13 -- SUPERCRITICAL CARBON DIOXIDE EXTRACTION SYSTEM SOL N00174 POC Brenda Krex, Contract Specialist, 301-743-6570, Penny S. Kennedy, Contracting Officer. The Naval Surface Warfare Center, Indian Head Division (NSWC, IHD) is currently seeking sources and approximate costs for a 25 liter supercritical carbon dioxide extraction system to be used for the development of supercritical carbon dioxide processing of energetic materials. The majority of this work will focus on recrystallization of explosives and coating energetic materials in suercritical carbon dioxide. The maximum working pressure vessels in the system shall be 350bar between -20C and 00C, All ressure vessels in the system must be built to the ASME pressure vessel code. All wetted surfaces of the system must be stainless steel. The extraction vessel must have: an L to D ratio of approximately 3, an automated-full diameter quick opening closure, an agitator, and a basket for collection and removal of micron powders. The vessel at a maximum flow rate of 20 Kg/hr at 350 bar. The system must be capable of recovering the solvent and recycling purified carbon dioxide. The system must be remotely operated (with manual overrides) via a graphical user interface and include a data acquisition system. The control panel must have the capability of being located at least 250 feet from the equipment. Temperaturess and pressures must be monitored and controlled in each process vessel. The rate of each process stream flowing into the extractor must be monitored and controlled. All electrical systmes must comply with the National Electric Code requirements for operations in Class Division grou C and class 2 Division groups E, F, and G hazardous locations. A skid mounted disign is preferable. In addition to the hardware a compllete documentation package including design calculations, P and I diagrams, control logic and equipment specification would be required. Interested sources who can meet the requirments and desire to be considered, need to respond within 30 calendar days, by sending two coppies of descriptive literature containing concept, estimated costs and lead times. Corresponce should be directed to the Supply Department, Indian Head Division, Naval Surface Warfare Center Indian Head MD 20640-5035. This isnot a Request for Proposal. There is no commitment on the part of the U.S. Navy to award a contract as a result of this request for information. (0324)
