Abstract

The invention discloses a method and device for production of synthetic crude oil by reducing the viscosity of heavy viscous oil. By introducing a new concept of mesoscale micro-interface chemical reaction and transfer process synergistic reinforcement, high-efficiency viscosity reduction of heavy viscous oil is realized, and also the heavy viscous oil can be modified. Compared with other technologies for production of synthetic crude oil by reducing the viscosity of heavy viscous oil, the method provided by the invention has the advantages of mild operation conditions, high efficiency, cleanness, high resource utilization rate, low cost and the like.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and relates to a method and a device for producing synthetic crude oil by reducing the viscosity of heavy heavy oil. Background technique [0002] The world is rich in heavy and heavy oil resources, such as Venezuelan heavy oil and Canadian oil sand bitumen, which occupy an important position in the world's oil extraction and processing. Due to the high viscosity of heavy and heavy oil, it is very inconvenient to mine, gather, transport, and process it. Generally, it needs to be pre-processed to reduce the viscosity before it can be sold to all parts of the world by pipeline or tanker. [0003] At present, the commonly used viscosity reduction methods mainly include the dilution method and thermal modification method. The blending method is to use a large amount of light oil, mix it into heavy heavy oil to reduce its viscosity, and then separate and recycle the light oil for use. Not only d...
