  • Patent number: 10060038
    Abstract: An anti-corrosion composition containing at least one fatty acid ester, at least one glycol, at least one ethylene oxide/propylene oxide (EO/PO) alkoxylate, at least one polyethylene glycol ester, and at least one modified lecithin is provided. An anti-corrosion composition also is provided which contains at least one fatty acid ester, at least one glycol, at least one sorbate, and at least one modified lecithin. A method of preparing an anti-corrosion composition is also provided. At least one modified lecithin can be blended with at least one fatty acid ester, at least one glycol, at least one EO/PO alkoxylate, or at least one polyethylene glycol ester, or any combination thereof. A method of inhibiting corrosion of a metal surface including applying an anti-corrosion composition to the metal surface in an amount effective to inhibit corrosion of the metal surface is further provided.

  • Patent number: 9328311
    Abstract: A method and system for bio-oil recovery from biomass are provided which includes adding at least one separation aid to stillage that contains oil to form a treated stillage prior to centrifuging the stillage, and centrifuging the treated stillage in at least one centrifuge to separate at least a portion of the oil from the treated stillage. The separation aid can contain at least one lecithin and at least one oil and optionally at least one surfactant having an HLB value of at least 6. Treated stillage products are also provided which can contain the indicated separation aid and recovered oil.
