Dear all

I want your suggestion on the following method of chlor-alkin production as shown on the attached picture. Imagine a pump pushing brine through a pipe to a high velocity and transverse intense magnetic field to the pipe. according to Faraday's law:- moving ions in the presence of magnetic field with the right orientation will experience a force according to the right hand rule. Therefore, the sodium ions will concentrate on the upper side of the pipe as the brine solution pumped. On the other hand chlorine ions will concentrate on the bottom side of the pipe, then there will be a partition which dived the pipe in to upper and lower parts so the upper pipe part will contains more of sodium ions and the lower pipe part/partition will have concentrated chlorine ions.

As the this journey continue these two ions will encounter two electrodes which are externally shorted and hence the the sodium ions gain electrons and the chlorine lose electrons with a complete path for the electrons along the externally shorted wire.

The sodium ions are now sodium atoms so they react with nearby water molecule and forms sodium hydroxide and hydrogen while at the bottom side the chlorine ions lose electrons and forms chlorine molecules. As the two liquors get out of their corresponding pipes the gases also liberated. In general we will have sodium hydroxide solution and hydrogen at the top and chlorine and depleted brine at the bottom.

please see the attached picture

Thanks

I am not to convert mechanical to electrical. In chlorine, caustic soda manufacturing process from salt solution, the main problem is separating the chlorine from the soda and hydrogen when they are produced. Therefore, there must be a way of isolating these products from mixing so membrane is needed in membrane cell or asbestos diaphragm used. so i came with this idea (just for brain storming) whether it is valid for the intended purpose. As you see in the picture there physical separation between the upper and lower tube parts when salt dissolve in water it form two ions sodium and chlorine so as we pump the solution we are actually moving charged particles and charged particle motion under magnetic field create force on the particle so as the sodium move from right to left it will be pushed upward and any sodium particles tends to concentrate at the top of the pipe as they progress and the chlorine ions do the same thing but because they have opposite polarity they will concentrate on the bottom part of the pipe. Now we are separating the two ions and as they(the solution with the ions) continue the motion they will encounter a partition so the two ions separated. and when we put two electrodes there will be potential difference between the two electrodes which create current when shorted. the aim is not creating the potential difference but when we short the circuit each ions gain or lose electrons so we effectively separated the product from physical mixng
 
Where is the energy for your separation coming from? It's coming from the motive force that is pushing those moving ions against the resisting force of the magnetic field.
 
but do you think it will prevent the problem of mixing chemicals (such as mixing of generated chlorine with hydrogen) despite of being inefficient.
