Core Technologies for Waste Gas Treatment in Oil Sludge Refining

Core Technologies for Waste Gas Treatment in Oil Sludge Refining 

Basic pretreatment: Spray absorption (alkaline solution for acid gas/particulate removal), cyclone separation + bag filtration (dust removal for high-dust tail gas)

Advanced degradation: Activated carbon/molecular sieve adsorption (low-concentration VOCs), CO/RCO catalytic oxidation (medium-concentration, high efficiency, no secondary pollution), RTO thermal cracking (high-concentration/sulfur-chlorine containing impurities)

Unorganized emission control: Closed negative pressure collection (leakage prevention from source) + photocatalytic/plasma purification (odor removal at end)

Main process combinations:

Small & medium projects: Spray tower → activated carbon adsorption

Medium projects: Spray tower → molecular sieve adsorption concentration → catalytic combustion

Large projects: Spray tower → bag filtration → RTO

Unorganized emissions: Closed negative pressure collection → photocatalytic/plasma purification

Energy saving & recovery: Reuse purified combustible gas as pyrolysis furnace fuel; recover combustion waste heat for oil sludge drying
