Oversize particles are either recycled to main ultra fine or reground in a separate regrind plant, according to the viscosity requirement. The quality of the food-grade guar gum powder is defined from its particle size, rate of hydration, and microbial content. The source was traced to guar gum from India that was contaminated with pentachlorophenol, a pesticide no longer in use. PCP contains dioxins as contamination. The Catalysts portfolio includes fine-chemical catalysts and a full loop of metals-management services.
Proppant pack conductivity is maintained by utilizing a fluid that has excellent fluid loss control, such as the colloidal solids present in guar gum. The finer guar powders swells more rapidly than coarse powdered gum. Equipped with liquid nitrogen level sensor, insulated case and lid safety interlock switch for operator protection.
The guar seeds are dehusked, milled and screened to obtain the guar gum. It is typically produced as a free-flowing, off-white powder. It is classed as a galactomannan.
