Nano-Fix-Anticor™

  • GENERAL INFORMATIONcor

    NANO-FIX ANTICOR™ is anti-corrosion, weather-resistant enamel primer over the rust.

    The structure of NANO-FIX ANTICOR™ is a nano-sized silica sol and alyumozol (boehmite). Addition of the nanoscale sol NANO-FIX ANTICOR™ provides significant reduction of the organic binder while maintaining elasticity of the coating and a substantial increase in adhesion to various substrates, as well as the cohesive strength of the coating. The coating NANO-FIX ANTICOR™ practically doesn't shrink due to the high percentage of solids, and has high heat resistance.

    In covering NANO-FIX ANTICOR™ embodied a fundamentally new approach to corrosion protection, consisting in a complex chemical interaction between molecules of components with iron oxides and the atoms of the metal lattice. The primer has the ability to penetrate into cracks and pores of the metal while suppressing the started process of corrosion. Thus, solid metal chelate complexes with the polymeric component form on the surface of primer, effectively to protect the metal from an external impact. This mechanism of action allows NANO-FIX ANTICOR™ firmly tie layer of rust to 100 microns.

    High corrosion resistance of NANO-FIX ANTICOR™ minimizes the extensive work on the preparation of metal surfaces for painting, especially in hard to reach areas of structures, facilities or remote routes of pipelines, bridges, and also allows the use of NANO-FIX ANTICOR™ as an  independent coating .

    NANO-FIX ANTICOR™ consists of alkyd varnish, rust modifiers, fillers and target specific nanostructure additives.

    FEASIBILITY STUDY ON PRINCIPLES OF OPERATION, USE AND FEATURES

     NANO-FIX ANTICOR™ is a one-component composition for alkyd varnish with a modifier rust and special components, penetrating into the cracks and pores of the metal and stops the ongoing process of corrosion and prevents its spread over the surface, forming a dense, insoluble chelate complexes bind strongly to the polymer component of the NANO-FIX ANTICOR™ metal surface.

    The ability of NANO-FIX ANTICOR™ firmly tie layer of rust to 100 microns,and its high corrosion resistance minimizes extensive work on the preparation of metal surfaces for painting, especially in remote places of structures, facilities or remote routes of pipelines, bridges, and also use the NANOFIX ANTICOR™ as an independent coating in order to save money.

    For corrosion protection of pipelines and equipment of enterprises related to transportation and gas production, NANO-FIX ANTICOR™ has a distinct advantage over conventional painting, since stopping the ongoing process of corrosion improves the reliability of the gas supply system, whereas under normal enamel corrosion process under film continues until the complete destruction of the metal.

    In the car-building, particularly in the repair of rail cars, currently used expensive blast cleaning metal surfaces from corrosion products prior to painting. the use of NANO-FIX ANTICOR™ can partially or completely eliminate these costs while simultaneously increasing the service life paintwork.

    Now, in the manufacture of bridge structures are used very expensive imported (usually two component) coatings that require the most careful adherence to the mixing of the components, and the strict control of his personal protection during painting.

    The results of tests on the thermal aging (up to +230 C) indicate the possibility of using a primer in heating the housing and utilities sector and CHP.

  • PREVENTING FUEL evaporation from RESERVOIR USING COMBINATION OF NANO-FIX ANTICOR™ + RE-THERM™

    If isothermal storage of petroleum products becomes possible or the temperature fluctuations of gas space and the surface of the oil are significantly reduced, it is possible to completely eliminate breathing loss.



    During summer  diurnal  temperature of  reservoir  gas space reaches 30 ... 40%, and temperature of oil surface changes by 10 ... 15 ° C.

    The simplest and cheapest way to reduce daily fluctuations is painting of reservoirs and installation of protective screens. More complex and expensive methods are thermal insulation, irrigation of reservoirs and underground placement. Painting of reservoirs is permissible in any conditions as a method of controlling fumes and to protect a tank against corrosion. The color of reservoir paint has a significant impact on how much tank walls heat up and consequently on the oil contained in a reservoir.

    Gasoline, under the same conditions stored in tanks which are painted   in   different   colors,   has   the   following   temperatures: aluminum color - 11,5° C; gray - 14,6° C; minium - 16,6° C, green - 22°  C,  black  -  30°  C,  i.e.  petroleum  products  stored  in  tanks painted in bright colors with better reflectivity are much less prone to  daily   fluctuations   in   temperature.  White   has   the  highest reflectivity. When gasoline is stored in a horizontal white tank, the loss due to evaporation is half that of aluminum paint which is a common color for tanks at tank farms. Furthermore, white paint lasts for 3-4 years while aluminum (AL-177) lasts only 1.5 - 2 years.

    Shielding is ensured by planting deciduous trees near the reservoirs,  as  well  as  placing  reservoirs  under  awnings.  In southern areas reflective insulation of reservoirs is used which consists of a roof, a screen and side walls mounted at a distance of 0.1- 0.5m from reservoir walls. The use of shielding helps to reduce the loss of petroleum products by a factor of 2-3.

    Reservoir surfaces can be insulated with the use of materials with low thermal conductivity, such as foam glass, foam, cinder and  fiberglass.  However,  the  high  cost  of  covering  materials should be taken into account . Further, they need to be protected from rain and the overall level of control of the technical condition of the reservoir surfaces reduces.

    The most popular method to deal with fuel evaporation from a reservoir and overheating of low-temperature energy materials is often the method of thermal insulation with the use of a standard set of materials: classic insulation materials (rock wool, polyurethane,   polystyrene,   etc.)  and  a casing made of galvanized steel.
     
    This  method  is  quite  out  of  date;  it  does  not  meet  high standards of energy efficiency and has a number of negative aspects:

    • A complex and time-consuming process of installation, requiring highly skilled workers;
    • Large storage capacities are required;
    • High cost of materials and labor;- Inability to protect the upper portion of a reservoir;
    • Significant weight of insulation and the effect of the sail;
    • The inability to exercise control over technical conditions of the reservoir walls while it is in use;
    • The complexity of maintenance jobs;
    • Corrosion of metal under insulation;
    • Low rate of thermal reflection of solar radiation;
    • Lack of protection from condensation;
    • Vulnerability of insulation to moisture;
    • Low fire safety;
    • Accelerated aging of insulation material and rapid decline of its thermal characteristics;
    • Susceptibility to looting or vandalism

     
    With the adoption of federal, regional and local programs on energy saving new innovative solutions for thermal protection of reservoirs are required, and such solutions exist.

    Innovative  thermal  protection  systems  have  been  used  for these purposes for a number of years in many countries. One such system is the method of coatings developed and produced by the company "Innovative Technology" (Russia). The system consists of  two  coatings:   NANO-FIX  ANTICOR™  and   RE-THERM™. NANO-FIX   ANTICOR™  is   a   single-component   anticorrosive primer for rust.


    NANO-FIX ANTICOR™ primer offers a new approach to corrosion  protection  represented  by  a  complex  chemical interaction of molecules with components of the oxides of iron and atoms of a metal lattice. NANO-FIX ANTICOR™ is composed of a nano-sized  silica  sol  and  alyumozol  (boehmite).  Addition  of  a nano-sized  sol  into  NANO-FIX  ANTICOR™ contributes  to significant reduction of the amount of organic binder while maintaining elasticity of coating, and to a substantial increase in degree of adhesion to various surfaces, as well as to the cohesive strength of the coating. At the same time NANO-FIX ANTICOR™ practically doesn't shrink due to the high percentage of solids contained in it, and it is highly heat-resistant. Its operating temperature ranges  from  -70C  to +230  C. The primer  has  the ability to penetrate cracks and pores of metal while suppressing corrosion that has already begun. Thus solid chelate complexes containing  a  polymeric  component  of  the  primer  form  on  the surface    of    the    metal    and    effectively    protect    it    from    external exposure. This mechanism allows the primer to firmly bind up to
    100 microns of rust.

    The  excellent  anti-corrosion  qualities  of  NANO-FIX ANTICOR™ minimize efforts spent on   preparation of metal surfaces for painting, especially in hard to reach areas. The use of primer eliminates costly blasting of corrosion products from metal surfaces prior to painting. RE-THERM™ is a single-component water-based liquid thermal barrier coating consisting of a combination of silicone and ceramic microspheres that effectively reflect heat and sunlight.



    In addition to the "mirror" effect the material has a low coefficient of thermal conductivity, which does not fluctuate during operation. The coating is eco-friendly, leaves no waste, is vandal- proof  and  is  of  no  interest  to  looters  as  it  is  lightweight  and resistant to dynamic effects. It is fireproof during both installation and in operation. The coating is as easy to apply as ordinary paint, can be applied by any means and does not require highly skilled workers. An average coating thickness varies between 1.5 and 2 mm,  an  average  flow  rate is 1.5 liters per  1m2,  the weight of material is 0.55 - 0.6 kg / liter. A modified version adopted for winter conditions is also available, resistant up to -20° C.
    All materials and production are certified.

    The main advantages of using a NANO-FIX ANTICOR™ and RE-THERM™ coatings in combination are:

    • Minimum amount needs to be stored and protected;
    • Ability to carry out work (from cradles) without scaffolding;
    • Minimal preparatory work necessary, including elimination of expensive sandblasting;
    • Minimal cost of work and rapid return on investment;
    • Complete absence of damage to the environment at the time of application of coating and in the course of operation;
    • Great service life without change in performance;
    • Significant reduction in the total weight of thermal protection, reducing the load on the foundation;
    • Minimum load on the top of a reservoir;
    • Easy control of the state of welds and other elements of reservoir;
    • Complete protection against corrosion; 
    • Water proof, resistant to temperature drops and ultraviolet rays.

    It should be noted that classical thermal insulation due to its heat  resistance  only  slows  penetration  of  thermal  energy  from solar  radiation  into  the  reservoir  while  RE-THERM™  coating almost   completely   reflects   thermal   radiation   preventing   heat energy from penetrating the reservoir and heating up its contents, and not allowing it to cool or freeze in winter.




    An  example  of  application  of  a  similar  coating  system produced by Pemex Oil (Mexico).
     
    After a thorough analysis of this system the specialists focused on opportunities  for  reducing  maintenance  costs  by  using  a combination of coatings: Effective Primer and Liquid heat shield.



    This innovative coating system provided excellent insulation and corrosion protection and allowed an almost complete replacement of standard techniques including such labor-intensive and costly methods as sandblasting. Through the use of a thermal protection system a reservoirs service life could be extended from 4.5 to 10-15 years, and over a ten-year period the savings add up to $300 million.

    Maintenance costs were  significantly reduced,  so much so that  the  problem  of  evaporation  faded  into  the  background because of the ten-fold savings from the elimination of a number of maintenance   procedures    on   the   tanks.   The   increase in maintenance intervals saved much more money.


    Example of labour saving due to the use of an innovative coating system on a reservoir with a capacity of 80 thousand barrels:
     

    • Reservoirs are repainted every 4-5 years;
    • The cost of labor and materials for repainting one reservoir is approximately $65 thousand;
    • Innovative coating system allows to effectively increase repainting interval by 2 – 2,5 times, up to 10 years;
    • Savings on labor costs and materials for 10 years increase by 1 - 1.5 times;
    • Savings on every reservoir range from $65 thousand to $97 thousand over a period of 10 years;
    • For instance, for 3000 reservoirs, the total savings over 10 years would range between $195 and $300 million;
    • Total savings over 10 years from application of Effective primer + "Liquid heat shield" in order to prevent evaporation of fuel and  corrosion  of reservoirs range between  $ 213  and $ 322.5 million;
    • Given the cost savings from reduced evaporation and increased interval between repainting, the payback period will be
    • no less than 3.2 years or 68%.



    The following cases are among most prominent examples of the application of the system of coating:

    • Reservoirs and distribution pipelines transporting oil, fuel, liquefied hydrocarbons;
    • Reservoirs    and    distribution    pipelines    transporting    low- temperature energy sources;
    • Non-technological equipment used to prevent overheating from thermal radiation.



    Comparing a "new" system to a "traditional" one, here is a brief summary of their dissimilarities:

    • Traditional: cumbersome, expensive and time-consuming;
    • New: eco-friendly, cost-effective and energy-efficient.


    Today, a similar technology is successfully used by various companies around the world. Many world-renowned companies added innovative technology into their standards for production processes and energy efficiency. Russia still has a long way ahead of  it,  and  innovative  materials  produced  by  "Innovative Technology"  would  greatly  contribute  to its  progress  down  this path.

    A comparison of the two types of insulation installation

    1. Affixing mineral wool insulation layer with metal pins.

    Insulation layer could be affixed with pins onto vertical and horizontal surfaces with large radius of curvature and onto flat surfaces (reservoirs used for storing oil and oil products, accumulating hot water, reservoirs for drinking water, and for industrial purposes including fire, metal trunk chimneys, and other large  equipment).  Pins  for  fixing  the  insulation  layer  can  be inserted (if brackets for pins are provided) or welded.






    2. Coating with liquid heat-shielding materials.
     
    Coating with liquid heat-shielding material could be used on all types and configurations of surfaces  similar to conventional paint.



    A comparative analysis of methods:

    Method of thermal insulation of reservoir walling with mineral wool slabs:

    1. Anti-corrosion treatment of a reservoir wall
    2. Mounting of brace fixtures.
    3. Applying 2 coats of paint on reservoir walls
    4. Installation of thermal insulation boards.
    5. Hydro, steam, mineral wool.
    6. Mounting of brace.
    7. Mounting of the cover layer.
    8. Two final coats of paint on reservoir

    An average service life of mineral wool insulation is about 5 years, during which the insulation properties invariably deteriorate and may even deteriorate during storage and installation.



    Using NANO-FIX ANTICOR ™ + RE-THERM ™ for thermal protection of reservoirs
    1. Anti-corrosion treatment NANO-FIX ANTICOR™

    2. RE-THERM™ coating

    Expected  RE-THERM™  service  life  is  15  years  with  no change in performance.
    Notes

    Insulation of industrial equipment, in addition to the energy saving, made it  possible to run technological processes within given parameters, to create a safe working environment for production, to reduce the loss of volatile oil stored in reservoirs, and to store liquefied gases in insulated  storage containers.
    When choosing insulation material, strength and deformation characteristics of the isolated object should be calculated and allowable load on bearings and other elements of insulated surface should  be taken  into  account.  So,  while  isolating  vertical  steel water, oil or petroleum products’ storage reservoirs, the bearing capacity of insulation shall not exceed 32-34 kg/m2.
    Fire safety requirements are defined by the rules of technological design of relevant industries subject to SNiP 41-03-2003    "Thermal    insulation    of    equipment    and    pipelines".    For industries such as gas, petrochemical, chemical, and fertilizer production, administrative rules allow use of only non-combustible materials and slow-burning insulation. When selecting materials, flammability  of  thermal  insulation  layer  and  protective  coating should be considered, as well as characteristics of insulating structures in fire in general.
    Fire hazard rating of insulating structures along with other factors depends on the heat resistance qualities of the protective coating and its mechanical strength under fire exposure. Non- combustible fibrous insulating materials, under certain conditions, can absorb combustible substances (petroleum products, oil etc.), which in turn may affect an object’s flammability  potentially  allowing  it  to  catch  fire,  which  its design should also account for.



    Looking at this picture you can clearly determine that new heat insulation system is more convenient for installation and operation.
    Durability of heat insulation depends on design features and operating conditions, including the location of the isolated object, mode of equipment operation, environment and the intensity of mechanical effects. Durability of insulation as a whole is largely determined by the durability of the protective coating.
    When designing foundations for containers significant savings could be achieved with  RE-THERM™: its weight is significantly less  than  of  conventional  insulation  structures,  thus  it  doesn't weight heavily on the foundation.
    Questionnaires are used to determine thickness of insulation layers of each object, and a technological solution and individually modified RE-THERM™ are produced based on the answers provided.
