Task 1 calls for the design, procurement, construction, and installation of the Seed Regeneration Proof-of-Concept Facility (SRPF) (Figure 1) that will produce tonnage quantities of recyclable potassium formate seed at a design rate of 250 lb/hr for testing in the channel at the CDIF while collecting data that will be used to upgrade the design of a 300 MW{sub t} system. Approximately 12 tons of KCOOH (dry basis) as 70--75 wt% solution have been produced. The front end of the plant (potassium sulfate reaction and solids separation/washing units) was operated for five days in March. Most of the operations were conducted at a spent seed feed rate of 250 pounds/hour. A total of {approximately}8,500 gallons of dilute KCOOH solution was generated containing approximately 2.6 tons of potassium formate (dry basis). The average KCOOH content of this solution was -7 wt%. The design KCOOH solution concentration for the front end of the plant is 8.5 wt%. The evaporation unit was operated or a total six days during March. Approximately 2.5 tons of potassium formate (dry basis) were processed through the evaporator and concentrated to >70 wt%.
