Ammonium perchlorate dust extraction plant
Our dust extraction systems in the aerospace industry
To support a client company operating in the aerospace industry, Coral, which specializes in the design of extraction and filtration systems, provided a special dust extraction system to reduce ammonium perchlorate emissions and support it during drum emptying and filling operations. The powerful oxidizer is extremely functional in advanced mechanics, as it makes up three-quarters of the space propellant used in rocket engines.
How the system for ammonium perchlorate management works
Thedust suction equipment used consists of a suction arm of appropriate length, positioned to the rear of the affected area. During the emptying stages, it is used to vacuum dust directly at the production source, without getting in the way of the various drum handling and handling operations. Once this first phase is completed, an additional dust suction point, consisting of 15 meters of flexible tubing, is switched to allow adequate cleaning of the mechanical parts involved.
During the filling of the BRUT container, a suction downpipe is connected by piping to two annular hoods located near the filling area, while an additional suction downpipe is interconnected to a conical hood located near the container emptying area, without getting in the way of the handling steps.
Finally, in the renewed FIN container emptying phase, the dust extraction system consists of a suction downdraft connected by piping to two annular hoods located near the filling area.

Dust extraction equipment for the Kourou Space Center
Regulus, a French company owned by Avio and Ariane Groups and a global leader in the production and refueling of solid propellants for space rocket engines, has requested from Coral a dust extraction system that could be used inside the Guyanese Space Center in Kourou, Europe's main space rocket launch site.
To reduce the emission of ammonium perchlorate into the air, proportionately sized booms and fume hoods were installed near the perchlorate containers, positioned so as not to hinder emptying and filling operations, with a total flow rate of 6,000 cubic meters per hour.
The industrial extraction system, designed for the client company, has its heart in the main manifold, which allows the convergence of the different sources of polluted air toward the Coral Aircom bag filter, used in its Atex version and certified to perform suction and filtration of potentially explosive dust. The filter is coordinated with a 15 kW Coral PRA 360/2 centrifugal electric fan, also suitable for explosion risk, which enables the expulsion of filtered and cleaned air into the outside atmosphere.
A high-performance centrifugal electric fan creates the necessary vacuum and conveys the filtered aeriform to the atmosphere via an exhaust stack.
