Sand knockout for fracking fluids

A cyclonic sand knockout device comprising:

• a body having an inner cavity, wherein the inner cavity has a first end and a second end;
• a vortex finder having a first end and a second end disposed within the inner cavity, wherein the vortex finder is coupled to the body proximate to the first end of the vortex finder and proximate to the first end of the inner cavity;
• a dome disposed within the inner cavity having a first end, a second end, and an inner cavity, wherein the dome is coupled to the body proximate to the second end of the dome and proximate to the second end of the inner cavity;
• an inlet in fluid communication with the inner cavity formed within the body for introducing fluids into the inner cavity of the body;
• a first fluid exit in fluid communication with the inner cavity formed within the body proximate to the first end of the inner cavity;
• a collection chamber in fluid communication with the inner cavity formed within the body and coupled to the body proximate to the second end of the inner cavity;
• wherein the first end of the dome, the second end of the dome, and the inner cavity of the dome are each in fluid communication with each other and are in fluid communication with the collection chamber;
• wherein the vortex finder comprises a tubular member having a first end, a second end, and an inner cavity, wherein the first end, second end, and inner cavity of the tubular member are in fluid communication with each other;
• wherein the tubular member of the vortex finder has a plurality of flow apertures formed therein, each of the plurality of flow apertures being an elongated slit oriented along a length of the tubular member and being in fluid communication with the inner cavity of the body and being in fluid communication with the inner cavity of the tubular member;
• and
• wherein each of the plurality of flow apertures of the tubular member are located closer to the first end of the tubular member than to the second end of the tubular member.
