The present invention utilizes mechanical vapor compression and/or thermal vapor compression integrating compression loops across multiple process stages. A sequential network of compressors is utilized to increase the pressure and condensing temperature of the vapors within each process stage, as intra-vapor flow, and branching between process stages, as inter-vapor flow. Because the vapors available are shared among and between compressor stages, the number of compressors can be reduced, improving economics. Balancing vapor mass flow through incremental compressor stages which traverse multiple process stages by splitting vapors between compressor stages enables the overall vapor-compression system to be tailored to individual process energy requirements and to accommodate dynamic fluctuations in process conditions.

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 method for preparing feed material for a catalytic depolymerisation process, the method comprising the steps of: separating feedstock into two or more feedstock streams based on one or more properties of the feedstock, introducing each of the two or more feedstock streams into one or more process vessels, processing the feedstock streams in the presence of a catalyst in the process vessels under conditions of elevated temperature in order to produce two or more intermediate feedstock streams, and blending the two or more intermediate feedstock streams to form the feed material.

Embodiments of the disclosure provide a system and method for producing light olefins from a crude oil. A crude oil feed is introduced to a crude distillation unit to produce a distillate fraction and a residue fraction. The distillate fraction is introduced to a non-catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. The residue fraction is introduced to a supercritical water reactor to produce an effluent stream. The effluent stream is introduced to a flash separator to produce a gas phase fraction and a liquid phase fraction. The gas phase fraction is introduced to a catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. Optionally, the residue fraction is introduced to a vacuum distillation unit to produce a light vacuum gasoil fraction, a heavy vacuum gasoil fraction, and a vacuum residue fraction. The vacuum residue fraction is introduced to a solvent deasphalting unit to produce a deasphalted oil and a pitch fraction. The deasphalted oil fraction, optionally combined with the heavy vacuum gasoil fraction, can be introduced to the supercritical water reactor in lieu of the residue fraction.
