Fluidized Bed Rubber Denuding System Maintenance

Red River Army Depot (RRAD), Texarkana, Texas, has a requirement for maintenance and repair of the Fluidized Bed Rubber Denuding System (FBRDS). All maintenance and repair work is associated with requirements stated in the Air Emissions Operating Permit issued to Red River Army Depot by the Texas Commission on Environmental Quality. The FBRDS consists of two independent fluidization beds, two quench tanks, two pollution abatement systems, a common control room, and associated ancillary equipment. Interested parties should be able to efficiently perform the maintenance and repair work that includes but is not limited to:

a. Level IV Maintenance.  Annual maintenance performed by factory trained personnel as required by the FBRDS maintenance schedule requirement of the TCEQ permit.

b.   Level III Maintenance.  Semiannual maintenances performed yearly by factory trained personnel as required by the FBRDS maintenance schedule requirement of the TCEQ permit.

c.   Air Quench and Water Quench Replacement/Repair.  Replacement of major wear items of the cooling tower which include main inner cooling tube, U-tube and the installation of exterior insulation. Cooling tower water must be properly disposed of, not discharged to the ground.  Water quench tank replacement of major wear items including conveyor chain and major shafts and hubs.  Repairs will occur during Level IV Maintenance.

d. Fluidized Bed Sand.  Replacement of fluidizing sand as needed through general usage and total yearly replacement during yearly maintenance.  It is the specific material properties of the sand; material composition and particle size distributions that contribute to the Fluidization action during the denuding process.  Efficient operation of the FBRDS is directly related to the characteristics of the sand.

e. Gas Stream Lime Additive.  The Lime controls the sorption of Sulphur oxides (SO2) in the flue gas stream.  Regulation of SO2 during the denuding operation is a requirement of the RRAD, Texas Commission on Environmental Quality (TCEQ) Air Permit.  The material properties of the Lime; particle size, specific area, moisture content, affect the dosing equipment and sorption efficiency which directly control the amount of SO2 in the flue stream.

f. Yearly Spare Parts Replacement.  Spare parts necessary to support operation of the Fluidized Bed will be supplied on request to prevent shutdown.  These parts are known to have to be replaced on a routine basis for continual operation.

g.   Emergency System Repair.  This 24 hour response to repair equipment failures or shutdowns is to prevent unforeseen production stoppages.

h. Non Pre-Priced Parts.  These are major parts that are nearing their rated life that will have to be replaced during this contract period.
