Optimization countermeasures of coking industry chain based on material metabolism analysis
With the economic development area of Etok as an example,the material metabolism evaluation method was applied to evaluate,the metabolic pathway and metabolic efficiency of coal,water and energy in the coking industry.The results show that the water intake per ton of coke products in the coking industry is 1.11 m3 in the economic development area in 2023.The water-saving level is slightly lower than the industry's leading level(leading value of 1.1 m3 according to DB15/T 385-2020).The energy consumption per ton of coke products(by standard coal)is 136.46 kg,much higher than the access value requirement of 127 kg in Coking Industry Standard Conditions and the requirement of advanced value(less than 110 kg)in DB15/T 2232-2021.The path of improving the efficiency of material metabolism is thus proposed,including promoting the horizontal coupling of coking and related industries,strengthening the industrial chain of comprehensive utilization of coke oven gas,extending the industrial chain of crude benzene processing,and doing a good job in the industrial chain of coal tar deep processing.
