Discussion on the commissioning of oxygen-containing waste gas systems
The styrene unit aims to save energy and reduce consumption,fully recover and utilize the oxygen-containing waste gas from the ethylene glycol unit.Previously,the fuel gas for the styrene heating furnace was natural gas,which had a relatively high cost.Through optimization and transformation of the combustion of the oxygen-containing waste gas discharged from the ethylene glycol unit into the drum torch system and TO furnace,a new pipeline was added to the technical transformation for combustion in the styrene steam superheater.It has achieved the goals of energy conservation,emission reduction,cost reduction,and efficiency improvement,and can provide reference for optimizing energy conservation and consumption reduction in other styrene plants.
