Double-chamber reactor

In PCMRs, the reactors can be classified by the design and the atmosphere in which they are operated. A single-chamber reactor performs under a single atmosphere, while a double-chamber reactor consists of two separated chambers with different atmospheres. Generally, both reactors contain the same components, including a membrane electrolyte with two electrodes and an external power source. The external power source is connected between the anode and the cathode and takes control the direction of the reaction. 

The double-chamber reactor is a typical cell reactor in which the anode and the cathode are exposed to different gas mixtures. A schematic diagram of a double-chamber reactor with a proton-conducting membrane is presented in Figure 18.3.

Controlled catalyst circulation is one of the most important prerequisites for trouble-free operation of the FCC unit. Uniform circulation is ensured by controlling the differential pressure between the reactor and regenerator. The differential pressure in the existing plant is controlled by a differential pressure governor adjusting the position of the double slide valve upstream of the orifice chamber. 

This entire assembly was used as a rabbit and irradiated in a reactor for 3 minutes. After the irradiation, the rubber cap sealing the recoil chamber was punctured with a double-walled hypodermic needle, and air containing the recoiled krypton fission products was drawn out through the coaxial outer annulus of the needle. The effluent gases were passed through a trap paoked with glass wool, cooled in a dry ice-... 

The residue was ejected intermittently by a double lock discharge system illustrated in Figure 20. It featured two piston valves ( ram valves ) and an intermediate chamber. With the first ram valve open and the second ram valve closed, the chamber was filled with both solids and product vapor at the operating pressure of the reactor. Then the first ram valve was closed and the second ram valve was opened, thus leading to an ejection of the chamber content into a cyclone, where the solids were separated from the vapor. 

YSZ films were prepared a vertical cold-wall type CVD apparatus [II]. Source precursors of Zr(dpm)4 and Y(dpm)3 were vaporized at 483 to 593 and 393 to 473 K, respectively. The source vapors were carried with Ar gas into the CVD reactor. O2 gas was separately introduced by using a double tube nozzle, and mixed with precursor vapors in a mixing chamber placed above a... 

A vehicle is assumed to transport the reactor module and fuel chamber to the underground building through a double door with an isolation area.
