Abstract:
In view of the high energy consumption issue existing in the operation of coal-to-ethylene glycol production enterprises,this paper com- pares different industrial design schemes in the reaction and distillation systems of such enterprises,analyzes the merits and demerits of these schemes in energy consumption during operation,combining the actual engineering construction and industrial operation experience,and puts for- ward the industrial design scheme which is more conducive to energy saving,and briefly introduces the emerging energy saving technologies at present as reference for the coal-to-ethylene glycol production enterprises to promote energy-saving transformation.
