VOCs emission treatment method for chemical examination and analysis room of refinery enterprise

Abstract

The invention relates to the technical field of waste gas treatment, in particular to a VOCs emission treatment method for a chemical examination and analysis room of a refinery enterprise. The VOCs emission treatment method comprises the following steps that A, waste gas collection is conducted, specifically, waste gas is uniformly collected into a gas buffer tank through an air blower; B, first waste gas concentration adjustment is conducted; C, mixed waste gas compression is conducted, specifically, the mixed waste gas is compressed to 0.4 Mpa by a compressor; D, second waste gas concentration adjustment is conducted; E, regenerator combustion is conducted, specifically, the waste gas and main air are combined and then fed into a regenerator to be combusted; and F, catalytic cracking treatment is conducted, specifically, regenerated flue gas at the regenerator and unburned waste gas enter a desulfurization and denitrification system of a catalytic refinery device together, and it is guaranteed that tail gas emission reaches the standard. The VOCs emission treatment method overcomes the defects of existing waste gas treatment facilities of a chemical examination and analysis room, prevents VOCs from being discharged and polluting the environment, reduces the waste gas treatment cost of the chemical examination and analysis room, ensures safe and stable operation of equipment and improves the practicability.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a VOCs emission treatment method for a laboratory analysis room of a refining and chemical enterprise. Background technique [0002] The scope of application of the laboratory analysis room of refining and chemical enterprises is very wide. It mainly includes the specification analysis of raw materials and auxiliary materials of various production units in petrochemical plants, the quality control analysis and product quality analysis of intermediate products of production units, the analysis of medium indicators of public works, and the Supervise and inspect the quality of ex-factory products and other auxiliary tasks. The laboratory analysis room is usually equipped with various analysis rooms, chromatographic rooms, physical property inspection rooms, reagent libraries, sample rooms, balance rooms, high-temperature rooms and auxiliary rooms, etc. The experimental m...
