Shakeri DATE: October 5,1992 Subject: Justification For WEL-2 Clean-Up Project Job # 7065 Title Current justification for Line 3 WEL-2 clean-up project Oriqinal Justification Solubles Savings (353,024 lbs tobacco/yr) $ 29,745/yr Fiber Savings ( 34,672 lbs tobacco/yr) $ 2,921/yr Fresh Water Savings $ 788/yr Waste Water Savings $ 4,465/yr ----------------------------------------------------------- Total Savings $ 37,919/yr The original estimated savings allowed this project to have an ROI of 19.2%. Current Situation Since excess liquor shedding has been documented from Jan,1991, Line 3 Stock Prep has shed liquor 15 out of 18 months, as CEL and/or SEL. After removal of Hycor rotoshear from Line 3 Blending on 01/08/92, liquor shedding has significantly decreased;however this coincides with blend change on 01/13/92. (see figure 1) Other Considerations Future liquor shedding can not be quantified due to: * Impact of low humectant RL on solubles usage * Feed stock solubles (blend change) * Finished sheet solubles target * Press efficiency

Current Justification Philip 0nfid~~fial Fiber Savings (34,672 lbs of tobacco/yr) $ 2,A14fr1Wy A8C Fresh Water Savings $ 788/yr Total Savings $ 3,709/yr These savings will allow this project to have an ROI of approximately 2%. ( This figure does not include operational cost of the rotoshear) Conclusion Based upon current information on excess liquor shedding, the original project ROI has dropped form 19.2% to 2% Current justification does not meet requirements to implement the WEL-2 clean-up project. Recommendation * Discontinue expenditures on this capital project * Proceed with recommended Hycor modifications : . Relocate the internal shower spray bar so it can safely be removed from:the influent end of the unit. . To increase throughput, replace existing flights with continuous flights. Modify the headbox design by lengthening the headbox. . For cleaning purposes, install access door in the headbox to eliminate dead spots. These modifications will be done free of charge by Hycor. c: * Place Hycor in spare equipment inventory to be used for a future alternative clean-up application * Close-out capital project and appropriate monies to plant operating expense D.A.
