Organic Coagulants

Coagulants destabilize the colloidal system by neutralizing forces of various nature that ensure its stability.

Coagulation was previously performed using inorganic coagulants, such as aluminum sulfate and ferric chloride (before the advent of synthetic organic polymers in the 1960s). At first, polymer coagulants were used as an additive to inorganic coagulants for more intensive flake formation. Today, polymer coagulants are used as basic coagulants, completely or partially replacing inorganic coagulants.

Flocculants

Synthetic polymers (polyelectrolytes), used for mechanical treatment of water from suspended and colloidal particles.

Flocculants – increase the size of flocs formed during coagulation, and agglomeration of suspended particles for their mechanical removal

Dispersants

Organic dispersants are synthetic polymers that exhibit a function inverse to flocculants, as a result of which they are often called deflocculants. SNF S.A.S. offers a wide range of dispersants and constantly conducts research in various industrial segments, which makes it possible to develop new deflocculants that meet the needs of consumers.

For many industrial products and processes, it is required that the solids be mixed in a finely dispersed state in a liquid medium. Such dispersions should be stable over a period of time.

Superabsorbents

Superabsorbent swells on contact with water and receives a bound amount of moisture, which is tens of times greater than their correct amount (for use in agriculture more than 500 times). The water-holding agents produced by us are used in the manufacture of personal care products, as well as in other industries.

Superabsorbent plays an important role in everyday life. Without the use of a moisture retarder, it is not possible to produce feminine hygiene pads, baby diapers, pads that make life easier when urinating incontinence. SNF has supplemented the range of FLOSORB products used in this field with a new water retainer with unique absorbing properties.

Thickeners

The acrylic thickener for the textile industry is produced by SNF, the world leader in this field.
Now SNF offers a number of FLOPRINT thickeners for pigment printing, based on know-how technologies, using the most advanced polymerization techniques.

Water softeners

Operating principle:

  • During the process of dehydrogenation, large amounts of ammonia and carbon dioxide are released due to the decomposition of organic materials.

  • These gases are very soluble in water. They combine with the formation of ammonium hydrogen carbonate (NH4HCO3). NH4HCO3 is a strong buffer with a pH below 7. At this pH, most of the calcium and magnesium ions are soluble. If a sufficient amount of phosphorus in the solution (HPO4 and PO4) is present in the solution, we have a system with all the necessary components for the potential formation of struvite (MgNH4PO4 · 6H2O).

  • A necessary condition for keeping the struvite in solution is a low pH (the lower, the more dissolved ions). Deposition of struvite depends on pH and concentration.

  • A sudden change in pressure or temperature will promote the release of dissolved CO2. This leads to an increase in pH and precipitates salts such as struvite, CaCO3, CaSO4.

  • FLOSPERSE™ is required to prevent salt precipitation. FLOSPERSE™ complex forms the metal ions. After that, these ions become inaccessible to precipitation from the solution.

  • An additional advantage of FLOSPERSE™ is that it will dissolve any salt already deposited in a given time period.

Defoamers

Defoamer is extremely useful, because although in most cases light foam does not cause any problems, however, heavy foam often leads to technological inconveniences. This problem extends from inaccurate reading of values ​​from instrumentation, such as temperature, level and sensor values, to poor mixing of chemical reagents in the reaction vessel and retention of products in the foam. Finally, the presence of foaming can adversely affect the customer’s opinion about the process. The presence of foam in sewage can lead to conflicts with local residents and authorities, even if the foam is absolutely harmless to people and the environment.

Xanthan gum

Xanthan gum is polysaccharides. These are biopolymers. They are produced by the microbiological action of bacteria xanthomonas campestris in a hydrocarbonate medium with the addition of protein and inorganic nitrogen. Biopolymer is extracellular mucus formed on the cell surface. The fermented nutrient medium is pasteurized to remove microbes, precipitated with alcohol, and then concentrated.

Xanthan gum is well-known for working well in highly saline brines. SNF received all technologies and patents for the use of xanthan gum FLOCON 4800, which is recognized by experts around the world as a product of the highest class for MND projects.

Surface active agents

Surface-active substance (SAS) are chemical compounds that, when concentrated at the interface, cause a decrease in surface tension.
Due to the washing, wetting, emulsifying, dispersing and other valuable properties of surfactants are widely used in various areas of the chemical industry.

Organic binding agents

Organic binding agents used in the iron ore pellet production process are the FLOFORM ™ series.

The formation of pellets typically requires the use of additives of binding agents to ensure sufficient efficiency of pellet formation steps, their calcination and reduction.
FLOFORM ™ is a series of organic polymers specially developed for the processes of iron ore granulation. They can completely or partially replace silica containing binders, such as bentonite.
FLOFORM ™ – polymers can be modified to achieve specific characteristics of iron ore. Polymers FLOFORM ™ are self-spreading powders that can be added directly to the concentrate so that the granulation process flows more gently.

Drilling reagents

Reagents for oil production have been used for many years to increase oil recovery (EOR, Enhanced Oil Recovery) to control the mobility of water introduced. Filling the polymer improves the efficiency of bulk cleaning, reduces the spill channeling and losses, increases oil production and lowers the cost of extracted oil.

Reagents for oil production of the FLOPAAM™ series from SNF are used in various areas of the oil industry to increase oil recovery, prepare drilling fluids, and strengthen well walls. For 15 years already, SNF has been developing a number of reagents for oil production. SNF holds a leading position in the production of oil recovery reagents. These products are designed to satisfy a wide range of conditions that occur in oil fields around the world.
