Abstract:
In a metal ion elimination filter 14 for elimination of any metal ions in fuel 2, a filter body 16 filled with ion-exchange resin 15 for adsorption of metal ions through ion exchange is incorporated in a fuel feed passage (feed conduit 9) from a fuel tank 1 to an injector 5. A fuel return passage (return conduit 13) for return of the excessive fuel 2 in the injector 5 to the fuel tank 1 is passed through the filter body 16 to heat the ion-exchange resin 15 with waste heat of the returning fuel 2.
Abstract:
The ion exchange capacity of resin in an ion exchange column can be increased by applying a magnetic field to the resin while the ion exchange procedure takes place. The magnetic field may be generated in a variety of ways. Apparatus for practicing the invention may include permanent magnets, either stationary or movable, or an electromagnet or electromagnets arranged with respect to an ion exchange column to create a magnetic field in the resin in the column. When using an electromagnet, magnetic material, such as a cast iron rod or bar, is placed in the resin bed to direct and concentrate the magnetic field in the resin.
Abstract:
An improved process for regenerating the ion exchange resin in a water softening system. The process substantially reduces the amount of water and salt required for regeneration of the resin. The process includes the steps of venting the resin tank to the atmosphere and draining eventually all of the water from around the resin. Next, a brine solution is added to the resin tank. This is allowed to remain in contact with the resin until the resin is regenerated, preferably aided by energizing a vibrator positioned on the exterior of the tank. Next, the brine solution is drained from the resin tank which is then filled with water to rinse the brine from the resin. After rinsing, the resin is ready for use.
Abstract:
A method of cleaning contaminated resins for reuse comprises establishing a countercurrent flow between the contaminated resin and a carrier fluid for carrying the removed contamination from the resin and applying ultrasonic energy to the countercurrent flow with the countercurrent flow being conducted so that a region of turbulence is achieved where the ultrasonic energy is applied. A cleaning apparatus has means for introducing a contaminated resin and means for introducing a carrier fluid to a treatment zone in a countercurrent flow, means for collecting cleaned resin from the treatment zone, means for removing the carrier fluid from the treatment zone, and ultrasonic energy means for applying an ultrasonic energy field to the countercurrent flow in the treatment zone.
Abstract:
The present disclosure relates to methods of removing halides from a reactor effluent comprising treating the halide containing carbonylation product with a resin or material comprising a metal ion with a metal loading of greater than 15 wt % are provided herein. In some aspects, the methods involve treating the halide containing carbonylation product with a silver loaded resin which comprises a loading of greater than 15 wt % of silver to remove inorganic or organic halides.

Abstract:
An ion exchanger according to a non-limiting embodiment may include an open cell polymer support and a microporous polymer matrix charged within the open cell polymer support. The microporous polymer matrix includes an ion conductive polymer. The ion conductive polymer may be obtained by polymerizing monomers having at least one ion exchange functional group and at least one cross-linkable functional group with a cross-linking agent having at least two cross-linkable functional groups.
Abstract:
An ion exchanger vessel having a housing for receiving an ion exchange material and an inlet line and a discharge line in the housing for feeding and discharging a liquid to be passed through the ion exchange material. To heat the liquid, a heating medium is guided through the ion exchanger vessel, such that the heating medium is separated from the liquid to be passed through the ion exchange material.
Abstract:
Process for the on-site purification of an aqueous hydrogen peroxide solution, in which the solution is made to pass through a resin bed capable, at least partially, of adsorbing or absorbing the impurities present in the solution. The hydrogen peroxide solution is injected into the resin bed and passes through the latter at an approximately linear velocity preferably of between 10 m/h and 50 m/h and more preferably between 10 m/h and 20 m/h, while the resin bed is kept substantially compacted for at least 50% of the time during which the solution is being purified by coming into contact with the said resin.
