The energy efficient and environment friendly equipment for the fresh water production using environment energy

The energy efficient and environment friendly equipment for the fresh water production using environment energy
Novelty
The search for less expensive equipment of the fresh water production is one of the global challenges of the XXI century. As known, 97.5% of the world water reserves on the Earth is a share of salty waters of the seas and oceans. Therefore, the sea water is commonly used to produce the fresh water. The modern equipment for the sea water desalination is characterized by high cost and power consumption, their design is complex and imperfect.
Primary goal of this project is development the new generation of energy efficient and environment friendly equipment to produce fresh water from the sea water, atmospheric air, as well as the fresh water extraction from industrial drains using environment energy or the low potential energy sources. This device is based on a new principle - thermodynamic cycle named as a Maisotsenko Cycle (M-cycle), which is not based on the water evaporation and condensation, but using the naturally produced psychometric temperature difference (psychrometric energy) which is derived from the solar energy. Such the psychrometric energy is available throughout the world and is the driving force of the water evaporation and condensation. The project will be carried out using the fresh water production equipment from the sea water, however this approach has a great potential to be employed in some important industrial sectors of Ukraine - in the petrochemical industry (new technology for the light fractions production of the oil), in "softening" of the underground ‘hard’ water, in pharmaceutics during dehydration products, in medicine and in others. Also, a series of compact and energy-efficient small size desalination plants with power from 10W to 60 kW for military applications, using the solar energy, can be created using the new proposed principle

The proposed technology cheaper, easier, smaller and more convenient in usage
The technology is absolutely new proposal on the market
Implementation of technology is economically reasonable

The all modern desalters consume a lot of energy. Currently, the commonly used technique used in an industry is the distillation, which includes the fresh water evaporation and its further condensation, which requires about 2 kWhe energy to produce 1 m3 of the fresh water. The other techniques, such as the reverse osmosis, vacuum distillation, mechanical techniques and some other are characterized by the cost which is ranging from 1 to 20 kWhe.
The design of equipment to be developed in this project is based on the new approach (the energy in form of the environmental psychometric temperature difference, or psychometric energy), which allows create the mostly energy-efficient equipment using in its design only a low power fan to transport the atmospheric air through the evaporation and condensation passages.
The Maisotsenko Cycle to desalinate the salt water was recently used in the U.S. Patent № 8,613,839 B2 (2013). However, this design was not received industrial applications due to the large weight and volume, low air velocity in the evaporation and condensation passages (1-2 m/s) and the evaporated water film separation. A new approach of the M-Cycle application, proposed in this project, allows to increase by the order the air speed in the evaporation passage due to air swirling and significantly elevate the water evaporation rate due to the water-by-swirling air barbotage in the narrow annular space between the wet passage wall and coaxial porous insert through which both the air and water are able to penetrate. This design has a number of basic "know-how", proposed by the authors, which will be patented in the near future. The author's calculations, based on the preliminary experiments, have shown that production of 1 m3 of the fresh water requires only 0.1 ... 0.2 kWhe that is less of the reverse osmosis technology widely used in the practice. The share of the fresh water in the final product is 99% using the M-Cycle, while using the reverse osmosis technique it is only 95%. Design of equipment, based on M-Cycle, is more simple, more compact, and easier in operation. It is assumed, the cost of the proposed equipment is 2 ... 3 times less than the cost of all other desalters because of the material to be used in the proposed design is the plastic.

Solved problems
All modern desalters have a high cost, low efficiency and productivity, their design is complex, and the quality of the receiving the fresh water is not high enough. The proposed equipment is environment friendly and energy efficient. The cost of its production and operation is a few times less than all currently known desalination plants, because this approach is based on a new principle, which use the environment energy in the form of psychometric energy.

7. Markets
According to the World Health Organization, more than 800 million people have little or no access to the fresh water, and more than 500 million ones suffer from poor water quality. Algeria, Libya and Kuwait are almost fully importing the fresh water for human consumption. Technologically developed countries, such as Singapore and Malaysia receive the fresh water from China. Thus, the scarcity of the fresh water has now become a serious global problem. The world market capacity of desalters in 1995 was estimated as $3 billion of USD. By the year 2015, the world market demand for desalination plants will grow to $12 billion of USD.

Competitors, substitute goods, entry barriers
The main competitors in the world market are manufacturers of desalters, such as IPO NovaSvit (Ukraine), Alfa Laval (Sweden), Asqua Filtron Equipments (India), Armator (Russia), Alfarid Co (Egypt), Idromar (Italy) and others. The equipment of these companies is mainly based on the electrodialysis technique and has a high cost. None of the companies apply the Maisotsenko Cycle in design. The prototype design can be copied, however the exact design scaling is impossible, as many mistakes will be made and equipment has no the necessary parameters and performance. Entering the world market is always a challenge, but we hope the fundamentally new approach, using the environment energy, and high energy efficiency will provide the high competitiveness of our equipment.

Risks of the project and anti-risk activities
The project has no technical and technological risks. The idea of new equipment (desalter) is based on the well-known scientific positions of thermodynamics. Some risk is available to enter into the market and compete with the leading manufacturers of desalters (political and macroeconomic risk). The constant demand for the fresh water, low cost of equipment proposed, and low cost production cost of the fresh water will allow to compete with Ukrainian and international manufacturers. The Ukrainian market is quite a capacious enough. The regions with relatively dry climate and high ambient temperatures are the most interesting market for the equipment of this type. The analysis has shown that almost 90% of the regions of the world regions meet these basic requirements (Ukraine, Africa, Australia, Central America).
