Component Loss Analysis of HTPB Propellant after High Pressure Waterjet Clearing

摘要

The content of AP and Al in waste propellant and waste water produced by high pressure waterjet clearing HTPB propellant were determined according to some relative standard methods. The results show that the content of AP in the waste propellant with diameter less than 3mm drops from 69.5% to 35.28%, while the loss of Al and adhesives is slight; in the waste propellant with diameter larger than 3mm, the component content is close to normal charge with the increase in radial depth; the content of AP and Al in the waste water are 8368mg/L and 0.157mg/L respectively. Based on above results, the proper treatments of the wastes were chosen: the waste propellant can be used as auxiliary fuel for boilers after leaching AP out with the waste water; the waste water should be treated with biological methods to remove ammonia nitrogen and perchlorate in it.
