13 Optimization for Existing Tilting Pan Filters 13

14 Reliability / Mission Time RELIABILITY speaks of intended function over time. MISSION TIME is critical to maximize acid production 14

15 Filter Mission Times Maintenance turnaround to turnaround Down day to down day (PM the filter) Scheduled wash cycle to wash cycle Scheduled cloth change out to cloth change out 15

16 Wash Cycle to Wash Cycle Mission Times Acid production is critical Interval times are critical 16

17 Cloth Change Mission Times Acid production is critical Intervals - Most Critical 17

18 Filter Performance Optimization This is mechanical approach for existing tilting pan filters, offering increased mechanical reliability and increased recovery of P₂O₅. Results are, a reduction in maintenance costs and increased production dollars. 18

19 Objectives for Filter Optimization Increase acid production Minimize dilution Increase P₂O₅ recovery Lower maintenance costs / Increase mission times Improve cloth cleaning efficiencies 19

20 Filter Optimization Step 1 Initial operational and maintenance benchmarks established. A detailed study and mapping of the filter is completed. 20

21 All aspects of the filter and its parts are measured 21

22 Filter Optimization Step 2 Measured data is integrated into the modeling software. Study of the filter in the “as found” condition begins. 22

23 23

24 Filter Optimization Step 3 The filter is accurately modeled in its optimized condition. Demonstrates the recommended changes 24

25 Filter Optimization Step 4 Client report submittal, steps planned in harmony with client goals Report includes optimized proposal package. (How can Metalcraft best support changes the client would like to see?) 25

26 Filter Software Modeling – Design – Mapping Process 26

27 Components for Optimizing Existing Tilting Pan Filters Cloth spray headers Cam roller turnovers Enlargement of filtration area (pans) Filter valve timing 27

28 Cloth Spray Headers 28

29 Metalcraft Services Nozzle Placement and Spray Patterns are Critical for Cloth Spray Header Efficiencies 29

30 Cloth Spray Header Optimization Nozzle Design and Efficiency Conflicting Sprays Delivered Flow and Pressure to Header Loop Design with Cleanout 30

31 Nozzle Design and Geometry Vee Jet Flat Jet 31

51 Increased Filtration Area 51

52 Increased Filtration Area Considering new pans for an existing filter? Build them with additional filtration area! 52

53 Filtration Area Increased to s/m Filtration Area Increased.46 s/m Per Pan 53

54 Optimization for the Central Valve Is the valve timed correctly? Is dilution being addressed? Are wash and feed boxes located correctly to maximize filter efficiency 54

55 Central Valve 55

56 Optimization of Central Valve Adjustment / Repair of compartment baffles Replace Seal and Wear Plates Machining of Poly Ring and Timing Crown surfaces in place 56
