面对焦化行业微利时代以及国家对能源和环保重视的严峻考验,各焦化企业积极采取节能降耗、低碳环保的措施,确保企业能够在行业竞争中持续发展.针对现有的蒸氨工艺及现状,介绍了焦化企业直接蒸汽蒸氨、负压蒸氨、热泵蒸氨3种蒸氨工艺.通过对3种工艺在投资、能耗、环保以及能耗费用方面的比较得出:负压蒸氨法解决了直接蒸汽法蒸汽耗量大、废水多等问题,同时具有较好的经济效益.指出节能环保蒸氨工艺取代传统蒸氨是焦化企业发展趋势,符合循环经济环保策略.“,”Faced with coking industry small profit era and the crucible of state for energy and environmental protection,the coking enterprises actively adopted energy saving and low carbon environmental protection measures in order to ensure themselves sustainable development in the industry competition. In view of the company\'s existing steamed ammonia process and the present situation,three types of ammonia distillation technologies applied in coking enterprises were introduced,which were direct steam ammonia distillation,negative-pressure ammonia distillation and hot pump ammonia distillation. Through comparing investment,energy consumption,environmental protection and energy costs of three distillation technologies above,the conclusion was made that a series of problems,such as high consumption of steam and great amount of waste water could be solved,which could be caused by direct steam ammonia distillation using negative-pressure ammonia distillation,at the same time there was a good economic benefit. It was pointed out that energy-efficient,environment-friendly ammonia distillation process replacing traditional process will be the important trend of coking enterprises,according with the environmental protection and circular economy strategy.
