  • Patent number: 7011713
    Abstract: The method of continuously collecting jelly compounds from jelly filled cable is performed by recycling operation of a solvent by repeatedly heating, cleaning and condensing the recycling solvent used to deprive the jelly compounds of the jelly filled cable. The solvent can be retrieved for reuse unlimited times, and the collected jelly compounds can be purified for reuse too. The method is energy saving with less consumption of solvent. Absolutely no worry of an additional public nuisance.

  • Patent number: 6846420
    Abstract: The present invention provides a process and an additive package for removing oil from solid material recovered from a well bore, e.g., drill cuttings and produced sand. In this process, the solid material is passed from the well bore to a separation zone. An aqueous acidic solution containing a polymer substituted with an amino group is introduced to the separation zone containing the solid material along with a halogenating agent and optionally one or more surfactants. The polymer, halogenating agent, and optional surfactant constitute the additive package. The polymer substituted with an amino group is preferably chitosan, and the halogenating agent is preferably a sodium hypochlorite solution. The mixture formed in the separation zone is agitated to cause a product of a reaction between the polymer and the halogenating agent to contact the solid material and remove residual oil therefrom.

  • Patent number: 6833149
    Abstract: A method for processing vegetable oil miscella is provided. The method includes steps of feeding vegetable oil miscella to a conditioned polymeric microfiltration membrane, and recovering a permeate stream having a decreased weight percent of phospholipids compared with the weight percent of phospholipids provided in the miscella. The retentate stream can be further processed for the recovery of lecithin. The polymeric microfiltration membrane can be conditioned for the selective separation of phospholipids in the miscella. A method for conditioning a membrane for selective separation of phospholipids from vegetable oil miscella, and the resulting membrane, are provided. The membrane which can be conditioned can be characterized as having an average pore size of between about 0.1&mgr; and about 2&mgr;.

  • Patent number: 6825156
    Abstract: A residue remover for removing polymeric material and etch residue includes 2-(2-aminoethylamino)-ethanol and optionally another two-carbon atom linkage alkanolamine compound, gallic acid or catechol, water, a polar organic solvent, and hydroxylamine. A process for removing photoresist or other residue from a substrate, such as an integrated circuit semiconductor wafer including titanium metallurgy, includes the steps of contacting the substrate with the above composition for a time and at a temperature sufficient to remove the photoresist or other residue from the substrate. Use of 2-(2-aminoethylamino)-ethanol in the composition and process provides superior residue removal without attacking titanium or other metallurgy on the substrate. The composition preferably has a flash point greater than about 130° C.
