28 Replacing T pieces & Ball valves with Diverters Dead space area The clean alternative o Diverter valves seal at the take-off point, eliminating dead space o Continuous back flushing is not required. o Design more compact T-piece o Very advantageous, especially when 3 or more parallel outlets are required. Standby Valve Closed Ball Valve 2 Open The old solution Normally T pieces and ball or plug valves are used to isolate the standby valve, resulting in dead space from the takeoff point If the liquid is a solid containing slurry, the solids can settle in the ball valve and in the pipe. One solution is the use back flushing, i.e. to continuously flush the dead lag back into the main line. However this adds cost and can considerably reduce plant throughput. Slide 27

31 Pump Switching Diverter Valves 2-6 Way Feed Pump Diverter Valve o In many plants several pumps are used in parallel. Of these one is always in standby allowing for repair or maintenance without affecting plant performance. o Normally T pieces and ball or plug valves are used to isolate the standby valve, resulting in dead space from the takeoff point to the isolation valve. Diverter valves eliminate this dead space o Flushing / Cleaning / Draining valves can be included in the body of the diverter to optimise cleaning Slide 30
