1. A filtration vessel, comprising: an outer housing defining a filtration chamber, the housing having an inlet port and an outlet port;a partition plate in the housing dividing the filtration chamber into an inlet chamber communicating with the inlet port and an outlet chamber communicating with the outlet port;a hole defined in the partition plate;a sleeve mounted in the hole in the partition plate, the sleeve having a solid ring portion lining the hole to provide a radial seal surface, the solid ring portion lining the hole such that the radial seal surface extends through the hole in the partition plate, and the sleeve further having an apertured portion with a plurality of flow apertures, the solid ring portion securing the apertured portion to the partition;a filter element removably installed into the sleeve, the filter element having a seal sealing radially against the radial seal surface. 2. The filtration vessel of claim 1, wherein the sleeve is a perforated sleeve providing the solid ring portion and the apertured portion, and wherein a plurality of holes, perforated sleeves, and filter elements are provided, each perforated sleeve mounted in one of the holes and each filter element mounted in one of the sleeves. 3. The filtration vessel of claim 1, wherein the partition plate has a thickness that is between 0.375 inches and 2.675 inches. 4. The filtration vessel of claim 1, wherein the partition plate has a thickness that is less than 1.5 inches. 5. The filtration vessel of claim 1, wherein the seal has an annular sealing flange and an annular base portion, the annular base portion carried by a first end cap of the filter element, and with the annular sealing flange having an annular terminating end spaced either radially inside an inner peripheral surface of the first end cap or radially outside an outer peripheral surface of the first end cap, wherein the seal is elastomeric with sufficient resiliency and flexibility to conform and seal to a non-round opening with up to at least 0.01 inches in a diameter variance from round. 6. The filtration vessel of claim 5, wherein the seal conforms to a generally round opening having a diameter up to at least 0.125 inches outside a design diameter of the radial seal surface. 7. The filtration vessel of claim 5, wherein the seal conforms to a non-round opening with up to at least 0.25 inch in a diameter variance from round. 8. The filtration vessel of claim 1, wherein an annular weld is formed between the solid ring portion and the partition plate thereby mounting and sealing the sleeve in the hole. 9. The filtration vessel of claim 1, wherein the sleeve is a perforated sleeve, further comprising a back support grid, wherein the back support grid further comprises a first alignment structure, and the perforated sleeve further comprises a second alignment structure, and the first alignment structure is adapted to receive the second alignment structure. 10. The filtration vessel of claim 9, wherein the first and second alignment structures are threaded, such that the perforated sleeve screws into the back support grid. 11. The filtration vessel of claim 10, further comprising a seal, wherein the seal is a flat gasket providing an axial seal between the perforated sleeve and the partition plate. 12. The filtration vessel of claim 1, wherein the sleeve is a perforated sleeve having a perforated portion extending from the solid ring portion, the solid ring portion extends between 1.5 inches and 2.5 inches along the perforated sleeve, the perforated portion extending between 2 and 80 inches. 13. The filtration vessel of claim 12, wherein the filter element has an outer diameter of between 2 inches and 10 inches, and a length of between 4 inches and 80 inches. 14. The filtration vessel of claim 13, wherein the perforated sleeve is made stainless steel having a gauge of between 14 and 20. 15. The filtration vessel of claim 1, wherein the hole is not machined but has a rough cut edge formed with one of the methods of stamping, torching, and cutting with a water jet. 16. The filtration vessel of claim 1, wherein the solid ring portion is connected to a flange, the flange extending radially outward and over an upstream face of the partition plate. 17. The filtration vessel of claim 1, wherein the apertured portion is non-removable relative to the partition plate without removal of the solid ring portion.
