E -- FABRICATION AND INSTALLATION OF AN EMISSION CONTROL SYSTEM SOL DAAD05-95-R-0885 DUE 081595 POC Contract Specialist John M. Robb (410) 278-2024 (Site Code DAAD05) The U.S. Army Aberdeen Test Center (ATC) has a requirement for fabrication and installation of an Emission Control System (ECS) as part of the Fire Safety Test Enclosure (FSTE) at Aberdeen Proving Ground, MD. The air filtration path shall have approximately a 32,000 CFM capability and shall interface with the containment vessel to be assembled under a separate contract. The ECS shall be a dual train system, with each train having at approximately 16,000 CFM capacity. The first train shall be procured as part of this effort with the option for a second train at a later date. The feed air to the ECS shall be monitored to determine concentrations of gaseous effluent in order to control process parameters. The ECS shall be designed to handle all the test effluent released from test items during the following test scenarios: (a) A high-explosive blast equivalent to 100 lb TNT detonated in the center of the containment vessel within + or -2 ft and approximately 12 ft from the center of the floor surface. (b) Test Scenario (a) combined with the burning of 650 lbs of JA-2 propellant. (c) Test Scenario (a) combined with the burning of a maximum of 250 lbs of diesel fuel and 500 lbs of JA-2 proponent. Maximum Halon 1301 discharge is 1,000 lbs. (d) Test with a high explosive blast no greater than the equivalent of 10 lbs TNT. (e) Test Scenario (d) combined with the burning of a maximum of 500 gallons. (f) Test scenario (d) combined with the burning of a maximum 250 gallons of diesel fuel and 500 lbs of JA-2 propellant. The ECS shall interface with and shall handle gaseous effluent coming from the top of the containment vessel and treat them before release. These effluent include the following types of materials and their combustion by products; propellants, explosives, hydrocarbons, Halons, NOX, VOCs, CO, particulates, metals, and other materials typically found in flammability and fire suppression testing. The effluent shall be treated by an thermal oxidizer (secondary combustion chamber), evaporative quench tower, spay dryer absorber and a filter bag house. The ECS equipment shall meet or exceed all federal, state, and local environmental regulations for processing equipment. The anticipated emissions at the end of ECS exhaust train are water vapor and CO2. There shall be provisions to remove solid products form the ECS. All facility control instrumentation and electrical requirements shall be part of this procurement. The ECS shall differ from other standard industrial emission control devices by having the capability to ramp up and/or down to provide for an efficient batch process during approximately four test scenarios per day. The contractor who is awarded the contract shall have expertise in design, fabrication, and assemble of systems of this nature. The contractor shall be responsible for providing a completely operational system with variable controls. All responsible sources may submit an offer which shall be considered by this agency. No telephone requests, only written or facsimile requests (410-278-7447) will be honored. (0181)
