摘要: 为进一步提高芳烃联合装置经济效益、降低装置运行成本,对某公司芳烃联合装置的能耗构成进行了分析,确定了芳烃联合装置能耗的主要来源构成:燃料(燃料油、柴油、燃料气、液化气、外购液化天然气等)消耗占比为60.56%,蒸汽消耗占比为29.89%,电力消耗占比为8.20%。进一步,通过对装置用能过程进行分析,明确了装置节能的主要努力方向在于增加芳烃产量和控制燃料、蒸汽、电力的消耗。结合实际生产运行情况,探讨了芳烃联合装置的节能降耗方法,结果表明:通过采取增大装置产能、调整产品结构、提高加热炉热效率、应用低温余热回收技术等措施,可以有效提高装置生产效率、降低装置生产成本,从而实现芳烃联合装置降本增效的目的。

Abstract: As a typical high-energy consumption unit, the aromatic hydrocarbon complex has a large energy-saving space. To further improve the economic benefits of the unit and reduce its operating costs, an analysis was conducted on the energy consumption composition of a company's aromatics complex to determine the main sources of energy consumption for the aromatics unit. Through energy analysis of the unit, the main direction of energy-saving efforts is to increase the production of aromatic hydrocarbon products and control the consumption of fuel, steam, and electricity. Based on the actual production and operation situation, the energy-saving and consumption reducing methods for aromatic hydrocarbon complex units were explored. By increasing the production capacity of the unit, adjusting the product structure, improving the thermal efficiency of the heating furnace, and applying low-temperature waste heat recovery technology, the production efficiency of the unit can be effectively improved, the production cost of the unit can be reduced, and the goal of reducing costs and increasing efficiency of aromatic hydrocarbon complex units can be achieved.

Key words: aromatic hydrocarbon complex, energy consumption, low temperature heat, reduce cost and increase efficiency
