Carbon black tail gas internal combustion engine power generation method

Abstract

The invention belongs to the field of energy conservation, and particularly discloses a carbon black tail gas internal combustion engine power generation method. The power generation method comprisesthe following steps: step A, cooling carbon black tail gas to reduce the temperature of the carbon black tail gas to below 40 DEG C; step B, removing carbon black particles and dust impurities in thecarbon black tail gas, and drying the carbon black tail gas; and step C, conveying the purified carbon black tail gas to a gas generator set, burning the carbon black tail gas as a gas to generate electricity, and delivering the generated electric energy to a power grid after passing through a transformer. By adopting the process provided by the invention, carbon black tail gas is utilized for power generation, and energy waste is reduced.

Description

technical field [0001] The invention belongs to the field of energy saving, and in particular relates to a method for generating electricity from a carbon black tail gas internal combustion engine. Background technique [0002] Carbon black refers to a kind of amorphous carbon produced after incomplete combustion and pyrolysis of the residual products of coal chemical industry, such as coal tar and anthracene oil. Carbon black tail gas is the gas after carbon black is separated from carbon black flue gas. The composition of carbon black tail gas includes 3% CO 2 , 14%CO, 28%H 2 0.13%H 2 , 0.2% O 2 , 0.4%CH 4 , 42%N 2 , every ton of carbon black produced can produce 8000m of tail gas 3 -13000m 3 , and the calorific value of each cubic flue gas is 700Kcal, most of the carbon black tail gas produced by the carbon black plant is directly discharged, and a large amount of energy contained in it is wasted, and even causes environmental pollution, which is neither economical...
