摘要： A priming valve for priming a centrifugal pump includes a valve assembly separating an inlet chamber from an outlet chamber. The inlet chamber is fluidly coupled to an intake for the centrifugal pump and the outlet chamber is fluidly coupled to a priming pump. A control valve is provided to operate the valve assembly in order to fluidly connect the inlet chamber with the outlet chamber. While the valve assembly fluidly connects the inlet chamber with the outlet chamber, the priming pump can operate to replace air in the intake and the centrifugal pump with water.

The fluoroether carboxylic acid or salt employed comprises fluoroether carboxylic acid or salt having the formula below: [R1—O-L-COO−]Y+ wherein R1 is a linear, branched or cyclic partially or fully fluorinated aliphatic group which may contain ether linkages; L is a branched partially or fully fluorinated alkylene group which may contain ether linkages; and Y+ is hydrogen, ammonium or alkali metal cation. The process comprises adding stabilizer to the aqueous fluoropolymer dispersion to form a stabilized aqueous fluoropolymer dispersion and heating the stabilized aqueous fluoropolymer dispersion to decarboxylate the fluoroether carboxylic acid or salt to produce a fluoroether byproduct. At least a portion of the fluoroether byproduct is removed.
