en.Wedoany.com Reported - On May 18, Dongyi Group held the red-hot coke charging ceremony for the standby CDQ project of the second phase of Shanxi Dongyi Coking.
As a key green technical transformation project of Dongyi Group, the project carries the important mission of energy saving, carbon reduction, quality improvement, efficiency enhancement, and safe production assurance. Upon completion, the project will form a stable "one in operation, one on standby" operational pattern with the existing CDQ system, fundamentally enhancing the continuity, reliability, and risk resistance of coking production, and providing strong support for the long-term, safe, and stable operation of the unit.
The successful charging of red-hot coke marks the project's official transition from construction to production, representing a crucial step in the green and low-carbon development of Dongyi Group's coking industry. After the project is put into operation, it will effectively improve waste heat recovery efficiency, reduce energy consumption and pollutant emissions, perfect the production support system, further enhance the core competitiveness of the enterprise, and inject strong momentum into the group's high-quality development.
It is reported that the 1.44 million t/a 6.25 m stamp-charging coking project of Shanxi Dongyi Coal, Electricity and Aluminum Group Coal Chemical Industry Co., Ltd. mainly involves the construction of 2×65 ovens JNDX-6.25-16 type stamp-charging coke ovens with a carbonization chamber height of 6.25 m, supporting 1×230 t/h CDQ unit (with a standby 1×180 t/h unit) and 1×35 MW steam turbine generator set. The purified surplus coke oven gas will be sent to the Dongyi Coal Chemical Company's coke oven gas comprehensive utilization project to produce 250,000 t/a methanol and 80,000 t/a synthetic ammonia. The total investment of the project is 1.037 billion yuan, of which the environmental protection investment is approximately 264 million yuan.
