The third will be attached to the east end of the main building. This <br />building will house the CO2 liquidizing equipment. Additional lean-to <br />the main building will house fire water pumps, pipe line Eeed pumps, <br />miscellaneous process pumps and compressors. The main building will <br />be comprised of two sections. The first will be 75 ft. wide, 210 ft. long and <br />100 ft high and will house the filters and main process units. The other <br />section will be 75 ft wide, 120 ft long and 36 ft high and will house the <br />heat exchangers. The pre-engineered building that will house the <br />administration will be 50 ft wide, 100 ft long and 16 ft high. The boilers <br />building will be 75 ft. wide, 140 ft. long and 36 ft high. The COZ building <br />will be 50 ft wide, 75 ft long and 36 ft high. The buildings will be provided <br />with thermal insulation and roof mounted mechanical ventilators with <br />corresponding set of wall louvers at the lower wall elevation. <br />5.1.2 SOLUTION MINING AND WELLHEAD (AREA 11) <br />A well injection pumping system of four pumps operating and one <br />standby will be installed in the process plant. These pumps will take <br />preheated spent brine and will pump it through two heat exchangers <br />connected in parallel. The spent brine at approximately 425° F and 600 <br />psig then will be injected into the wells. The plant capacity will require 26 <br />production wells operating at the same time. <br />Each wellhead will be provided with a gas separator to release any <br />methane gas carry over from the well by the solution. The mine facilities <br />will include the installation of a brine surge horizontal tank 17' dia by 30' <br />long installed near the wells. The solution from all the operating wells <br />will be collected in this tank before it is pumped to the process plant. A <br />pumping station comprised of five horizontal centrifugal pumps, <br />including one stand-by, will transfer 3000 gpm of mine solution at a <br />temperature of 300 °F from the brine solution tank to the 1st stage steam <br />stripper located in the process building. <br />5.2 LOWER PLANT <br />5.2.1 GENERAL (AREA 02) <br />The lower plant will be built on the former Unocal property. Some <br />existing buildings will be used for warehouse, maintenance shop, locker <br />rooms, laboratory, firehouse, clinic, guard house, administration offices, <br />fire water pump building, boiler water treatment, cooling tower, reagent <br />building and the control building. All these buildings will be refurbished <br />and modified to conform with the needs of the new American Soda <br />operation. The existing refinery and process buildings located at the west <br />43 <br />
