Problems solved by technology

[0002] In general petroleum refining engineering, the heating furnace for heating raw materials usually passes through the radiation heating section first and then the convection heating section. However, for heavy components, it is more sensitive to heating. The traditional heating process brings Coking or even blockage of pipelines will lead to accelerated aging of equipment, decreased productivity, unstable product quality and decreased heating efficiency, etc.

Abstract

The invention discloses a heating furnace for processing aromatic hydrocarbon oils from heavy components of petroleum. The heating furnace comprises a furnace body, a flue and a gas nozzle, wherein the upper end of the furnace body is provided with a raw material pipe inlet and a steam pipe inlet in parallel, the lower end of the furnace body is provided with a raw material pipe outlet, and the steam pipe outlet is arranged on the middle of the furnace body. By means of staring the heating process by entering a convection section and ending the heating in a radiation section, the problem of coking can be reduce; heating temperature in the radiation section is more accurate, compared with a convection section; the heating temperature and temperature fluctuations can be well controlled, and the coking can be effectively reduced and avoided.

Description

technical field [0001] The invention relates to the technical field of a heating device and a heating process for processing aromatic oil with heavy components (oil slurry) in petrochemical industry, in particular to a heating furnace for processing aromatic oil with heavy components of petroleum. Background technique [0002] In general petroleum refining engineering, the heating furnace for heating raw materials usually passes through the radiation heating section first and then the convection heating section. However, for heavy components, it is more sensitive to heating. The traditional heating process brings If the pipeline is coked or even blocked, it will lead to accelerated aging of equipment, decreased productivity, unstable product quality, and decreased heating efficiency and many other problems. [0003] 1. The raw material for processing aromatic oil is the processed heavy component of petroleum. The material has high viscosity, high density and high heat sensit...
