Through the study of acrylic acid process,the tail gas circulation technology combined with practical operation experience was developed.Using cycle gas instead of water vapor,the concentration of acrylic acid in the absorption tower was increased,while the utilization of propylene was improved.This process had significant effect of energy saving,emission reduction,cost reduction,and efficiency.After the off gas circulation process used in 60 000 t/y acrylic acid plant,it achieved good results,and brought large economic benefits for company.
