A pressure cyclone is disclosed having a concave top head, wherein the concave top head has a substantially flat roof disposed in the interior of the cyclone vessel. An inlet is tangentially-coupled to the vessel and has an inlet nozzle disposed therein and configured to smoothly transition into the cyclone vessel to create a vortex that separates solid particulates from an incoming particulate-fluid suspension. In particular, the one surface of the inlet nozzle is tangent to the inner surface of cyclone vessel and another surface of the inlet nozzle is parallel and continuous with the substantially flat roof. An inlet casing is disposed around a length of the inlet nozzle and configured to transition from a circular casing to an elliptical casing along the length of the inlet nozzle, and couple to the vessel with the elliptical casing.

1. A cyclonic separator, comprising: a cyclone vessel having an inlet coupled thereto, the inlet configured to receive a particulate-fluid suspension comprising a fluid and at least one solid particulate suspended therein;an outlet tube mounted within the cyclone vessel and configured to remove the fluid separated from the particulate-fluid suspension separated fluids from the cyclone vessel;a concave top head coupled to the cyclone vessel and circumferentially-disposed about the outlet tube, the concave top head comprising a substantially flat cyclone roof disposed in an interior of the cyclone vessel; andan inlet nozzle disposed within the inlet and having a first surface and a second surface, wherein the first surface smoothly transitions to an inner cylindrical surface of the interior of the cyclone vessel and the second surface smoothly transitions to the substantially flat cyclone roof. 2. The cyclonic separator of claim 1, wherein the cyclone vessel is a cylindrical pressure-vessel configured to withstand internal pressures ranging from about 50 psi to about 800 psi. 3. The cyclonic separator of claim 1, wherein the inlet is tangentially-coupled to the cyclone vessel. 4. The cyclonic separator of claim 3, wherein the inlet comprises an inlet casing disposed around a length of the inlet nozzle, the inlet casing having a first end distal the cyclone vessel and a second end at or near the cyclone vessel, wherein the first end has a circular cross-section that transforms along the length of the inlet nozzle into an elliptical cross-section at the second end. 5. The cyclonic separator of claim 1, wherein the inlet nozzle is rectangular. 6. The cyclonic separator of claim 1, wherein the substantially flat cyclone roof comprises a series of pie-shaped refractory bricks. 7. A method of separating solid particulates from a particulate-fluid suspension, comprising: introducing the particulate-fluid suspension into a cyclone vessel via an inlet tangentially-coupled thereto, wherein the inlet comprises an inlet nozzle having a first surface tangent to an inner cylindrical surface of the cyclone vessel and a second surface substantially parallel to and continuous with a cyclone roof of a concave top head of the cyclone vessel and the particulate-fluid suspension comprises a fluid and at least one solid particulate suspended therein;creating a vortex within the cyclone vessel to drive the solid particulates toward the inner cylindrical surface and produce a reduced particulate loading particulate-fluid suspension; andremoving the reduced particulate loading particulate-fluid suspension from the cyclone vessel through an outlet tube disposed within the cyclone vessel. 8. The method of claim 7, further comprising operating the cyclone vessel at pressures ranging from about 50 psi to about 800 psi. 9. The method of claim 7, further comprising: disposing an inlet casing around a length of the inlet nozzle;transitioning the inlet casing from a circular cross-section at a first end of the inlet casing to an elliptical cross-section at a second end of the inlet casing along the length of the inlet nozzle; andcoupling the second end of inlet casing having the elliptical cross-section to the cyclone vessel. 10. The method of claim 7, wherein the inlet nozzle is rectangular. 11. The method of claim 7, wherein the cyclone roof is substantially flat. 12. The method of claim 11, wherein the cyclone roof comprises a series of pie-shaped refractory bricks configured to circumferentially-surround the outlet tube. 13. A pressure cyclone, comprising: a vessel having a concave top head, wherein the concave top head comprises a substantially flat roof disposed in an interior of the vessel;an inlet tangentially coupled to the vessel;an inlet nozzle disposed within the inlet and having a first surface and a second surface, wherein the first surface is tangent to an inner cylindrical surface of the interior of the vessel and the second surface is parallel to and continuous with the substantially flat roof;an inlet casing disposed around a length of the inlet nozzle, the inlet casing being configured to transition from a circular cross-section at an end distal the vessel to an elliptical cross-section at an end proximal the vessel along the length of the inlet nozzle, and couple to the vessel at the proximal end with the elliptical cross-section; andan outlet tube disposed within the vessel and sealingly coupled to the concave top head. 14. The pressure cyclone of claim 13, wherein the vessel and concave top head are configured to withstand pressures ranging from about 50 psi to about 800 psi. 15. The pressure cyclone of claim 13, wherein the concave top head further comprises a concave casing and a roof insulation layer, wherein the roof insulation layer is interposed between the concave casing and the substantially flat roof.
