Salt water geyser setup

Recommended Posts


I designed salt water geyser setup and I would like to show it to You. Maybe someone will get an inspiration from that.
Here is typical salt water geyser output:


Water is pretty hot: 95 C.

My idea was to avoid using desalinator but evaporate salt water into steam. Then superheat it even more to push the steam through steam turbines to get clean water at 95 C. Salt water is evaporated using heat from aqua tuner while the aqua tuner is cooling clean water from steam turbines. It looks like I achieved nice equilibrium using one aqua tuner with polluted water as a cooling medium and two steam turbines, producing 4kg of clean water per second. Setup will work only with really hot salt water ( > 94 C)  so salt water geyser and tank must be insulated well.

Hmm Ok. As salt water evaporates it leaves significant amount of salt:


Calculations were simple:


So 4301 grams of salt water will convert into 4000 grams of water and 301 grams of salt.

In this setup salt is being retrieved and cooled. Setup is automated and it should be fail-proof. However it is far away from being power positive.

Setup overview in current state where no salt water is available:


On the right top there is perfectly insulated (vacuum insulation) salt water tank. Below is an old tank (not part of this setup). On the left bottom there is a clean water cooling tank.There is vacuum above water as well. Key part of this setup is left top chamber.


Autosweepers, conveyor loader, aqua tuner - they are made of steel. There are gold or other well conductive tempshift plates through entire steam chamber to dissipate heat evenly.  There is thin (few kg) layer of crude oil inside turbine chamber for heat transfer as they are placed in vacuum.

Below there is piping overview:



Cooling loop is filled with polluted water. Liquid storage in water tank is not necessary. There is a side cooling loop for turbine chamber and it is currently set to 2000g/s. It could be set even lower as the temperature of steam turbines is about 68 C.

Output water from steam turbines reaches a valve that is open if automation requires. Otherwise it flows to clean water tank at the bottom.

Salt water from salt water tank passes through liquid shut-off valve and then through manual valve limiting its flow to 4301g/s. One liquid vent is used for salt water and clean water if necessary.


Here is an automation view:


Lets start from the bottom where there is a temperature sensor (Green when below 10 C). It is connected to temperature sensor (Green if above 230 C, should not happened) inside steam chamber and to liquid sensor (Green when below 10 C) attached to cooling loop. Finally through NOT gate it is attached to aqua tuner disabling it if any of those sensors became green.

Single atmo sensor (Green when below 10000g) connected directly to shut-off valve will redirect clean water from steam turbines again to steam chambers creating closed loop if there is less than 10000g of steam inside steam chamber.

Second atmo sensor (Green when below 20000g) coupled with hydro sensor (Green when below 20 kg) via AND gate is controlling salt water shut-off valve. So the salt water is flowing into steam chamber only when there is not enough liquid (below 20kg on the floor) and not enough gas (below 20kg below ceiling) inside steam chamber.

To get retrieve salt there are two autosweepers inside and one conveyor loader. Those are using significant amount of power when running constantly but they can be attached to cycle sensor to run then periodically.


Thank for reading!
