Background technology
China is the complicated country of an energy resource structure, but at present, coal and oil product consumption exist always
In occupation of consequence in China's energy resource structure.In conventional petroleum technique, coking process is always a kind of important residual oil
Process, bears the lighting of heavy oil, and one of its product petroleum coke is widely used in steel, metal refining industry, at present
Progressively develop in terms of new material is produced.On the other hand, the rich coal resources of China, are recognizing coal resources high efficiency profit
With and grade of oil severeization and petroleum industry price upheaval, the development of Chemical Industry is increasingly by every country
Attention.One of important means that carbonization of coal is converted as coal, meeting product market will go to the high-quality of coke chemicals, together
When coke chemicals coke be always social heavy industry development high requirement product.Since 21 century, China's chemical industry stone
Oil and coal industry occur advancing side by side the trend of development, and either residuum coking or carbonization of coal is all born important
Mission, but coking industry is also one high consumption, highly water intensive and high pollution industry, deals carefully with technology waste gas and environment
Relation pair national economic stability and energy security guarantee have great importance.
The pollution control problem in chemical industry coking field can not be ignored as China's prevention and cure of pollution problem.It can be produced in coking
Raw many pollution environment and the toxic gas for damaging human physical and mental health, such as SO2And NOxAcid rain can be formed by being discharged into air
Or acid mist, while can also damage the ozone layer and wait simultaneously, be accompanied by during system is burnt greatly with hydrocarbon formation optical smoke
Amount dust pollution thing is discharged into air, once amount is big and spreads apart to suck respiratory tract by people, can cause breathing problem.
According to national environmental protection method and《Coking chemistry emission of industrial pollutants standard》Regulation, discharge waste gas in particulate matter, sulfur dioxide and
