An upgraded crude composition is provided, along with systems and methods for making such a composition. The upgraded crude composition can include an unexpectedly high percentage of vacuum gas oil boiling range components while having a reduce or minimized amount of components boiling above 593&#xb0; C. (1100&#xb0; F.). In some aspects, based in part on the hydroprocessing used to form the upgraded crude composition, the composition can include unexpectedly high contents of nitrogen. Still other unexpected features of the composition can include, but are not limited to, an unexpectedly high nitrogen content in the naphtha fraction; and an unexpected vacuum gas oil fraction including an unexpectedly high content of polynuclear aromatics, an unexpectedly high content of waxy, paraffinic compounds, and/or an unexpectedly high content of n-pentane asphaltenes.

Synthetic crude composition

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.

Hydrates for water desalination using iso-butane additive
