  • Methods and systems for bio-oil recovery and separation aids therefor
    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.
    Type: Grant

  • Method and apparatus for the enhancement of the biocidal efficacy of monoalkyldithiocarbamate salts
    Patent number: 9078436
    Abstract: The present invention provides a method of treating an aqueous system for biocide control, by adding an acidified solution that includes monoalkyldithiocarbamate salt and alkyl isothiocyanate to an aqueous system. A biocide feed system is also provided that is configured to generate a reproducible level of alkyl isothiocyanate. The method and system provide effective levels of alkyl isothiocyanate for rapid biocidal activity, along with levels of monoalkyldithiocarbamate salt which can decompose to form additional alkyl isothiocyanate and provide longer-term biocidal activity.
