Study on the Quality of Coal to Ethylene Glycol Products
coal to ethylene glycol product quality has not been fully recognized by the polyester industry,the main reason is that the coal ethylene glycol unique impurities,although GB/T 4649-2018 increased coal ethylene glycol impurity detection project,but in the failure to clear what is the polyester quality of material,on the upstream and downstream industry still lack of"authoritative"guidance.In this paper,the correlation between impurities of ethylene glycol produced from coal and process conditions is analyzed,combined with the influence of ethylene glycol products on the quality of polyester,and the quality of ethylene glycol products meet the requirements of polyester.
