- Description
- This is a combined synopsis/solicitation for commercial items. This announcement constitutes the only solicitation. Proposals are being requested and a written solicitation will not be issued. RFP #DAAE30-02-R-0825. The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular (01-07). The US Army ARDEC, Picatinny Arsenal has the following requirement: Scope/Program Objective: The contractor shall provide a solvent vapor recovery system for mixers. The explosion proof vapor recovery unit will be use for the removal of solvents contaminated with energetic materials as a result of processing Nitrocellulose based gun propellants. The vapor recovery unit shall be able to handle a variety of solvents in air with normal humidity levels. The solvents shall include in this design Ethyl Acetate, Ethanol, Acetone, and Diethyl Ether. As part of the U.S. Army?s research and development activities, Picatinny Arsenal operates three batch mixers used for the small-scale production of propellants. Dry and liquid (solvent) components are combined in the mixers. The liquid portion is stripped until an extrudable product remains. Solvents are stripped by passing an air stream over the propellant mix. The effluent air stream (air/solvents) from the mixer will pass through a condenser and the solvents will be condensed and collected for disposal by using the vapor recovery unit. Full-scale operation of the mixers in Building 1408 results in solvent vapor effluents in excess of New Jersey limits. The proposed system should capture the vapor effluents and put the mixers in compliance with the New Jersey effluent limits. PERFORMANCE REQUIREMENTS: The system shall be capable of condensing solvent vapors from a solvent vapor/nitrogen stream by chilling the vapors in a condenser with a cold refrigerant medium. Compression of the vapors will not be allowed because of the inherent hazards associated with compression of the explosive mixture. The system shall be equipped with a Class I, Groups C and D, Division I, explosion proof exhaust fan capable of moving 15 SCFM of purging nitrogen plus each of the following solvent effluents a distance of 61 feet from the source to the condenser. The solvents to be condensed vary from a heavy concentration early in the 30 minute cycle to a light concentration later in the 30 minute cycle. Additional information on the vapor emission are shown below. The three solvent vapor streams individually are as follows: Diethyl ether/ethanol solvent vapor effluent from mixer 96.5% recovery required ELAPSED TIME(Minutes) 0-10 10-20 20-30 Total at 30n minutes ETHER( LBS) 19.90 13.26 6.63 39.79 ETHANOL 10.68 7.12 3.56 21.36 TOTAL 30.58 20.38 10.19 61.15 Ethyl/Ethanol Solvent Vapor Effluent from Mixer 96.5% recovery required ELAPSED TIME (Minute) 0-10 10-20 20-30 Total at 30 minutes Ether (lbs) 12 8 4 24 Ethanol 3 2 1 6 Total 15 10 5 30 Acetone/Ethanol solvent vapor effluent from mixer 96.5% recovery required ELAPSED TIME(Minutes) 0-10 10-20 20-30 Total at 30 minutes ACETONE (LBS) 7.56 5.03 2.25 15.11 Ethanol(LBS) 11.34 7.57 3.78 22.69 TOTAL 18.90 12.60 6.30 37.80 The vapor recovery system shall be capable of cooling the vapor streams to ?50 degrees Fahrenheit and must recover 96.5% of the solvent vapors. The vapor condenser shall be capable of collecting all of the condensed liquid. The discharge of the condenser shall be at least 16 inches above the base of the system to allow for drainage by gravity into a container. The heat exchanger must be designed to prevent reduction in optimum system condensing capacity resulting from vapor flow reductions caused by frost accumulations. The vapor recovery system is to be electrically operated. All electrical system shall meet Class I, Group D, Division I, environmental requirements. The vapor recovery system shall be completely packaged and skid mounted. It shall be designed for location outdoors, must be air cooled, and automatically operated. The system shall be mounted in a walk-in weatherproof enclosure. All controls are to be located within enclosure. The following system interface connections are to be supplied: flanged vapor inlet and outlet, single point power connections, common fault alarm dry contacts and red light to signal unplanned system shutdowns, condensate drain valve connection, vapor condenser outlet temperature dry contacts and red light to signal temperature rise on vapor discharge. The explosion proof exhaust fan to pull vapors from the source shall be located on the condenser. The exhaust fan blades must be of a non-ferrous metal. The system shall be capable of operating from the 460 volts, 3 phase, 60-hertz and 115 volts, 1 phase 60n hertz power sources available. The package system shall not exceed a dimensional envelope of 14 feet long x 7 feet wide x 10 feet high. Contractor shall prepare and submit engineering drawings. Three copies of an operating and maintenance commercial manual. Specifications on duct or pipe required to convey vapors from the 50- gallon mixer to condenser. Contractor shall submit engineering drawings and installation. The contractor shall warrant the system for defects in workmanship and materials for one year from the date of start-up. Two days of start-up and training service shall be provided after ARDEC installs the equipment. Installation will be accomplished not more than one year after delivery to ARDEC. The quoted price shall include shipment to ARDEC. ARDEC will provide the required mounting slab, will unload the unit and place it on the mounting slab, will provide all the required electrical utilities and will install all required vapor ducts. If interested in submitting a proposal, please contact for special requirements. EVALUATION CRITERIA: Lowest price technically acceptable. Proposals are due by 1600 hours, August 1, 2002 and can be sent by facsimile, electronic mail or mailed to US Army TACOM/ARDEC, AMSTA-AQ-APH, Bldg. 9, Attn: Kathy Hansen, Picatinny Arsenal, NJ 07806-5000.
