A magnetic filter employs a magnetic core assembly that incorporates a plurality of exchangeable holder sleeves, each enclosing permanent magnets. Neither the sleeves nor magnetic bars are mechanically fixed to the filter housing. The magnet bars and holder sleeves are individually accessible. The number of holder sleeves in the magnetic core assembly is flexible. The magnetic filter in equipped with a screen that partially encloses the elongated holder sleeves to treat streams that contain degradation sludge, iron containing particles or flakes, and non-magnetic polymeric materials. In operation, a feed stream initially contacts the magnetic core assembly where paramagnetic contaminants become deposited onto the exterior surface of the holder sleeves under direct influence of strong magnetic field generated by the magnet bars. The mesh screen cylinder subsequently captures non-magnetic and weakly magnetic contaminants of a certain size before the cleaned stream exits the magnetic filter.

Magnetic filter for refining and chemical industries

A method and apparatus for increasing fractionation capacity and efficiency within an existing distillation column having preexisting mass transfer surface structures with a multiplicity of openings for vapor-liquid contact is provided. Some embodiments of the present invention include microdispersers, either individually or in combination, installed to convert target areas of select openings to achieve an optimal column performance without resorting to a full or partial replacement of the preexisting mass transfer trays. A kit for assembling an increased capacity and efficiency fractionation tray including installation instructions, one or more fastening devices and microdispersing bubble promoters and valves is also disclosed. A system for increasing capacity and efficiency of preexisting trays within a preexisting column is shown whereby microdispersers are used in combination with a revamp of the downcomer structures or other existing structures. The microdispersers may also be used in the construction of new fractionation towers.

Method and apparatus for improving a fractionation process

An apparatus for connecting adjacent tray panel of a fractionation tray within a distillation column tower for the separation between a vapor and liquid is provided. A first interlocking panel has an alignment area with at least one alignment slot toward the center of the panel and at least one alignment aperture located distal from the center of the panel. A second interlocking panel has an alignment tab with a valve perforation on the alignment tab. The alignment tab of the second panel is inserted into the alignment slot of the first panel at an angle. The gravitational force on the panel opposite the alignment tab of the second panel aligns the second panel within the horizontal plane of the first panel such that no bolts are required during assembly. Dispersion valves are inserted into the valve perforation to disperse the vapor and prevent weeping to the tray below and flooding to the tray above. The valve perforation also reduces the dead zone region between the interlocking panels to increase the capacity and efficiency of the fractionation tray and distillation column.
