Recently, Maoming Petrochemical Company's 1 million-ton/year ethylene-refined aromatic extraction tower was put into operation, and the optimized production process achieved energy savings of more than 3 million yuan per year.
The company's aromatics extraction tower was originally used for rectification separation of xylene products, and was used as a toluene separation product after the tower structure was basically unchanged. The originally designed tower pressure, temperature, feed amount, heating amount, reflux ratio, etc. None of them apply, putting pressure on the stable operation and high quality operation of the device. To this end, the company formed a research group and carefully discussed countermeasures in light of changes in the operation of the equipment. In view of the large amount of steam heating at the bottom of the tower and the high energy consumption during the operation of the toluene tower, a reduction in the reflux at the top of the tower was adopted, which resulted in a corresponding reduction in the amount of high-pressure steam heating at the bottom of the tower. The top of the aromatics extraction tower was returned from the original 16 tons/hour. Down to 10 tons / hour, the bottom of the heating capacity from 4.5 tons / hour to 3 tons / hour, and successfully saved the entire Tata temperature did not change. After the transformation, stable operation was achieved, and 36 tons of high-pressure steam was saved every day, which reduced the power consumption of the tower top return pump and the cooling water consumption of the tower cooler. The energy-saving value reached over 9,700 yuan.
