Application of RCO in Treatment of Regenerated Waste Gas from Natural Gas Deacidification Unit
VOCs can cause an increase in the concentration of ozone and PM2.5 in the atmosphere,and national and local standards have put forward requirements for the emission concentration and removal efficiency of VOCs.The deacidification unit of a certain oil and gas treatment plant adopts an activated MDEA one-stage absorption regeneration process,and the content of VOCs in the regenerated waste gas exceeds local environmental requirements,which makes it impossible to discharge directly.The unit applies RCO process technology to reduce the VOCs content in the regenerated waste gas to below 80mg/Nm3,so as to meet the local requirements for direct discharge to atmosphere.The RCO method is suitable for the treatment of low concentration VOCs,with the advantages of low NOx pollutant generation,small equipment volume and high VOCs treatment efficiency.However,in the design,it is necessary to fully consider production fluctuations and the accuracy of component concentrations to ensure that the RCO facilities after put into production can adapt to actual production needs.
