Embodiment Construction

[0027] A kind of condensate oil stench treatment process of the present invention comprises the following steps:

[0028] Step 1. Dust removal: pass the waste gas generated in the processing of condensate oil into the dust removal equipment for dust removal;

[0029] Step 2, desulfurization: desulfurize the exhaust gas after dedusting through the desulfurization system;

[0030] Step 3. Absorb organic matter: pass the desulfurized exhaust gas into the absorption tower, use the cooled absorbent to absorb organic matter in the exhaust gas, use the regeneration system to regenerate the absorbent rich in organic matter and rectify the organic matter, and pass into the absorption tower to re-absorb the organic matter in the exhaust gas;

[0031] Step 4, UV photolysis: pass the waste gas from which organic matter has been removed into the UV photodeodorization equipment for UV photolysis of the residual inorganic matter and residual waste gas in the waste gas, and directly discharg...

Abstract

The invention discloses a gas condensate treatment method, which has simple structure and not only can recycle organics from waste gas but also can remove other stinky substances. The method includes:performing dust removal to reduce influence on waste gas treatment in later period due to the dust; then desulfurizing waste gas through a desulfurization system in order to effectively remove inorganic sulfides from the waste gas; then by means of an absorbent, absorbing the organic substances from the waste gas through circulation, thereby increasing utilization efficiency of the absorbent andmeanwhile achieving continuous adsorption on the organic substances from the waste gas; finally, performing UV treatment to photolyze the inorganic substances and other residual substances in the waste gas. The method can remove all pollutants from the waste gas cleanly and high-effectively, purification efficiency being improved.

Description

technical field [0001] The invention relates to the technical field of petrochemical waste gas treatment, in particular to a condensate oil odor treatment process. Background technique [0002] Petroleum will produce waste gas during the refining process, mainly containing ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, dimethyl disulfide, carbon disulfide and benzene compounds, sulfides, VOCs, benzene compounds, these substances make organic or inorganic high Molecular chains of malodorous compounds. These malodorous gases containing organic and inorganic substances will seriously pollute the environment if they are directly discharged into the atmosphere. [0003] At present, the waste gas produced in petrochemical processing is mainly purified by combustion and deodorized at the same time. This method is suitable for dealing with combustible or decomposable organic gases at high temperature. The advantages of catalytic combustion are: small restrictions on th...
