TKPP Tetrapotassium pyrophosphate
TKPP Tetrapotassium pyrophosphate is a highly soluble, more environmentally friendly, low sodium alternative to SAPP. It is used as a replacement to Sodium Acid Pyrophosphate (SAPP) due to its low sodium content, where LWD is the preferred method of disposal.
For water treatment, as TKPP is potassium phosphate, it has higher water solubility compared to the corresponding sodium salts. It can be used both as a shale inhibitor and a corrosive inhibitor. So for activities where solids build-up is to be avoided, such as water systems. TKPP can be used along with other products for these systems.
TKPP’s main oil drilling application is for dispersing mud rings when water drilling and as a rapid thinner before cementing casing.
In water well applications, typically add one viscosity cup full of TKPP directly down the drill pipe on each connection. In the instances where there are areas with highly reactive clays, it is recommended to bring in a qualified individual to advise on any increased treatments that may be required. When using to thin the mud before cementing, mix as needed into the circulating mud system.
Tetrapotassium Pyrophosphate, Anhydrous (TKPP) Granular is a hygroscopic, white granule. It is used for its properties as a buffering agent, dispersing agent, protein modifier, coagulant, sequestrate, and mineral supplement.
TKPP can also be used as a soap and detergent builder. It is also a water softener and combines magnesium to sequester it from detergents. TKPP can reactivate detergents or soaps that have combined calcium to make insoluble scum.
Preparation & Procedures
Those working with Tetrapotassium Pyrophosphate, Anhydrous (TKPP) should wear appropriate Personal Protective Equipment, including dust masks and eye protection, while mixing all powdered products. Always try to avoid skin contact and do not inhale dust or allow contact with eyes. Never swallow or put TKPP into your mouth.
