Dear Dhaval,

is your project still an idea or have you already built a pilot plant?


What engineering services do you need? For calculations, sizing, drawings, construction, or anything else?


I tried looking on your homepage but I could not find any useful information.


Please, if you can be more specific we can maybe be helpful.


Thank you and good work.

Duilio Calura We need to calculations first to validate a system similar to MEDAD (https://www.medad-tech.com/technologies).  Our top operating temperature is 55C and condensing temperature ~1C.  We have significant amount of heat at 55C.  Does this help you move forward?  We have the vacuum available to boil water close to freezing temperature.

Dear Dhaval,

sorry, but the indicated link doesn’t work.

Anyway: how many stages (effects) have you intended to applicate?

Which is the possible Delta T between each stage?

You mentioned a boiling point at the last stage near 0°C. Yes, this is possible, but:

1) How much energy is needed for this purpose? A lot!

2) At this (low) boiling point, the steam volume is incredible very big and you will need a very large condensation surface.

3) To reach this very low vacuum you will need a cascade of different vacuum pumps and one of these must work with oil. it means that a well-functioning distillate trap should be implemented, if not, you have to regenerate very often the special oil.

4) Please, don’t forget the energy (electricity?) needed for the vacuum-skid.

5) What kind of medium do you intend to use for the last stage? Please remember that his must be colder than the steam itself (that is near the freezing point!)

 

That’s why a mass & energy balance must be calculated first!

 

There is a lot of remaining questions that must be cleared but if you can supply me first some information for these 5 points, it will be possible for me to understand your aim and intentions better. Thank you.

 

Best regards

Hello Dr. Calura,

 

Our system is very similar to https://www.medad-tech.com/technologies but we have a different terminal chamber.  We do need to integrate this into the MED process.  We were advised to have a mass and energy balance done first, but our assessment is that we have more than enough energy for the system.  Mass balance is not affected.

 

We can use all the services you mentioned for the MED process.  Subsequently, we have the potential to perform brine mining profitably with our process.  This flow needs engineering services as well.  The vacuum and thermal energy allows for low temperature evaporation of water from brine.

 

Please email me at Dhaval@lotus-pure.com for detailed information about the process.  Some aspects are patented and some are still patent-pending.

 

Thank you,

Dhaval
