Abstract: A method for desalinating a liquid, including: contacting, within a hydrate former reactor, a feed gas stream including iso-butane in an amount ranging from above zero mol % to about 3 mol % and liquid seawater or liquid wastewater including a dissolved salt, wherein a temperature and pressure within the hydrate former reactor is controlled so that the feed gas stream and the liquid seawater or liquid wastewater form a hydrate slurry; separating hydrate particles from the hydrate slurry; and decomposing the hydrate particles into its constituents of water and gas or gas mixture containing iso-butane, wherein the water has a concentration of the dissolved salt that is less than that of the liquid seawater or liquid wastewater.

Abstract: Systems and methods are provided for pretreatment and upgrading of crude bio oils for further processing and/or use as fuel products. Crude bio oils can be treated by one or more of flash fractionation and thermal cracking to generate fractions suitable for further processing, such as further hydroprocessing. Blending of crude bio oil fractions with mineral feeds can also be used to reduce metals contents to levels suitable for refinery processing.
