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.

FLOCON 4800 is a liquid nutrient medium that can be easily diluted to the concentrations necessary for the operation of the mixing equipment. Direct injection of diluted solution into the oil reservoir without preliminary filtration is possible. It is compatible with the main surfactants and other liquid additives used in the three-component formulation in oil production. Special production technology can be given thermal stability up to 105 ° C (220 ° F). FLOCON 4800 is supplied as a nutrient medium or concentrate. In both cases, these are strongly pseudo-plastic solutions easily pumped by pumps.

Typical physical properties

After FLOCON 4800 has been dissolved for use as a mobility monitoring agent, TAKE MEASURES to protect it from bacteriological attack.

Particularly effective use of biocides and oxygen scavengers (the most common formaldehyde is HCOH). FLOCON is protected for transport and storage by the addition of 2000-3000 ppm HCOH.
