PETROLEUM PROCESSING PROCESS AND APPARATUS Russian patent published in 2007 - IPC C10G11/06 B01J3/08 

FIELD: petroleum processing.

SUBSTANCE: group of inventions relates to processing of petroleum and liquid hydrocarbons and can be applied separately as rotary pump with mechanical cracking during pumping of crude oil in order to increase yield of low-molecular weight hydrocarbons and to lower viscosity. In a process of processing a mixture of liquid hydrocarbons, processing is accomplished via mechanical catalyst-free hydrodynamic cracking in at least one step in a single process space, which is centrifuge with cylindrical or conical rotor protected against external effects by a special system and having outlet pipes, wherein feedstock stream is continuously supplied to process space of rotating cylindrical or conical rotor; feedstock is stirred mechanically with the aid of rapidly rotating rotor provided with partitions and combs mounted thereon at the rotor rotation speed 8000-28000 rpm and pressure inside centrifuge up to 1.2 mPa; feedstock processing temperature is controlled by preheating it and also by heating or cooling front cover and space between rotor and centrifuge case, while processed feed is discharged over outlet pipes. An apparatus for implementation of above-described process is also provided.

EFFECT: enabled processing of crude oil at its production site, facilitated transportation thereof, and increased crude oil processing efficiency.
