Abstract
A mixing valve assemblyis communicated with a dedicated tankD, storing therein a compatibilizer D, via an inlet valveand is also communicated with dedicated tanksA-C via three injection valves, the tanks storing therein auxiliaries A-C respectively. A chemical formulation is prepared by selectively injecting any one(s) of four chemical agents into the mixing valve assemblyby way of on-off control of the inlet valveand the injection valves and blending together the injected chemical agents. Then, the chemical formulation is pumped into SCF by a high-pressure pumpsuch that the SCF and the chemical formulation are mixed together to form a process fluid. Thus, the number of components of a high-pressure portion can be reduced to achieve a cost reduction of an apparatus. Furthermore, a pipe line for pumping the chemical agents is simplified.
