  • Membrane-based gas separation process using ejector-driven gas recycle
    Patent number: 9017451
    Abstract: A gas separation process that utilizes ejector recycle with a membrane separation step in combination with a second separation step. The second separation step may be a second membrane separation, or may involve a different type of separation process. At least a portion of the non-product (i.e. residue) stream withdrawn from the second separation step is directed back to the ejector to form a processing loop. The ejector drives the gas flow in the loop and recycles the non-product stream to the first separation step.

  • Treatment of shipboard-generated oily wastewaters
    Patent number: 7018539
    Abstract: A process and apparatus for treating oily wastewater, such as bilge water or ballast water, generated on a ship. The process uses a combination of a centrifugal separation step and a membrane separation step, such as an ultrafiltration step. The membrane separation step uses a dense, non-porous filtration membrane. The process is able to remove both emulsified oil and dissolved oil from the wastewater to low levels.
