Patent ID: 7754057

Claim:
A chlorine dioxide solution generator comprising: (a) an anolyte loop comprising a reactant feedstock stream, at least one electrochemical cell fluidly connected to said feedstock stream, said reactant feedstock stream directed through said at least one electrochemical cell to produce a chlorine dioxide solution, and a stripper column, said chlorine dioxide solution directed from said at least one electrochemical cell into said stripper column, said stripper column producing a substantially pure chlorine dioxide gas stream by a vacuum; (b) a catholyte loop fluidly connected to said anolyte loop via a common electrochemical component; and (c) an absorption loop, said absorption loop fluidly connected to said stripper column, said absorption loop comprising a gas transfer pump, said gas transfer pump directing said chlorine dioxide gas stream exiting said stripper column to a chlorine dioxide absorber tank, said absorber tank having an upper portion and a lower portion connected by an injection line, said substantially pure chlorine dioxide gas stream entering said injection line and a process water stream entering said injection line, at least some of said substantially pure chlorine dioxide gas absorbing into solution with said process water stream to form a substantially pure chlorine dioxide solution wherein said substantially pure chlorine dioxide solution is neutral in pH and substantially free from reaction byproducts, said substantially pure chlorine dioxide solution entering said absorber tank from said injection line and exiting said absorber tank into a pressurized fluid stream of a fluid to be treated without introducing air into said pressurized fluid stream.
