    Abstract: A method and system for effectively desalinating a feed stream is provided. In one embodiment, a feed stream is desalinated by a Brine Forward (BF) desalination system, which comprises an enabling de-scaling step combined with a plurality of multi-stage flash (MSF) trains arranged in series, wherein the de-scaling step is conducted within a MSF first train at a top temperature. With the aid of the de-scaling step, the system obviates or reduces many of the well known disadvantages of the desalination practice along with their expenditures and environmental burdens. The elimination of otherwise intractable substantial operating and silent environmental costs of such disadvantages, in itself, may over defray the de-scaling step's cost and with greater benefits to the overall system's performance and distillate production. Furthermore, all of the products from the de-scaling step are commercially viable, and if desirable or necessary, all of the de-scaling step's additives are also recyclable.

    Abstract: The present invention provides a method for selectively separating a straight-chain conjugated diene with high purity from a mixture containing the straight-chain conjugated diene and at least one type of straight-chain olefin. The method involves separating the straight-chain conjugated diene from the mixture containing the straight-chain conjugated diene and the straight-chain olefin using a zeolite membrane composite. The composite contains a porous support and a zeolite layer formed on the surface and in the fine pores of the support, and the zeolite contains an alkali metal cation.

  • Patent number: 9834315
    Abstract: An aircraft fuel deoxygenation system includes a boost pump, a contactor-separator, and a centrifuge-separator pump. The boost pump is adapted to receive fuel from a fuel source and inert gas from an inert gas source, and is configured to mix the fuel and inert gas and supply a fuel/gas mixture. The contactor-separator is coupled to receive the fuel/gas mixture and is configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel with entrained purge gas and separated purge gas. The centrifuge-separator pump is coupled to receive the deoxygenated fuel with entrained purge gas and is configured to separate and remove the entrained purge gas from the deoxygenated fuel and supply the deoxygenated fuel and additional purge gas.

  • Patent number: 9783467
    Abstract: A process for treating an effluent gas stream arising from a manufacturing operation that produces an olefin or an olefin derivative to recover unreacted olefin. The process involves compressing the effluent gas stream, which comprises an olefin, a paraffin, and a third gas, to produce a first compressed stream, then directing the first compressed stream to a membrane separation pretreatment step. The permeate stream withdrawn from this step is enriched in olefin and is sent to a second compressor, which produces a second compressed stream that is then cooled and condensed. The condensation step produces a liquid condensate and an uncondensed gas stream. The uncondensed gas stream undergoes a second membrane separation step to produce another olefin-enriched permeate stream, which is recirculated within the process prior to the second compression step, and an olefin-depleted residue stream, which may be purged from the process.

  • Patent number: 9770678
    Abstract: Described is a method for vacuum degassing of a liquid such as a solvent for a liquid chromatography system. The method includes modulating application of a vacuum to a fluid channel of a degasser so that each volume of a liquid drawn from the degasser experiences a residence time that is equal to the residence times of the other volumes. The residence time is determined as a time that the volume resides in the fluid channel under application of the vacuum and to a magnitude of the applied vacuum. The method is advantageous for use with liquid chromatography systems where differences in the diffusion rates of solvents into the degasser vacuum can otherwise introduce error into the composition gradient of a mobile phase.
