Permeate hydrogen/steam mixture

In sub-configuration (A) hydrogen will permeate through the hydrogen selective membrane tube under the influence of a pressure difference over the membrane and it will be carried away with an inert sweep gas (steam). The partial pressure of hydrogen in the reaction mixture will decrease cmd the equilibrium will shift to the product side. 

CYANOETHANE (107-12-0) Forms explosive mixture with air (flash point 36°F/2°C). Reacts with water, steam, or acid, producing hydrogen cyanide fumes. Reacts violently with oxidizers, reducing agents, strong acids, caustic materials. Incompatible with A-bromosuc-cinimide, sodium nitrate. Attacks most rubbers and plastics, but polyvinyl alcohol has high resistance to permeation. 

The permeation zone outlet is a mixture of hydrogen and steam. The hydrogen is recovered by condensation, compressed and stored. A molten salt stream is sent to process the sweeping water boilers, then the residual sensible heat (molten salt is stored in cold tank at 290°C, as shown in Fig. 7.12) is used to produce electricity.The proposed plant is co-generative, as it is able to produce both hydrogen and electricity, and it is also a hybrid plant because of the simultaneous utilization of solar source and natural gas. Some heat recoveries are foreseen in order to reduce the heat...
