the opening 518 the gaseous process media exits from the first cyclone 510a through piping 526 into the second cyclone 510b the second cyclone 510b is constructed in a similar manner as the first cyclone 510a particulate material entrained in the process media that was not separated during the first cyclone pass can be separated in the second cyclone 510b the gaseous process media then exits the second cyclone 510b to a bag filter not shown and then to a suitable collection device such as the tank 102 or the condenser 126 for example if analysis of the type and quantity of particulate matter separated from the process media indicates little blow off or loss of batch materials then direct recovery or recycling of the process media to a storage tank or condenser can be realized for that particular reaction process if material is being lost then additional filtering is indicated prior to recycling the process media to the storage tank or condenser the cyclones 510 could be used for experimental purposes for analyzing each reaction process or could be included in a production facility as part of a process quality control system in addition to entrained particulate material various reaction processes could involve the.
