AI Technical Summary

Technical Problem

Existing technologies are insufficient to achieve the 20mg/Nm3 emission standard for exhaust gases from oil tank areas and unloading platforms in petrochemical enterprises. Furthermore, there are risks of high-concentration instability and explosion. Conventional equipment has poor adaptability, and the economic added value of exhaust gas treatment systems is not fully utilized.

Method used

The waste gas treatment system consists of a cold diesel absorption tower and a VCU incinerator. The cold diesel absorption tower performs preliminary recovery of oil and gas through an absorbent, while the VCU incinerator performs thermal oxidation treatment. Combined with stainless steel materials and chilled water cooling technology, the absorption efficiency and safety are improved.

Benefits of technology

It has achieved economical, stable, and safe emission of exhaust gases from oil tank farms and unloading platforms, reduced oil and gas concentrations, improved treatment efficiency and safety, and reduced the risk of equipment blockage.

Abstract

The utility model provides a kind of waste gas treatment system, comprising: first waste gas delivery pipeline, second waste gas delivery pipeline, cold diesel oil absorption tower and VCU incinerator, the first waste gas delivery pipeline is connected with the cold diesel oil absorption tower, the cold diesel oil absorption tower is connected with the VCU incinerator by the second waste gas delivery pipeline. Most of the oil gas with high additional economic value is recovered by cold diesel oil absorption tower, and the characteristics of fast start and high processing efficiency of VCU incinerator are used to adapt to the waste gas characteristics of high concentration and high fluctuation in oil tank area and unloading platform. Thus, the purpose of economic, stable, safe and standard emission of waste gas treatment system with high concentration and high fluctuation in oil tank area and unloading platform is achieved.
