Abstract: Aiming at common challenges of traditional coking enterprises, such as the low energy utilization efficiency, the serious polluted environment, the short industry chain and the low value-added products, and so on, Tangsteel Meijin coking company developed a series of innovative coking process techniques. The new processes included mainly the 7m large capacity coke oven with wide oven chamber and multistage heat, the high temperature and high pressure CDQ of high efficiency power generation process, the efficient reuse process of waste water comprehensive treatment, the dust collecting process of the whole coking process, the solid wastes recycling process, the energy-efficient producing LNG process by using coke oven gas, etc. The new techniques are the highly efficient coke oven gas purification processes, the comprehensive technology of dust and poisonous gas control and negative pressure collection of exhaust gas, the refined distillation optimization technique of crude benzol extraction and the intelligent coking technology, etc. By using those new processes and techniques, Tangsteel Meijin coking company accomplished the overall optimization of coking process, and realized the the green transformation process of coking enterprises. New technologies would provide guidelines on getting rid of high energy consumption and high emission, and achieving cost-saving and profit-increasing and environmental friendliness for coking industry.
