Abstract
The invention relates to the field of chemical industry, and concretely relates to a processing technology of oxidation exhaust of a PTA apparatus. The processing technology of the oxidation exhaust of the PTA apparatus provided by the invention is simple in technology and low in operation cost, can absorb corrosive components in the exhaust through a high-pressure absorbing tower, and prevents pipelines from corroding by the oxidation exhaust.
Description
Technical field
The present invention relates to chemical field, concretely, relate to a kind of PTA device process for treating oxidized exhaust gas.
Background technology
In the process of commercial production p-phthalic acid PTA, contain the nitrogen about 95% in the tail gas, the oxygen about 2%-3% also has the organic matter of less than 1% in addition.Mainly contain contaminated environment and harmful compositions such as paraxylene, bromide, methyl acetate in the organic matter, and pipeline is had certain corrosivity.
Summary of the invention
To above-mentioned technical problem, the object of the present invention is to provide a kind of PTA device process for treating oxidized exhaust gas, the technology of this oxidized tail gas pipeline corrosion protection etching method is simple, operating cost is low, the most important thing is to eliminate the corrosivity of tail gas to pipeline.
In order to achieve the above object, the technical scheme of the present invention's employing is:
The present invention provides a kind of PTA device process for treating oxidized exhaust gas; Utilize high pressure absorber that the organic matter in the tail gas is absorbed, high pressure absorber is divided into two sections, and epimere washs with desalted water; Through the gas vent entering engine manifold of the gaseous component after the washing via the high pressure absorber epimere; The hypomere of high pressure absorber, absorbs with having corrosive bromide ion in the tail gas as spray with aqueous slkali, and treated liquid phase component is discharged via the liquid outlet of high pressure absorber bottom.
The technology of a kind of PTA device of the present invention process for treating oxidized exhaust gas is simple, operating cost is low, absorbs with having corrosive composition in the tail gas through high pressure absorber, has avoided the corrosivity of oxidized tail gas pipeline.
The specific embodiment
The present invention provides a kind of PTA device process for treating oxidized exhaust gas; Utilize high pressure absorber that the organic matter in the tail gas is absorbed, high pressure absorber is divided into two sections, and epimere washs with desalted water; Through the gas vent entering engine manifold of the gaseous component after the washing via the high pressure absorber epimere; The hypomere of high pressure absorber, absorbs with having corrosive bromide ion in the tail gas as spray with aqueous slkali, and treated liquid phase component is discharged via the liquid outlet of high pressure absorber bottom.
