Tank 41 Salt Dissolution Flowsheet Modeling
A computer simulation model for salt dissolution of Tank 41 was constructed and run for three cases. These case runs show that eight to nine 30,000 gal batches of discharge, 240,000 to 270,000 gal total, are needed to result in the first 100,000 gallons of saltcake transferred out of Tank 41. This equates to 140,000 to 160,000 gallons of inhibited water feed solution after initially refilling the interstitial void. The process plan should allow for 140,000 to 200,000 gallons of batch feed solution in addition to the volume to fill the interstitial void to transfer enough dissolved saltcake to reach the initial 100,000 gal of saltcake goal. The initial fill will vary greatly depending on the extent of interstitial removal and refill. The refill feed volume can range from 23,000 to 230,000 gal. Historical data from Tank 10 salt dissolution was used to compare the results predicted by the model to a real case. The results match the bulk ratios of dissolution water used to salt dissolved and discharge volumes, but consistently under predicted total volumes. This appears to be an artifact of available batch data including flow rates in and out of the tank.
