An integrated method and an integrated device for heavy oil contact lightening and coke gasification are provided. The integrated method uses a coupled reactor including a cracking section and a gasification section, and the integrated method includes: feeding a heavy oil material into the cracking section to implement a cracking reaction, to obtain a light oil gas and a carbon-deposited contact agent; passing the carbon-deposited contact agent into the gasification section, so as to implement a gasification reaction, to obtain a regenerated contact agent and a syngas; and discharging the light oil gas and the ascended and incorporated syngas from the cracking section, to perform a gas-solid separation, so that the carbon-deposited contact agent carried is separated and returned to the cracking section, and a purified oil gas is obtained at the same time.

This disclosure provides systems and methods that utilize integrated mechanical vapor or thermal vapor compression to upgrade process vapors and condense them to recover the heat of condensation across multiple processes, wherein the total process energy is reduced. Existing processes that are unable to recover the heat of condensation in vapors are integrated with mechanical or thermal compressors that raise vapor pressures and temperatures sufficient to permit reuse. Integrating multiple processes permits vapor upgrading that can selectively optimize energy efficiency, environmental sustainability, process economics, or a prioritized blend of such goals. Mechanical or thermal vapor compression also alters the type of energy required in industrial processes, favoring electro-mechanical energy which can be supplied from low-carbon, renewable sources rather than combustion of carbonaceous fuels.

A system for purifying petroleum or oil shale is provided. The system includes a pressurized cracking tank configured to receive petroleum or crushed oil shale; and a rotary kiln configured to receive product from the pressurized cracking tank.

The invention is an integrated process for treating residual oil of a hydrocarbon feedstock. The oil is first subjected to delayed coking and then oxidative desulfurization. Additional, optional steps including hydrodesulfurization, and hydrocracking, may also be incorporated in to the integrated process.
