The circulated heat transfer fluid preferably comprises an alkali metal formate, most preferably potassium formate.
Pure potassium formate solution at any strength is produced.
Write the formula for each ionic compound: potassium formate, calcium formate, and ferric formate.
The fire extinguishing composition includes an aqueous solution of potassium formate.
The potassium citrate, which can be added as a solid to a potassium formate solution, enhances the density of said fluid and minimises any risk of caking which may be experienced if solid potassium formate is used.
Further, the composition can further comprise calcium formate, potassium silicate, etc. as an essential component, and a fluidizer, a corrosion inhibitor, a pH controller, etc. as an additional component.
This invention relates to an aqueous well servicing fluid comprising in solution a potassium formate characterised in that said solution contains in addition potassium citrate.
That is, preferably, the water activity of the potassium formate will be the same as or less than the water activity of the formation.
In an embodiment, the fire extinguishing composition includes an aqueous solution of potassium formate and an aqueous film forming foam.
In the method, the potassium formate is dissolved in the water phase of the emulsion in lieu of other less environmentally friendly salts such as sodium chloride.
The flaked and granular Potassium Formate inturn is used in the fields mentioned above and also as an additive to animal feed.
