Using Disinfectants or Biocides [Category: Clean]
Textiles (Printing, Dyeing, or Finishing) [Category: Industry]
Both oil base and water base fracturing fluids are being used in the fracturing industry. Water base, which includes alcohol-water mixtures and low strength acids, make up the majority of treating fluids. The common chemicals added to these fluids are polymers for viscosity development, crosslinkers for viscosity enhancement, pH control chemicals, gel breakers for polymer degradation following the treatment, surfactants, clay stabilizers, alcohol, bactericides, fluid loss additives and friction reducer. /Hydraulic
Hydraulic fracturing uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow, increasing resource production. ... Chemical Name: Tetrakis hydroxymethyl-phosphonium sulfate; Chemical Purpose: Eliminates bacteria in the water that produces corrosive by-products; Product Function: Biocide.
