糠醛精制装置的能耗分析及节能措施

 通过对中国石油克拉玛依石化公司Ⅱ套糠醛精制装置的能耗构成进行分析，发现装置能耗主要由燃料气消耗、自产蒸汽用量、电耗和循环水用量决定。提出降低装置能耗的具体措施，并在检修期间进行整改。通过加热炉节能改造、优化换热流程、停用萃取塔底循环回流冷却器和机泵加变频调速器等措施，使装置的燃料气用量、自产蒸汽用量、循环水用量和电耗降低，装置的综合能耗降至639.95 MJ/t，比改造前综合能耗降低27.64％。

ENERGY CONSUMPTION ANALYSIS AND ENERGY SAVING MEASURES OF FURFURAL REFINING UNIT

The energy consumption of furfural refining unit in Karamay Petrochemical Company was analyzed. It was found that the energy consumption of the unit was mainly depended on the consumptions of fuel gas, self produced steam, electricity and circulating water. Some countermeasures to reduce the energy consumption were put forward and realized during revamping, such as energy saving reform of heating furnace, optimizing heat exchange flow, stop using the cooler for return stream at the bottom of extraction tower, adding frequency convertor on pumps and so on. Since then, the consumptions of fuel gas, self produced steam, electricity and circulating water reduced significantly, the total energy consumption of the unit dropped to 639.95 MJ/t, which is a reduction of 27.64% compared with the base case.
