Abstract: A system for upgrading heavy hydrocarbon feeds, such as crude oil, include a hydrotreating unit, a hydrotreated effluent separation system, a solvent-assisted adsorption system, and a hydrocracking unit. Processes for upgrading heavy hydrocarbon feeds include hydrotreating the hydrocarbon feed to produce a hydrotreated effluent that includes asphaltenes, separating the hydrotreated effluent into a lesser boiling hydrotreated effluent and a greater boiling hydrotreated effluent comprising the asphaltenes, combining the greater boiling hydrotreated effluent with a light paraffin solvent to produce a combined stream, adsorbing the asphaltenes from the combined stream to produce an adsorption effluent, and hydrocracking the lesser boiling hydrotreated effluent and at least a portion of the adsorption effluent to produce a hydrocracked effluent with hydrocarbons boiling less than 180° C. The systems and processes increase the hydrocarbon conversion and yield of hydrocarbons boiling less than 180° C.

Abstract: To encode High Dynamic Range (HDR) images, the HDR images can be converted to Low Dynamic Range (LDR) images through tone mapping operation, and the LDR images can be encoded with an LDR encoder. The present principles formulates a rate distortion minimization problem when designing the tone mapping curve. In particular, the tone mapping curve is formulated as a function of the probability distribution function of the HDR images to be encoded and a Lagrangian multiplier that depends on encoding parameters. At the decoder, based on the parameters indicative of the tone mapping function, an inverse tone mapping function can be derived to reconstruct HDR images from decoded LDR images.

Abstract: A syngas generator is disclosed as an exothermic gas generator that can accommodate high combustion temperatures of a natural gas/oxygen flame. The generator consists of four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. These four sections may be arranged in series and tightly bolted together to form a gas-tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.
