Abstract: 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.
