Show ESTIMATE OF TODAY'S COSTS FOR A LIKE APPLICATION AI A 290000 #/UB COAL FIRED CFB The estimated cost of a THERMAL DENOx system of this type applied to a~ 290000 lb/hr Coal Fired CFB boiler in a California location at today's third Quarter 1992 costs is estimated below: • Equipment, K$ • Field Labor, K$ • Indirect Costs. KS Iotal Erected Cost, K$ 240 90 3.W 640 The Equipment Cost estimate includes the compressor, tankage, vaporizer, one zone and nozzles, valves, piping, and instrumentation (excluding the NOx/NH3 Continuous Emissions Monitors) as described earlier. The estimate includes cost of all material and shop fabricated items. The Indirect Costs include field labor overheads, erection fees, contractors engineering and fees, and ER&E process design engineering costs. All three categories include a 15 % Contingency. Excluded are special site specific items such as pilings, roads, etc, and the license fee. The cost effectiveness and NOx reduction can also be estimated as: 7 year T.E.C. Payout (1) NH3 Cost (2) Power Cost( 3 ) MaintenancelLabor (4) TOTAL 91 K$/yr 70 K$/yr 44 K$/yr 16 KS/yr 221 K$/yr NOx Reduced = 956049 Ib/yr Or, expressed as $/ton of NOx removed, the costs can be e·xpressed as: 221.000 S/yr = 0.231 S/lb NOx 956049 Lb/yr removed = 462 $/ION NOx removed These figures should be read with caution. Application of the THERMAL DENOx process is unit specific and, therefore, must be designed and estimated for each piece of fired equipment. Therefore, the costs provided herein are applicable only to a system applied to a coal fired CFB like that at Jasmin. Please note that Exxon Research and Engineering Company does not provide detailed engineering services nor do we procure or supply any hardware for THERMAL DENOx systems. These functions are best provided by yourselves, your subcontractor, or a subcontractor experienced in THERMAL DENOx systems. The costs provided above are for the purpose of showing the current cost estimate for a system similar to that at the Jasmin plant.
