal loop on the feed line connecting the separator (V-1417) and ATFE-1403. The height of this loop will be equivalent to the difference in the operating pressures of the RFE and the ATFE systems    
2.   There will be a flash separator on the feed line of the ATFE-1403    
3.   The overflow tapping (feed line from the separator (V-1417) to the ATFE-1403) should be as close to the separator (V-1417) bottom nozzle as possible.
