The report gives results of an engineering study and design of methods for scrubbing the exhaust of static-tested solid rockets. Pollutants of major concern were hydrogen chloride and hydrogen fluoride gases. The best process for removing these gases was found to be a gas-atomized spray scrubber, using the power supplied by the rocket to atomize the scrubbing liquid. Four tests in the 22 kN pilot-scale rocket scrubber at the U.S. Air Force Propulsion Laboratory were analyzed to aid in the design. Two types of gas-atomized scrubbers were designed: one was a conventional design similar to a venturi; the other was a low-cost unconventional open type, using neither pressure piping nor a ducted spray chamber. Cost analyses were made for both types of rockets with thrusts between 20 kN and 2 MN.
