用临界液萃取技术处理复合固体推进剂的工艺研究

Process Study on Disposal Solid Composite Propellant in Applying Critical Fluid Extraction Technology

通过对火箭发动机含高氯酸铵 (AP)的复合推进剂用临界液氨销毁来介绍这一工艺方法。销毁工艺由四个连续的步骤构成 :第一步采用临界液氨把含 AP的复合推进剂从火箭发动机中取出 ;第二步萃取 AP并将含 AP的液氨和粘结剂残渣分离开 ;第三步从氨水中蒸发出 AP;

Foreign country has been successful in applying critical fluid extraction technology for demilitarization of solid propellant and explosive. This paper introduced the process of critical fluid extraction technology through demilitarization of rocket motors containing ammonium percholrate (AP) composite propellants. The demilitarization process consists of four step. Step one involves removing the AP propellant from the rocket motor. Step two extracts AP and separates the AP/liquid ammonia solution from binder residue. Step three recovers the AP by evaporating the ammonia. Step four condenses the ammonia vapor and recycles the liquid ammonia for a continuous removal/extraction operation.
