A kind of cokingization produces system VOCs comprehensive management of technology.
Background technique
VOCs refers to volatile organic matter/volatile organic compounds, is the important pollutant for leading to haze, serious shadow
Air quality, animal and plant growth and human health are rung.It is mainly derived from oil refining and petrochemical industry, chemical raw material and chemicals
Manufacture, the manufacture of chemicals bulk pharmaceutical chemicals, synthetic fibers manufacture, external coating, printing, shoemaking, Furniture manufacture, wood-based plate manufacture,
Main pollution in electronic components fabrication, textile printing and dyeing, plastics manufacture and the industries discharge exhaust gas such as plastic products, Life service industry
Object.Volatile organic compounds is divided into 8 classes: alkanes, aromatic hydrocarbons, alkenes, halohydrocarbon, esters, aldehydes, ketone by its chemical structure
With other chemicals.There is toxicity mostly and with stench, some or carcinogen, such as vinyl chloride, benzene,toluene,xylene
Deng.Moreover, most volatile organic compounds are inflammable, explosive, this brings many insecurity factors to enterprise's production.
Coking refers generally to the process of organic substance carbonization zoom, refers to high-temperature retorting in coal carbonization, in PETROLEUM PROCESSING,
Coking is the coked abbreviation of residual oil, refers to that mink cell focus carries out the cracking and condensation of depth under 500 DEG C or so of hot conditions
Reaction generates the process of gas, gasoline, diesel oil, wax oil and petroleum coke.In coking, a large amount of VOCs can be generally generated,
Serious pollution is generated to atmosphere, is administered although producing the VOCs that system generates to cokingization at present, regulation effect
It is not satisfactory.The various technical methods of VOCs processing at present include Ozonation, plasma cracking method and concentration incineration method etc.
Deng, the above method, all exist processing not enough thoroughly, the problems such as scale of construction is big, low efficiency, and the cost of part processing method is inclined
It is high.
Summary of the invention
The purpose of the present invention is to provide a kind of cokingization to produce system VOCs comprehensive management of technology, which can be effective
