  • Patent number: 9267074
    Abstract: Systems and methods for processing glycerol into one or more products and uses thereof are provided. In one or more embodiments, a method for treating soil can include applying a partially oxidized reaction product to a soil. The partially oxidized reaction product can be prepared by decreasing a pH of a mixture that includes glycerol and fatty acids to produce a mixture that includes a glycerol-rich portion and a fatty acids-rich portion. The glycerol-rich portion can be reacted with at least one of an oxidant and a catalyst at conditions sufficient to produce the partially oxidized reaction product.

  • Patent number: 5080779
    Abstract: Methods of diminishing the content of soluble and insoluble forms of iron from crude are disclosed. Crude and water soluble chelant are mixed prior to addition of wash water. After wash water addition, an emulsion is formed. After resolution of the emulsion, iron laden water phase is separated resulting in decreased iron content in the crude. In a two-step desalting process, water soluble chelant is mixed with crude separated from the resolved emulsion emanating from the first, upstream, desalter. After such mixing, fresh wash water is added, with the so-formed crude/chelant/wash water mixture being fed to the second, downstream, desalter, for resolution. Crude separated from the second desalter has substantially diminished iron content compared to crude fed to the first desalter.
