Abstract
A mixing tee assembly suitable for phosphate acid attack reaction is described. The mixing tee assembly comprises an outer pipe having a mixing end and a tee end, wherein a tee structure is formed near the tee end to connect with additional piping; an inner pipe comprising a nozzle end connected to a nozzle and a open end; wherein the inner pipe is lined with a corrosion-resistant material on its inside surface; wherein when the inner pipe is assembled within the outer pipe, the nozzle extends beyond the mixing end of the outer pipe by at least ⅓ of the inside diameter of the outer pipe.
Claims15
A mixing tee assembly configured to mix corrosive acid, comprising:
- a) an outer pipe having a mixing end and a tee end, wherein a tee structure is formed at the tee end and having two return acid inlets for a return acid stream to flow through two tee pipes into the outer pipe;
- b) an inner pipe comprising a nozzle end connected to a nozzle having multiple outlet slots arranged in a radial pattern and an acid inlet opposite the nozzle end;
- c) said inner pipe is lined with a corrosion-resistant material on its inside surface;
- d) said inner pipe is placed concentrically within the outer pipe with a circular nozzle stop ring placed between the nozzle and the inner pipe to prevent the nozzle from retracting into the inner pipe;
- and
- e) the nozzle extends beyond the mixing end of the outer pipe by at least ⅓ of the inside diameter of the outer pipe or by at least 4 inches.
A mixing tee assembly configured to mix corrosive acid, comprising
- a) an outer pipe made of high-density polyethylene (HDPE) having a mixing end and a tee end, wherein a tee structure is formed at the tee end having two return acid inlets for a return acid stream to flow through tee pipes into the outer pipe;
- b) an inner pipe comprising a nozzle end connected to a nozzle having multiple outlet slots arranged in a radial pattern and an acid inlet opposite to the nozzle end, wherein the inner pipe is made of a nickel-molybdenum-chromium alloy;
- c) said inner pipe is lined on its inside surface with a corrosion-resistant material selected from the group consisting of petrafluorethylene (PTFE), polypropylene, polyvinylidene fluoride or combinations thereof;
- d) said inner pipe is placed concentrically within the outer pipe, with a circular nozzle stop ring placed between the nozzle and the inner pipe to prevent the nozzle from retracting into the inner pipe and the nozzle extends beyond the mixing end of the outer pipe by at least ⅓ of the inside diameter of the outer pipe;
- and
- e) multiple fins attached to the outer surface of the inner pipe to centrally align the inner pipe within the outer pipe.
