The invention relates to the technical field of carbon emission reduction of coal tar processing enterprises, in particular to a system and a process for reducing carbon emission of independent coal tar processing enterprises. Comprising a flue gas collection system, a flue gas cooling system and a CO2 absorption and desorption system. By improving the structures of a tubular furnace, a heat-conducting oil furnace, a reaction kettle heating furnace and a boiler chimney, the CO2-containing heating furnace flue gas is collected and cooled, then the CO2 is absorbed from the flue gas by using an absorption liquid, and then pure CO2 is desorbed from the absorption liquid in a desorption tower. The recovery rate of CO2 is greater than or equal to 85%, and the concentration of CO2 in residual flue gas can be as low as 50PPM. The purity of the recovered CO2 is high, the wet basis concentration of primary recovery treatment reaches 98.5% or above, and the wet basis concentration can reach 99.99% ...
