Cooling tower alternatives to reduce evaporative losses

Published on by

I'm looking for some fresh ideas, innovations, traditional technologies which would enable me to eliminate cooling towers from industrial operations - minimising evaporative losses and maximising heat recovery. Would love to hear your thoughts.

  1. One of my client has 10 x 250 RT cell cooling tower. Client wants to get rid of fast evaporatioin in cooling tower. does any one know how to control fast evaporation and save water for maintaining water level in basin.

  2. Hello,

    I am overseeing your answer which will be "not my specialty, thanks for sharing" but "evaporation-condensation-rain" is not also your specialty yet you have digested it well, I come to take away a stupidity of your head.

     

    New discovery incredible to realize that we passed next for centuries, never heard

                                 THE RAIN IS FORMED IN 7 PHASES, NOT 3.

    "Lightning + thunder + rain = one operation"
    You will find the essence of what I advance as hypothesis in this message.

    HOW THEN ?
     

    1- EVAPORATION

    2- DECOMPOSITION of water vapor by photolysis (UVC: ultraviolet solar radiation of type C)

    hv + H2O → ↖H2 + O↗
    ↖H2 (2/29 = 0.068) and
    O↗ (16/29 = 0.551),
    All 2 lighter than the air, they escape in altitude, the lightest one will place the highest one.

    3- COMPRESSION (ascending and descending air currents - Opposition of 2 mechanical forces).

    4- IONIZATION under the effect of solar radiation, stirring and friction due to compression (all ionizing agents).
    H2 → (2H+) +2é-
    (called positive cloud) and

    O + 2é-(called negative cloud).

    5- EXPLOSIVE SYNTHESIS
    (O + 2é-) + 2H+ → H2O + lightning + thunder (the cloud is born, it is only there that one can speak of condensation).

    6- CONDENSATION    7- RAIN.

    The enigma flash + thunder-cloud-rain is resolved.

    If rain water were formed as we all learned,

    1- it would have rained much more during the warm seasons because the evaporation is more important than during the cold seasons.

    2- A dense, permanent fog from the ground up to the height of the current clouds would have formed. If you say that water in the gaseous state is invisible, I would say that its decomposition is even more (final stage).

    3- why do we expect rain when a storm is coming (lightning + thunder) if there is not an intimate relationship between lightning, thunder and rain?

    The theory "evaporation-condensation-rain", has no author, do you realize? !

  3. Hi,

    Recently, I had a seminar in Tehran university discussing the same issue to the students. The presented solutions were as follows:

    1. Reducing the number of heat exchangers as far as possible

    2. Reducing the number and the size of surface condensers as far as possible

    3. Using local chillers instead of water cooled heat exchanges

    4. Using Thermoelectric cooling (TEC) based coolers instead of water cooled heat exchangers.

    5. Making the best of use of steam coming out of the turbines instead of passing it directly to the surface condensers.

    6. Using high efficiency water cooled heat exchangers

    7. Relying on air coolers and closed circuit cooling towers

    8. Re-designing the process to reduce the need for lowering the process fluid

    9. Using fin-tubes to lower the process fluid's temperature in the inlet of the heat exchangers

    10. Awarding the compressors and process units to the vendors having low cooling water demands.

    11. Using the recycled water for the make-up water of the cooling tower

    12. Applying an interlock for the cooling tower fans to switch them off when the returning cooling water is not hot

    13. Using geothermal heat pumps (GSHP)

    14. Improving mandatory industrial water consumption restrictive standards

  4. Ground 'coolth' (the new word which is finding acceptance amongst engineers) is a very interesting source of renewable energy and this can replace cooling towers entirely. Contact me for details

  6. Can we just pump water through a pipe up to a desirable height and spray as larger droplets and collect back at the ground level like rainwater harvesting. This will minimize the cost and space required.
